Insulated electrical conductor

摘要

An electrical conductor for high-voltage (10kV-800kV) windings comprises a central electrically conductive core and an outer semiconducting layer. A contacting device 20 comprising a resilient metallic spring member contacts the outer layer for grounding purposes. Alternatively, a single contacting device in the form of an elongate helical spring 40 may contact a plurality of turns of a wound conductor 10.
