INSULATED ELECTRICAL CONDUCTOR FOR HIGH-VOLTAGE WINDINGS

摘要

An electrical conductor for high-voltage (10 kV to 800 kV) windings comprises central conductive means and an outer semiconductive layer (18). At least one electrically conductive contacting device (20) penetrates into the outer layer (18), by means of a plurality of barbs, for grounding purposes. A single contacting device may contact a plurality of turns of the wound conductor. A method of establishing electrical contact with a semiconductive polymeric material comprises causing the contacting device to penetrate into the material.
