Abstract

The invention relates to a self-heat-dissipation high-voltage cable. The self-heat-dissipation high-voltage cable comprises a central copper pipe, a Z-shaped conductor, a split conductor and a compressed conductor are sequentially arranged outside the central copper pipe, and at least one layer of compressed conductor is arranged. A conductor shielding layer, an insulating layer and an insulatingshielding layer are arranged outside the compressed conductor, wherein each layer is uniform in thickness. a buffer layer is arranged outside the insulating shielding layer, a metal sheath is arrangedoutside the buffer layer, an anti-corrosion layer is arranged outside the metal sheath, an outer sheath is arranged outside the anti-corrosion layer, an electrode layer is arranged outside the outersheath, and the Z-shaped conductor is composed of Z-shaped conductive single bodies. The self-heat-dissipation high-current-carrying capacity is achieved, and losses in the operation process are effectively reduced.

Description

technical field [0001] The invention relates to a cable, in particular to a high-voltage cable. Background technique [0002] The development of domestic high-voltage power systems is getting faster and faster, and the voltage level of the power cables used is getting higher and higher. During the operation of the cables, the line loss will become larger and larger, resulting in power loss. [0003] Setting a self-heating structure in the cable structure can reduce the temperature during the operation of the cable, and at the same time improve the current carrying capacity of the cable, reduce the AC resistance of the conductor, reduce the loss, and improve the safety of the cable operation and the service life of the cable. SUMMARY OF THE INVENTION [0004] Purpose of the invention: The purpose of the present invention is to overcome the deficiencies in the prior art, and to provide a self-heating high-voltage cable with high current-carrying capacity for self-heating and...
