Abstract
Apparatus is provided for continuous manufacture of insulated conductors and includes an extruder and an elongated chamber having a first curing section immediately following the extruder and a second cooling section following the first section. Both sections are substantially filled with a same liquid medium which remains liquid under both curing and cooling conditions. Means are provided for continuously advancing an electric conductor through the extruder wherein a coat of a curable insulating material is applied thereon and then into and through the chamber filled with the liquid medium. The apparatus further includes means for maintaining the liquid medium in the chamber under sufficient pressure to produce void free insulation, and means for maintaining the liquid medium in the first section of the chamber at a temperature at which the insulating material is cured, and in the second section of the chamber at a cooler temperature to cool the cured insulating material. The system is simple, efficient and inexpensive. It is also easily adaptable to continuous plant operations in the wire and cable industry.
