GB/T 9326.3-2008
ActiveOil-filled, paper or polypropylene paper laminate insulated, metal-sheathed cables and accessories for alternating voltages up to and including 500kV - Part 3: Sealing end
交流500kV及以下纸或聚丙烯复合纸绝缘金属套充油电缆及附件 第3部分: 终端
Application Summary AI generated
This standard specifies the technical requirements, test methods, and acceptance criteria for sealing ends used in oil-filled cables with paper or polypropylene paper laminate insulation and metal sheaths, designed for alternating voltages up to 500kV. It is applied in the manufacturing, installation, and quality verification of cable termination accessories for high-voltage power transmission systems, particularly in substations and long-distance underground or submarine cable lines. The standard ensures reliable electrical insulation and sealing performance at cable endpoints to prevent oil leakage and dielectric failure under operational and fault conditions.
