Waveform/wavecon cable sizing

Will Elec

Just had a quote in from Western Power for a new 100a 3 phase supply. There is approximately 100m between the pole mounted transformer and the cut out and the DNO has specified 185mm wavecon cable.. this seems like an overkill to me, the pole transformer is 50Kva and it seems like 95mm would be more appropriate!  Not sure what voltage drop on waveform cable is like but compared with regular SWA 95mm still seems plenty big enough.. Thoughts on this would be appreciated! Thanks

    Although a 50kva transformer is still being used for a 72kva 100a supply so I guess the DNOs don't mind a bit of overload!


    What kVA did you apply for?


    Did you declare any disturbing loads?


    72 kVA is in CT metering land
