Zero Sequence Impedance for 3 phase Cable

[strongone]

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.

Go to the Kerite or the Okonite cable websites.

This is difficult to calculate accurately. See these previous threads.

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

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).
