ELECTRICAL WIRE AND CABLE

摘要

27065-168 An electrical wire comprises an electrical conductor (2), an insulating mineral layer (3) electrolytically formed on the conductor from chemically delaminated weathered mica, and a silicone polymer layer (3') and mineral layer. Preferably the layer of polymeric insulation (4) is extruded on the silicone layer. The electrical wire exhibits very good electrical properties for long periods at elevated temperatures, e.g. during a fire.
