DC DC A METHOD OF MANUFACTURING A HIGH-VOLTAGE DC CABLE JOINT AND A HIGH-VOLTAGE DC CABLE JOINT

摘要

A high voltage DC cable joint comprising a multi-wall stacked configuration having individual concentrically arranged layers. The joint includes, from the inside to the outside, an inner conductive rubber layer 1, a field grading rubber layer 2 made of a predetermined customized preparation, an insulating rubber layer 3, and an outer conductive rubber layer 4. The field grading rubber layer separates and interconnects the conductive rubber layers, and the rubber layers are crosslinked by the by-product manufacturing method. Cable joints are preferably produced by molding process steps from platinum cured rubbers. In a preferred embodiment, the cable joint is made by injection molding.
