    • The high voltage insulator assembly comprises an insulator connected to a mounting which is adapted to pivot on a mast or pylon. The insulator comprises an elongate glass fibre reinforced core which is encased over part of its length by a skirted insulator covering having attached thereto a lug for supporting a high voltage line and over the remainder of its length by a sleeve which is connected to the mounting, the sleeve being joined to the insulator covering to protect the core from the weather. The mounting provides a pivotal connection to a mast so that the assembly can pivot about the mast when the high voltage line is subject to loads imposed by abnormal wind conditions. The connection between the mounting and the insulator is such that the angle between the pivot axis of the mounting and the longitudinal axis of the core is greater than 30* and that the axes are coplanar.
    • 高压绝缘子组件包括连接到适于在桅杆或塔架上枢转的安装件的绝缘体。 绝缘体包括细长的玻璃纤维增​​强芯,其被其长度的一部分封装在一个裙边绝缘体覆盖物上,该外围绝缘体覆盖物通过连接到安装件的套筒附接到其上用于支撑高压线并且在其余长度上的套管, 套筒连接到绝缘体覆盖物以保护芯部免受天气影响。 安装件提供与桅杆的枢转连接,使得当高压线路受到由异常风力条件施加的负载时,组件可绕桅杆枢转。 安装件和绝缘体之间的连接使得安装件的枢转轴线和芯部的纵向轴线之间的角度大于30°,并且轴线是共面的。
