Hello everyone. I am new to the forum.
I would like to ask for help regarding HV cables.
I am sizing a cable for the secondary side of a transformer, 12MVA 4.16/138kV. I searched cable manufacturers catalogue for HV cable sizes (145kV) and found that the minimum size I can find is around 400-500mm2.
Is there a minimum size of cable that should be used for HV installation?
The current in the secondary side of the transformer is only 50.2A? Should I use 400m2 even with only 50.2A? (not taking voltage drop into consideration)
Thank you very much.
