Three Phase Belted PILC Cable +ive ûive and 0 sequence impedance calcu

[APHK]

Hi Everyone

I need to calculate the positive negative and zero sequence impedance for various lengths of 1250 MCM Pilc Cable. Just wondered if anyone has a formula or could give any help.

Cheers

The Westinghouse T&D Reference Book has tables of impedance for PILC. Pos/neg and zero impedances for 3-conductor cable are included. Only conductor and sheath resistance and reactance are included for single conductor cable, but there are equations for sequence cable impedances.
