Zero Sequence Impedance for 3 phase Cable

Zero Sequence Impedance for 3 phase Cable

Zero Sequence Impedance for 3 phase Cable

(OP)
I'm trying to calculate the zero sequence impedance of the following types of cables: NYY-J, NYFGbF and XLPE-SWA. The only information I presently have on the cablye are its length, resistance, reactance and conductor size. Any help is greatly appreciated. Thanks.

RE: Zero Sequence Impedance for 3 phase Cable

Go to the Kerite or the Okonite cable websites.

RE: Zero Sequence Impedance for 3 phase Cable

Suggestion: Contact NYY-J, NYFGbF and XLPE-SWA cable tech support(s) for the sought parameters.

RE: Zero Sequence Impedance for 3 phase Cable

I have obtained some useful data from Pirelli UK for MV power cables, they are only in hard copy at the minute but I can scan & PDF them on my return to the office (19th April) if that helps).
