Tubular electrical insulator for a high voltage power transmission line

摘要

Flexible and bendable tubular electrical insulator (1) for use in a high voltage power transmission. The electrical insulator (1) has an electrically conductive carrier tube (4) that is covered by a first electrically conductive layer (5), an electrically insulating layer (6) and a second electrically conductive layer (7). The first conductive layer (5) and the insulating layer (6) are co-extruded onto the carrier tube (4) by way of co-extrusion such that the insulating layer (6) is arranged in between the first conductive layer (5) and the second conductive layer (7) in a radial direction, and such that the first conductive layer (5) is electrically connected to the carrier tube (4), wherein the first conductive layer adheres to the electrically insulating layer and wherein the electrically insulating layer adheres to the second conductive layer.
