Abstract

An electrical wire comprises a copper conductor and an electrical insulating refractory coating. At least part of the coating and preferably all the coating has been formed by a sol-gel method. In addition, the conductor includes a keying layer formed from a metal other than copper in order to increase the adhesion of the refractory coating to the conductor. The keying layer may be formed for example by electroplating, rolling or wire drawing methods.
