Abstract

A method for making cable of at least two thermoplastic insulated electrical conductors by thermal bonding. Two electrical conductors are moved into an extruder and are coated independently with heated thermoplastic insulation which maintains concentricity of each conductor with respect to the surrounding insulation. The insulated conductors are held in a spaced relationship until the insulation sets and then the heated insulated conductors are touched together causing the heated insulation to fuse together thereby joining them.
