MV Cables

Medium Voltage Cables support a voltage range of between 6 kV and 33 kV, making them ideal for use in infrastructure, including the distribution and transmission of power.

MV Cables

With triple-layer Cross Linked Polyethylene (XLPE) insulation, Medium Voltage Cables are highly resistant to both very high and very low temperatures, as well as moisture and chemicals, ensuring a long lifespan and fewer breakdowns. The use of XLPE also affords the benefits of the material’s excellent electrical and mechanical properties, and its low dielectric factor.

At Riyadh Cables, all XLPE insulation of our Medium Voltage Cables are done pursuant to standards outlined by IEC 60502-2 and IEC 60811. The conductors used are Stranded Class 2 of plain annealed copper or aluminum, in accordance with IEC 60228.

Standard outer sheathing on our Medium Voltage Cables is extruded PVC type ST2; special PVC sheathing can be accommodated on special request; in addition, other sheathing materials such as low smoke halogen free (LSHF), LLDPE, MDPE and HDPE are available on request.

MV Cables types

  • XLPE MATERIAL

    The trend of cross-linked polyethylene insulated cables into power cables field is quite prevalent in the world as the substitutes of paper insulated cables, which had played the leading role in electric power transmission stage. Thus, nowadays after making its impact on its use in the medium voltage cables category, the stage seems to be turning in favour of XLPE cables in the high voltage and extra high voltage range. Especially in the higher voltage area, the monopoly of paper insulated cables, such as oil filled cable or gas filled or compressed type of cables, is gradually collapsing into the co-existence with XLPE cables, which have great advantages and economical reasons such as higher permissible temperature level, ease of jointing and maintenance techniques and omission of equipment inherent to the pressurized cable

    Electrical performance of XLPE is excellent. Di-electric breakdown strength and volume resistivity are high and both Di-electric loss (tan d) and dielectric constant (e) are low. Thermal resistivity is low. XLPE insulated cables can operate continuously at a temperature of 90°C, because they have excellent heat aging characteristics. This leads to large power transmission capacity. XLPE cables are lighter in weight, they are easy to handle, easy to install and jointing and termination is easy. They are of dry type because no oil impregnation is involved.

    The insulation material for types of XLPE cables is low-density (LD) polyethylene. PE has for a long time had a wide use as cable insulating and sheath materials owing to its excellent electrical and mechanical properties, its lightness, low temperature flexibility and good resistance to moisture, chemicals, ozone etc. as well as its comparatively low price.

    Low Density polyethylene, however, has properties which limit its use as cable insulation. Being a thermoplastic, its softening temperature is 105 - II5°C. Another disadvantage is its tendency to stress cracking when in contact with certain surface-active agents.

    By means of a process reminiscent of the vulcanization of rubber, PE molecules can be cross-linked, thus greatly improving the thermal and mechanical properties of the material, while its electrical properties are retained largely unchanged. This product, cross-linked polyethylene (XLPE), is therefore no longer a thermoplastic. It assumes elastic, rubber-like consistency, a property that it retains during a further rise of temperature. The tendency to stress cracking entirely disappears and the material also acquires very good resistance to aging in hot air.

    CROSS-LINKED POLYETHYLENE

    PE is made up of long molecular chains. By cross-linked these chains a network of strong bonds is created and PE is converted into cross-linked polyethylene, XLPE. 

     

    THERMAL PROPERTIES

    Owing to the cross-linking, XLPE is a very heat-resistant material. It cannot melt like polyethylene but decomposes and carbonizes if exposed for long periods to temperatures above 300°C.

    The permissible conductor temperature during short-circuit for 1 second has therefore been put at 250°C and under continuous load, conductors with XLPE insulation may have a temperature of 90°C. These temperatures are specified by International standards. In emergency conditions and for limited period, XLPE can withstand l30°C.

    XLPE, like PE, retains its low temperature flexibility down to - 40°C, which implies great advantages during laying of cables.

    ELECTRICAL PROPERTIES

    The good electrical properties of PE remain largely unchanged during cross-linking process. XLPE therefore, like PE, has a very small and insignificant temperature dependant loss factor (tan d) and dielectric constant (e). As a result the dielectric loss of XLPE cables are small in comparison with those of PVC and paper insulated cables. XLPE cables are specially adapted for long cable routes and high voltages, in both cases where dielectric losses are of great significance.

    MECHANICAL PROPERTIES

    Polyethylene has good mechanical properties. It is interesting that at normal temperature PE can resist local stresses better than PVC. In this respect XLPE has the same advantageous properties as PE and certain grades, such as filled XLPE insulation also resists abrasion much better than polyethylene.

    CHEMICAL PROPERTIES

    Owing to the cross-linking of molecules XLPE has better resistance than PE to most chemicals such as ordinary acids, bases and oil.

    ENVIRONMENTAL POLLUTION AND CABLES

    From the environmental aspect, both PVC and oil-impregnated paper-insulated cables have distinct disadvantages. When PVC cables bum they give off corrosive gases, and a leaking oil- filled cable may cause severe damage to environment.

    XLPE admittedly bums, but the products of combustion carbon dioxide and water do not cause damage. Filled XLPE used for low voltage cables can also be made resistant to flame propagation and the compound does not produce halogen.

    Cross-linking Process

    Cross-linking is done by agent di-cumyl peroxide (DCP). Cross-linking takes place in the CCV Tube under heated and pressurized Nitrogen where DCP decomposes into two radicals, which react with Polyethylene thereby causing cross-linking.

    Peroxide is already mixed at the material supplier's plant with proper balance of anti-oxidant and peroxide to ensure the required thermal stability and optimum curing level. Therefore, no mixing whatever is done during production. This will prevent problems which might occur due to the unbalanced mixing of material during production stage. Un-packing and handling of the material is also done in similar super clean environment at Riyadh Cables Group of Companies.

    The mixing ratio is about 1 to 1.5 PHR with very small amount of anti-oxidant. The cross-link residual is gas, which defuses out of the insulation gradually. Other residuals are Acetophone and Cumyl-alcohol which are in very low ratio, Research in this regard has proven that this material has very good effect on insulation such as:

    • It improves the breaking strength when inclusion occurs in XLPE material.
    • It slows water tree growth in the XLPE material under service.

    RCGC employs in-line dry curing for all its CCV lines alongwith State-Of-The-Art Triple Cross-Head extrusion where the Conductor Screen, Insulation and Insulation Screen are extruded simultaneously by means of a Triple Cross Head which has the following advantages:

    • Reduces micro voids and moisture content in insulation and ensures enhanced and stable breakdown strength and uniform insulation structure.
    • Ensures extremely accurate layer thickness.
    • Ensures high purity in the frontier limit between the semi-conductive layers and the insulation.
    • Provides optimal fusion of the individual layers without contamination.
    • Ensures a firm bond and smooth interface between each layer thus improving electrical properties.
    • Prevents unforeseen damage to the conductor or insulation screen during manufacturing process.

    The above are optimized by the use of an X-Ray unit located immediately after the cross-head which provides a transparent view of all three layers. This arrangement also facilitates recording the trend every 2 seconds. The unit continuously scans 360° geometry of the cable and displays the maximum, minimum and eccentricity of all three layers separately. Any deviation between the specified values and the measured values are recorded and adjusted automatically.

    Also incorporated in the CCV line is the "Twin-Rot" system, one of the latest in manufacturing technology which ensures superior control of eccentricity and eliminates the possibility of "Pear Drop" since the cable rotates during manufacture.

    I. DRUM HANDLING 
    • Unloading the drum should be by forklift or crane, rolling should be avoided.
    • If the above equipment are not available, rolling as per direction on special constructed ramps is allowed with a slope of 1/4 (q = 14 degrees)
    • When the reels are lifted by an axle supported from above, a separator bar must be employed to prevent damage to the conductor or reel, or both, by inward pressure on the reel flange.
    • Drum should not be dropped on the ground under any circumstances even on soft material.
    • Drums should be kept in the up-right position.
    • Be sure that the end seal cap is still in place.
    • Drums should be covered all the time.
    • Avoid moving the drum from one place to another as this may help in loosening the conductor windings.
    • Remember always that conductor is a high commodity value and it is very sensitive to damage and must be handled with necessary care.
    II. PREPARATION AND CONDUCTOR PULLING
    • Drum flange bolts should be inspected and tightened as they may get loosened during drum transportation and frequent handling.
    • Conductors should be inspected before erection to ensure that it is minimum pulling tension which can be achieved.
    • Location of drum prior to pulling can be decided based on minimum pulling tension which can be achieved.
    • Drums should be normally mounted so that the cable is pulled from the top of the drum
    • Minimum permissible bending radius shall be as recommended by the manufacturer.
    • Conductor pulling tension should not exceed 70% of conductor sagging tension, or 15% of the conductor breaking through.
    • Bearing pressure on the conductor at the bend should not be exceeded as to avoid strand notching.
    • Care should be taken at all times to ensure that conductors do not become kinked, twisted, abraded or damaged and that foreign matter does not become deposited on them.
    • It is preferable to use sheaves that line up with a conductive type neoprene or urethane to protect the conductor.
    • Sheaves should be clean and smoth to avoid any damage to the conductor.
    • Sheaves diameter should be minimum 20 times and 40 times conductor diameter for OHL and OPGW respectively.
    • Conductor tensioner (capstan) should be used for conductor pulling and not direct from the conductor drum.
    • Conductor tensioner should have a minimum of five turns of the conductor.
    • Wheels of the "bull-wheel" tensioner and "bull-wheel" puller should have multiple groove lines with neoprene or other approved non-mettalic resilient material so that conductor will cushion into the lining to prevent flattening otherwise conductor may be damaged.
    • V-Groove type bull-wheels should be avoided.
    • Groove diameter should be at least 1.25 conductor diameter, while "bull-wheel" should have a minimum bottom groove diameter of 40 times and 70 times the conductor diameter for OHL and OPGW respectively. 
    • Tandem bull-wheels should be so aligned that the offset will be approximately one-half the groove spacing. For normal conductors having a right-hand direction of lay for the outer wires, bull wheels should be arranged so that, when facing in the direction of pull, the conductor will enter the bull wheel on the left and pull of from the right side. For any conductors having a left-hand direction of lay of the outer wires, the conductor should enter on the right and pull off from te left. This arrangement is necessary to avoid any tendency to loosen the outer layer of strands as the conductor passes over the bull wheels.
    • Possibility of breaking the drum anytime should be prepared as in sudden stoppage of conductor pulling. Continuation of drum rotation can cause sharp bending of the conductor.
    • The pulling and breaking systems should operate smoothly and should not cause any sudden jerking or bouncing of the conductor. Each system should be readily controllable and capable of maintaining a constant tension.
    • Pullers should be equipment with load-indicating and load-limiting devices. The load-limiting device should automatically stop the puller from acting further if a preset maximum load has be exceeded. Tensioners should be equipped with tension indicating devices.
    • Tensioner bull wheels must be retarded so that conductor tension may be maintained a various pulling speeds.
    • During pulling the inner end of the conductor might be projected more and more, then it is necessary to interrupt the pulling from time to time in such cases for re-securing the said end.
    • The conductor should preferably be drawn in a continuous manner. During stops, it may settle between sheaves and sheaves suspension holder and may cause high strain on conductors during re-starting.
    • To avoid birdcaging allow enough dicstance between the reel and tensioner to permit the strand looseness to distribute along the intervening length of conductor and simultaneously maintaining enough back tension on the reel of stretch the core and inner strands to sufficiently tighten the outer strands. It is recommended that the back tension or breaking tension of the conductor reel not exceed 4.5 kN, since drawing down of the conductor into the lower layers on the reel may cause surface damage. For smaller diameter and wooden reels, the back tension should be considerably less. Excessive back tension on the reel can,

      a) Deform the reel flanges leading to tangles in the conductor,
      b) Scratch or damage to the adjacent conductor layers and/or
      c) Crush the reel drum.
    • Brake at pay-off should be lowered to the minimum to avoid conductor insertion in case windings are loose due to long time storage or any other reason.
    • In case difficulty use motorized pay-off so tension at the conductor on the drum shall be approximately nil.
    • Dependable communication shall be maintained between the line - men operating the pulling equipment and the tensioning equipment and obseving at intermediated locations at all times during the conductor stringing operation. Conductor over pulling or conductor loosening and sudden tension shall be avoided as this may damage the conductor.
    • Avoid conductor twisting by using swivel on the pulling line followed by anti-rotation device as this may cause birdcaging.
    • Conductor end should be always tightened so stranding loosening can be avoided.
    • At the bend, conductor shall be guided by sheaves. Direct touch with tower side shall be completely avoided.
    • The conductor should be grounded whild it is being installed; the grounding conductor must be large enough to adequately conduct fault current to ground without fusing.
    • Immediately after cutting, the conductor end must be suitably secured.
    • It is recommended to inspect the conductor after pulling to ensure that it has not been damaged.

  • CABLE PULLING, LAYING AND HANDLING INSTRUCTIONS

    DRUM HANDLING :

    • Unloading the drum should be by forklift or crane, rolling should be avoided.
    • If the above equipment are not available, rolling as per direction on special constructed ramps is allowed with a slope of 1/4 (q = 14 degrees)
    • Drum should not be dropped on the ground under any circumstances even on soft material.
    • Drums should be kept in the up-right position.
    • Be sure that the end seal cap is still in place.
    • Drums should be covered all the time.

    PREPARATION, CABLE PULLING AND LAYING:

    • It is recommended to dig a trial hole in the cable route which shall indicate the position of other services and a smooth bend can be provided to reduce the pulling load on the cable.
    • Drum flange bolts should be inspected and tightened as they may get loosened during drum transportation and frequent handling.
    • Cable should be inspected before laying to ensure that it is damage free.
    • Location of drum prior to pulling can be decided based on minimum pulling tension which can be achieved.
    • Drums should be normally mounted so that the cable is pulled from the top of the drum and for very heavy cables it may be necessary to use a ramp to support the cable during passage into the trench. When cables have significant stiffness, e.g. those with HDPE outer sheaths, it may be preferable to pull from the bottom to reduce the tendency for the cable to come off with a wavy or spiral profile.
    • The cable should preferably be drawn to its final position is a continuous manner. During stops, it will settle between rollers and may cause high strain on machines during re-starting.
    • When pulling cables beside existing cables, special care should be taken to avoid damage to the existing cables.
    • Precautions should be taken such as clearing all excavated material from the trench edges, using vertical timbers etc., so that no stones or sharp objects shall fall onto the cable.
    • Minimum permissible bending radius shall be as per Table -I and Table -2.
    • Maximum pulling tension should be as per Table -3.
    • Side wall pressure at the bend should not be exceeded.
    • Remember always that cables is a high commodity value and it is very sensitive to damage and must be handled with necessary care.
    • Possibility of braking the drum anytime should be prepared as in sudden stoppage of cable pulling. Continuation of drum rotation can cause sharp bending ofthe cable.
    • During pulling the inner end of the cable might be projected more and more, then it is necessary to interrupt the cable pulling from time to time in such cases forre-securing the said end.
    • Depth oflaying shall be minimum 0.6 meters under footpath and 0.8 meters under roads for Low Voltage and Medium Voltage cables while it shall be around 1.5 meters for High Voltage cables.
    • Layer of sand 10 cm approx. under and over the cable shall be finished. Then a layer of brick or tile shall be placed for warning, mechanical protection, load distribution.
    • When pulling the cable inside conduit/pipe the inner diameter of the pipe shall be min. 1.5 times the cable diameter.
    • It is preferable to use pipe with funnel shape, cable should not rest at the sharp edges of the pipe, special care should be taken such that stones and other objects are not dragged with the cable inside the pipe.
    • Pipe should be cleaned before pulling operation.
    • Special lubricant can be used to minimise the cable friction with the pipe wall.
    • When cables of different voltages are laid together it is preferable that the higher voltage to be laid down, then the lower voltage and then lower voltage. High voltage cables should be separated by a covering slab from the other cables.
    • For direct buried installations, rollers at a distance of around 1-2 meters are to be used based on cable weight, in any case cable should not touch the ground, It is recommended to use motorised rollers at the distance of 20 M to 30 M with proper monitoring. These are beside the normal cable rollers specially near bending points so that the cable pulling force shall be distributed evenly over the complete length of the cable. This kind of pulling is recommended when there are many bends in the cable route.
    • For cable pulling, cable stocking can be used for Steel Wire armoured cables while for non-armoured cables and Steel Tape armoured cables pulling head is preferred. Special care shall be taken to seal the cable head avoiding water penetration during pulling.
    • It is not advisable to use cable pulling stocking when the ambient temperature is around 45°C or more and under direct sunlight as the outer jacket might soften and get damaged.
    • It is recommended to use pulling head when the cable is pulled inside pipes or conduits as slipping of stocking might occur inside the pipe or conduit.
    • While pulling, continuos monitoring of the tensile force should be maintained.
    • At the bend, cable shall be guided by rollers. Direct touch with trench wall shall be completely avoided.
    • Immediately after cutting, the cable ends must be suitably sealed so that there is no ingress of moisture.
    • It is recommended to inspect the cable after laying to ensure that the cable has not been damaged.
    • Cable after laying should not be straightened but left with slight meandering to allow longitudinal expansion and contraction during thermal cycling.
    • When the ground water table is high it is advisable to use special cable construction with longitudinal and radial watertight characteristics.

    CONSIDERATION FOR CABLE CURRENT RATING :

    When laying cables special attention should be given to:

    • Cable spacing.
    • Any other cable passing by, in parallel or crossing as this might affect considerably the cable rating.
    • Any other heat source which might be near the cable as this shall have the same effect as point no. 2.
    • Drying effect of soil on the value of soil thermal resistivity and side effects on currentrating.
    • Avoid connecting the armour and sheath at both ends for single core cables as this shall reduce the current rating of the cables considerably but special attention should be given to induced voltage in both normal operation and short circuit.
    • The deeper the cables are laid lower is the ampacity of cables.
    • If cables are passing through pipes for more than 6 meters then the pipe derating factor should be considered.
    • Avoid pulling single core cable inside steel pipe or any other magnetic material as this shall cause high losses and cable overheating.
    • Soil thermal resistivity of the actual ground at different places ofthe trench shall be measured to ensure that the value is matching the one used for current rating computation.

    TABLE IV - Permissible pulling force in the laying of LV, MV and HV cables

    Means of pulling Type of Cable Formula Factor
    With pulling head attached to the conductors All types of calbes P = σ . A σ = 50 N/mm² Copper Conductor
    σ = 30 N/mm² Alum. Conductor
    With pulling stocking Un-armoured Cables* P = σ. A σ = 50 N/mm² Copper Conductor
    σ= 30 N/mm² Alum. Conductor
    Armoured Cables P = k . d² k = 9 N/mm²
    Lead Sheath Cables P = k . d² k = 3 N/mm²

    When pulling 3 single core cables simultaneously with a common pulling stocking. the same maximum pulling force applies, whereas the puliing force 3 laid-up single core cables is 3 times that of a single core and for 3 non-laid-up single core cables is 2 times that of a single core.

    ** Not applicable for high voltage cables
    P = Pull in N
    A = Total cross sectional area in mm² of all conductors (but not screen or concentric conductor)
    d = Outside diameter of the cable in mm
    σ = Permissible tensile stress of conductor in N/mm²
    k = Empirically derived factor in N/mm²
