    • An electrically insulating cross-arm for a tower for high-voltage power networks. The cross-arm includes an insulating structural member for attachment to the tower body and to support a conductor cable. The insulating structural member comprises a solid rigid spine extending along a long axis having cross sectional profile, normal to the long axis, having a second moment of area of its cross sectional profile about every axis normal to the long axis and dissecting its centroid has a value of A2/2π or more, where A is the area of the cross sectional profile. The structural member provides resistance to bending and compressive buckling and allows conductors to be safely supported at reduced tower height. T and Y shaped cross sections provide water run-off and inhibition of organic growth. The structural members are also generally useful as insulator members in high voltage power networks.
    • 一种用于高压电网的电绝缘交叉臂。 横臂包括用于附接到塔体的绝缘结构构件并且支撑导体电缆。 绝缘结构构件包括固定刚性脊柱,其沿长轴延伸,具有垂直于长轴的横截面轮廓,具有围绕垂直于长轴的每个轴线的横截面轮廓的面积的第二力矩,并且解剖其重心具有 A2 / 2&pgr的值 或更多,其中A是截面轮廓的面积。 结构构件提供抗弯曲和压缩屈曲的阻力,并且允许导体在减小的塔架高度处被安全地支撑。 T形和Y形横截面提供水流失和抑制有机生长。 结构构件也通常用作高压电力网络中的绝缘体构件。
