Abstract
Abstract A heat resistant, asbestos insulated electrical wire comprising a metallic conductor, a body of asbestos fiber surrounding the conductor, an enclosing braid of refractory and thermoplastic filaments, and a covering of thermoplastic film; and the method of making same. The thermoplastic filaments of the braid are fused to the underlying body of asbestos, and the covering of thermoplastic film is fused to the surface of the underlying braid.
