在高电压组件（10），例如 通过高电压电势的光导体，用于高电压室外安装电流互感器设备，Messinforamtionen在接地电势被发送。 为了减小电压梯度沿高电压侧（9）和一个高压绝缘体（6）螺旋形沿着光波导支撑件（7）的接地电位侧（5）之间的光纤的该被引导。 光纤支撑件（7）可以是自支撑的塑料线圈（7）或玻璃纤维的绝缘体管的外层增强高电压绝缘体（6）或它的外部施加的硅树脂层或硅氧烷屏蔽带的塑料。 这里，光导体载体的表面泄漏是大于1.5倍，优选大于5倍的高度（h）的高电压绝缘体（6）的。 光导可以与大节距螺旋缠绕或设置在螺旋线的U形槽，或在管状螺旋的空腔中。

In a high-voltage module (10), such as the current transformer arrangement for a high-voltage outdoor installation, Messinforamtionen via optical fibers of high-voltage potential are transmitted to ground. In order to reduce the voltage gradient along the light guide between this high-voltage side (9) and the ground potential side (5) of a high-voltage insulator (6) being spirally conducted along an optical waveguide support (7). The optical fiber support (7) can be a self-supporting plastic helix (7) or the outer layer of the insulator tube of glass fiber reinforced plastic of the high-voltage insulator (6) or its outside applied silicone layer or the silicone sleeve band. Here, the surface leakage of the optical waveguide support is greater than 1.5 times, preferably greater than 5 times the height (h) of the high-voltage insulator (6). The light guide can be wound on the spiral with large pitch or arranged in a U-shaped groove of the helix or in the cavity of a tubular helix.
