CONTINUOUS LIQUID CURING SYSTEM FOR THE MANUFACTURE OF INSULATED CONDUCTORS

摘要

Electrical conductors are insulated in the following manner: An extrudable and curable insulating material is extruded onto a continuously advancing conductor, thereby coating the latter with a coat of the insulating material; this is done by using a conventional extruder. Then, the coated conductor is passed in an elongated curing-cooling chamber wherein the insulating material is first cured and then cooled in an appropriate liquid medium under sufficient pressure to produce void free insulation on the conductor. Then, the insulated conductor, after withdrawal from the curing-cooling chamber, can be washed, burned off to remove all traces of the curing liquid, painted, dried and printed, all on the same continuous line. The system is simple, efficient and inexpensive. It is also easily adaptable to continuous plant operations in the wire and cable industry.
