High-voltage cable

Abstract

The invention discloses a high-voltage cable comprising a plurality of twist wire conductors, the high-voltage cable further comprises a filling tube, the plurality of twist wire conductors are distributed on the periphery of the filling tube, a shielding layer covers the exterior of each twist wire conductor, an insulation layer covers the periphery of the plurality of twist wire conductors, a non-woven fabric layer covers the periphery of the insulation layer, an inner protective sleeve covers the periphery of the non-woven fabric layer, a steel tape armoring layer covers the periphery of the inner protective sleeve, and a PVC protective sleeve covers the periphery of the steel tape armoring layer. The high-voltage cable has the advantages that the shield layer covers the exterior of each twist wire conductor, anti-interference intensity is high, the steel tape armoring layer covers the periphery of the inner protective sleeve, armoring is firm, strength of extension is large, and the high voltage cable is suitable for laying of various high voltage power lines.

Description

technical field [0001] The invention relates to a cable, in particular to a high-voltage cable. Background technique [0002] The optical cable and the phase conductor of the power transmission line, the overhead ground wire and the power cable are combined into one structure, that is, the optical cable. This structure has the dual functions of ground wire and communication. Optical cables are laid along high-voltage power lines, but ordinary cables cannot cope with high or low temperature weather, and the tensile strength is low. The main reason is that the armored part of the cable is not in place. Therefore, it is necessary to provide a new technical solution to solve the above problems. Contents of the invention [0003] The object of the present invention is to provide a high voltage cable with high tensile strength. [0004] The technical scheme adopted in the present invention is: [0005] A high-voltage cable, including a plurality of twisted wire conductors, it...
