Tests on oil-filled and gas-pressure cables and their accessories. Part 2: Internal gas-pressure cables and accessories for alternating voltages up to 275 kV
充油和气压电缆及其附件的试验 - 第2部分:交流电压高达275 kV的内部气压电缆和附件
Applies to tests on internal gas-pressure cables and accessories intended to be used in systems with a nominal voltage not exceeding 275 kV between phases, and in which, during normal operation, a gas pressure exceeding 12 kg/cm2 is applied internally (i.e. with the gas in direct contact with the insulation).
