这是CAN/CSA-C156.2复合电站支柱绝缘子的第一版。本标准规定了在标称电压大于1000 V且频率不大于100 Hz的情况下运行的户外用复合电站支柱绝缘子的电气、机械、尺寸特性、试验方法和验收标准。站用支柱绝缘子主要用作开关设备中的支架或操作元件，或用作母线或其他设备支架。电站支柱绝缘子承受拉伸、悬臂、扭转和压缩载荷。本标准涉及带金属配件的实心复合绝缘子和带棚的外壳。 芯部采用树脂浸渍玻璃纤维。带棚的壳体由弹性体组成（例如硅胶、乙丙橡胶）。金属配件是铝、钢或铁。

This is the first edition of CAN/CSA-C156.2, Composite station post insulators. This Standard specifies the electrical, mechanical, dimensional characteristics, test methods, and acceptance criteria for composite station post insulators for outdoor service, operating at nominal voltages greater than 1000 V and frequency not greater than 100 Hz. Station post insulators are mainly used as support or operating elements in switching equipment, or as bus bar or other equipment supports. Station post insulators are subjected to tensile, cantilever, torsional, and compressive loads. This Standard deals with composite insulators having a solid core with metal fittings and housing with sheds. The core has resin-impregnated glass fibres. The housing with sheds consists of elastomers (e.g., silicone, ethylene propylene). The metal fittings are aluminum, steel, or iron.
