摘　　要：介绍了±800 kV直流系统用耐污型户外棒形支柱瓷绝缘子的设计、试制情况。根据产品特点进行了优化设计:每柱绝缘子由六节元件通过螺栓连接组成;每节元件由瓷件组成,金属附件由高强度水泥胶合剂胶装而成;伞形采用大小伞交替、伞下无棱形式。对特高压系统用支柱绝缘子的结构抗震稳定性进行了计算,结果表明,可满足九度地震烈度地区。The design, trial production and tests of the ±800 kV post porcelain insulator for D.C. system was introduced. Based on service features the product design was optimized, consisting of 6 porcelain units connected with bolts and cemented with flanges by high strength cement. The porcelain sheds are of alternative profile without arris under umbrella. Calculation shows that the post insulator column can withstand 9th scale in respect of seismic resistance.
