Method of manufacturing high-voltage cable and high-voltage cable manufactured thereby

Abstract

The present invention relates to a method of manufacturing a high-voltage cable. The method of manufacturing a high-voltage cable includes operation (a) of introducing a cable covered with an extruded insulating layer to which a cross-linking agent is added into a cure tube, operation (b) of increasing a temperature in a front zone of the cure tube into which the cable is introduced to perform a cross-linking process in the insulating layer and controlling a line speed of the cable through the cure tube, and operation (c) of degassing cross-linking byproducts generated during the cross-linking process at a back zone of the cure tube.
