The code numbers to be read in conjuction with 04020701 at the beginning.

Code number for different types of insulation screen : replace the 6th digit as follows:
7 for STRIPPABLE + LEAD; 8 for BONDED + LEAD; 9 for GRAPHITE + LEAD

Example: for 150 mm² Strippable + Lead cable, the code number is 0402070116.
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.
