  1. The code numbers to be read in conjuction with 03020123 at the beginning and "L" at the end.

    Example: for 150 mm² the code number is 0302012316L

    Code number for different types of insulation screen : replace the 6th digit as follows:
    2 for S + CUW; 3 for B + CUT; 4 for B + CUW; 5 for G + CUT and 6 for G + CUW

  2. For Copper Tape screen only.

  3. Laying Conditions : Underground temperature of soil 20°C, Ground Thermal resistivity 100°C cm/W, ambient temperature 30°C.

    For other laying conditions, please refer to Table nos. 1 - 5 for derating factors.
