CONTINUOUS PROCESS FOR MANUFACTURING A HIGH VOLTAGE POWER CABLE

摘要

It is disclosed a process for manufacturing an energy cable comprising at least one conductor and at least one polymeric coating layer. The process comprises: compounding a polypropylene matrix and a dielectric fluid to obtain a polymeric mixture; raising flow pressure of the polymeric mixture; filtering the polymeric mixture; causing the polymeric mixture to flow through an extrusion head to produce the coating layer on the conductor; and cooling the cable.
