Title:
BREAKDOWN-RESISTANT HIGH-VOLTAGE CABLE
Document Type and Number:
WIPO Patent Application WO/2022/174406
Kind Code:
A1
Abstract:
The present application provides a breakdown-resistant high-voltage cable, comprising a wire core and an insulating layer. An inner semi-conductive shielding layer is arranged between the wire core and the insulating layer; a nanopore structure layer is arranged at an interface between the inner semi-conductive shielding layer and the insulating layer; the nanopore extending direction of the nanopore structure layer is perpendicular to the extending direction of the cable. In the breakdown-resistant high-voltage cable, the interface between the inner semi-conductive shielding layer and the insulating layer is the nanopore structure layer having a nano-scale pore diameter, thereby effectively preventing interface discharge caused by a defect of the interface between the inner semi-conductive shielding layer and the insulating layer, and greatly improving the breakdown-resistant field strength of the cable.
