22kV Transformer
22 kV requires a higher insulation level (BIL) and correspondingly rated switchgear and cable, so it suits larger industrial sites and district distribution networks.
22 kV is used where larger loads or longer distribution distances make 11 kV uneconomical. At the same power, doubling the voltage halves the current and reduces cable losses substantially.
