Abstract

This paper describes the results of dielectric studies of commercially available "Ceramawire" and "Fujithermo M" ceramic insulated wires have been conducted at selected temperatures in the range of 20 °C to 400°C. The current-voltage characteristics provide information on conduction mechanisms and changes in the magnitude of the leakage current with temperature have been obtained. The optimal curing regime for "Fujithermo M" wire necessary to form the ceramic insulating coat, has been identified. DC breakdown characteristics of twisted pairs of "Ceramawire" and "Fujithermo M" have been measured as a function of temperature. These data provide information on the temperature behaviour of the ceramic system.
