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 with individual concentrically arranged layers. The joint comprises, from the inside to the outside, an inner conductive rubber layer (1), a field grading rubber layer (2) made of a predetermined custom formulation, an insulating rubber layer (3) and an outer conductive rubber layer (4). A field graded rubber layer separates and interconnects the conductive rubber layers, and the rubber layers are crosslinked by a byproduct-free method. The cable joint is preferably produced by molding process steps from platinum vulcanized rubbers. In a preferred embodiment, the cable joint is produced by injection molding.
