Abstract
An electrical wire for use in high temperature applications made by providing refractory fibers that are larger than one micron in diameter and made of nonmetallic mineral material that has a melting point greater than 1200.degree. F., and applying the fibers and a binder to an electrically conductive core, to form an insulating coating around the core.
Claims6
An electrical wire for use in high temperature applications, said wire comprising
- an electrically conductive core, and
- an insulating coating of a carded mixture comprising refractory fibers that are larger than one micron in diameter and made of essentially nonmetallic mineral material that has a melting point greater than about 1200.degree. F. and holding fibers that are longer than the refractory fibers and are sufficiently long to hold the refractory fibers in place at elevated temperatures and are made of a material that has a lower melting point than said refractory fibers.
