Tests on oil-filled and gas-pressure cables and their accessories. Part 4: Oil-impregnated paper-insulated high pressure oil-filled pipe-type cables and accessories for alternating voltages up to and including 400 kV
充油和气压电缆及其附件的试验 - 第4部分:400kV及以下交流电压的油浸纸绝缘高压充油管式电缆和附件
Specifies routine, special and type tests on single-core, radial field, oil-impregnated paper-insulated cables with skid wires intended for installations in a pipe filled with oil under pressure and their accessories.
Applies to tests on complete installation i.e. when these cables and accessories have been installed and the pipe filled with oil and pressurized. Also applies to cables and accessories which normally operate with a minimum pressure of 1000 kPa (10.0 bar) and a maximum pressure of not more than 2 000 kPa (20.0 bar) and to cables and accessories with a maximum
pressure exceeding 2 000 kPa (20.0 bar).
