WIRE

摘要

An electrical wire comprises an elongate electrical conductor and an insulating mineral layer electrolytically formed on the conductor from a chemically delaminated weathered mica, the mineral forming the mineral layer having a dominant x-ray reflection at approximately 10 Angstroms characteristics of the mica basal spacing. The chemically delaminated weathered mica layer is able to adhere well to the electrical conductor and exhibits good electrical insulating properties at high temperatures. The wire is capable of functioning for long periods at very high temperatures e.g. during a fire, due to the presence of the weathered mica layer.
