交流电压大于1000V小于等于245 KV的复合电站支柱绝缘子.定义、测试方法和验收标准

[中文适用范围]： 本国际标准适用于由树脂浸渍纤维制成的承载圆柱形绝缘实心芯、弹性体材料（例如硅树脂或乙烯丙烯）制成的外壳（绝缘实心芯外部）和连接到其上的端部金具组成的复合电站支柱绝缘子。绝缘芯。本标准涵盖的复合电站支柱绝缘子承受悬臂、扭转、拉伸和压缩载荷。它们适用于交流电压大于 1000 V 至 245 kV 的变电站。 [外文原描述]： This International Standard applies to composite station post insulators consisting of a load bearing cylindrical insulating solid core made of resin impregnated fibres, a housing (outside the insulating solid core) made of elastomer material (e.g. silicone or ethylene-propylene) and end fittings attached to the insulating core. Composite station post insulators covered by this standard are subjected to cantilever, torsion, tension and compression loads. They are intended for substations with a.c. voltages greater than 1 000 V up to 245 kV.
