Multi-cable composite high-voltage power cable

Abstract

The invention discloses a multi-cable composite high-voltage power cable. The multi-cable composite high-voltage power cable comprises a mounting piece, three ends of the mounting piece are provided with a plurality of second connecting holes at equal intervals; the middle part of the interior of the mounting piece is provided with second heat dissipation holes; the second connecting holes and the second heat dissipation holes are arranged in a through manner; three ends of the mounting piece are provided with first heat dissipation holes penetrating through the three ends of the mounting piece; the three first heat dissipation holes are parallel to the second heat dissipation holes; and a plurality of first connecting holes are formed in the opposite side walls in the second heat dissipation holes at equal intervals in a penetrating mode. The heat dissipation capacity of the cable can be well improved, potential safety hazards caused by heat accumulation are avoided; the weight of the cable can be effectively reduced, the use of the cable is convenient; a shielding effect can be effectively achieved, signal influences are guaranteed, the signal transmission quality is improved; and the cable can be efficiently connected with a matched cable, the working time needed by cable installation is shortened, and the firmness of connection is ensured, and the practicability of the product is improved.

Description

technical field [0001] The invention relates to the technical field of power cables, in particular to a multi-cable composite high-voltage power cable. Background technique [0002] Power cables are cables used to transmit and distribute electric energy. Power cables are often used in urban underground power grids, outgoing lines of power stations, internal power supply of industrial and mining enterprises, and underwater transmission lines across rivers and seas. [0003] Existing power cables are generally used purely to transport electricity. In order to save installation costs, a composite high-voltage cable is designed, but high-voltage cables will affect weak current cables, resulting in unsmooth information transmission and affecting the quality of its transmission. At the same time, the high-voltage cable will also generate a lot of heat, which will affect the operation of the equipment and is not conducive to normal use. Therefore, we have proposed a multi-cable com...
