33kV Transformer
Because of the higher insulation level, 33 kV switchgear and installation cost more, so it is chosen where the power level or distance justifies it.
33 kV is used for large industrial intakes, heavy process plants and primary distribution networks. It carries more power over longer distances with lower losses than 11 kV or 22 kV.
Because of the higher insulation level, 33 kV switchgear and installation cost more, so it is chosen where the power level or distance justifies it.
