Abstract

A method for making mineral insulated metal sheathed (MIMS) cable is disclosed. A tube of relatively large diameter is filled with at least one electrically conducting rod and an insulator. The resultant tubular assembly is sealed, hot rolled, reduced on a pilger (tube reducer) mill and drawn into relatively thin wire cable. The method is especially suitable for thermocouple cable production. Other applications include heating cable and control cable manufacture.
