In a high-voltage-conducting assembly (10), such as, for example, the current transducer arrangement for a high-voltage outdoor installation, measurement information items are transmitted via optical waveguides from high-voltage potential to ground potential. To reduce the voltage gradient along the optical waveguide, the latter is spirally conducted along an optical waveguide carrier (7) between the high-voltage side (9) and the ground potential side (5) of a high-voltage insulator (6). The optical waveguide support (7) can be a self-supporting plastic coil (7) or the outer layer of the insulator tube of fibre-glass-reinforced plastic of the high-voltage insulator (6) or its silicon layer applied on the outside or its silicon shield tape. In this arrangement, the surface leakage path 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 optical waveguide can be wound at a steep pitch onto the coil or arranged in a U-shaped groove of the coil or in the hollow space of a hose-spaced coil. |
