充油和气压电缆及其附件的试验 - 第3部分:交流电压高达275 kV的外部气压(气体压缩)电缆和附件
Applies to tests on radial-field, impregnated-paper insulated
cables and their accessories intended to be used on systems with a
nominal voltage not exceeding 275 kV between phases, and which,
during normal operation, work under a gas pressure exceeding 12 kg
/cm2 applied outside a sheath or jacket so that the gas is not in
direct contact with the insulation.
