The Cooling Rate of Polyethylene Insulated Wire During the Extrusion Process

摘要

During the manufacture of polyethylene insulated conductors, hot polyethylene is applied to the copper conductor in the head of an extruder. Immediately after the insulated conductor leaves the extruder head, it is cooled in a trough filled with water. This paper presents a method to determine the cooling rate of the polyethylene insulation as it passes through the water trough. (Author)
