The code numbers to be read in conjuction with 02020103 at the beginning and "L" at the end.

Example: for 150 mm² the code number is 0202010316L

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
For Copper Tape screen only.
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.
