Branch connection structure of five-core cable

Abstract

The invention relates to a branch connection structure of a five-core cable. A protection shell covers connection points of a five-phase wire conductor and a branch conductor of a main cable, a spaceamong an inner wall of the protection shell, the five-phase wire conductor and the branch conductor is filled with a flexible synthesized mineral insulation material, the connection points of the five-phase wire conductor and the branch conductor are arranged in the protection shell in a staggered way along a length direction and are uniformly arranged in a circumferential direction, and the phasewire conductor and the branch conductor of the main cable are connected by die-pressing of a crimping ring, and the branch connection structure is convenient to operate and is simple in process. Theconnection points of the five-phase wire conductor and the branch conductor are arranged in a staggered way in the protection shell along the length direction and are uniformly arranged in the circumferential direction, a few space is occupied, a branch connector is small in size, production equipment and production process circuit are simple, and the branch connection structure is convenient to install, connection and operate, and is high in connection strength and good in conductive contact performance.

Description

technical field [0001] The invention relates to a five-core cable branch connection structure. Background technique [0002] Cable products in the power industry are laid along the transmission and distribution lines to transmit power to various electrical equipment; cables in the prior art are widely used as multi-core cables. Electric equipment taps the current; it is difficult to connect the conductors of the branch structure and the conductors of the main cable at the joints. In the direct overlapping connection method, each phase conductor needs to be overlapped with the corresponding conductor of the main cable at the branch position, resulting in a bulky branch cable connection structure, inconvenient layout of production equipment and production process routes, difficult installation, insufficient connection strength, and contact The performance is not good. Contents of the invention [0003] The technical problem to be solved by the present invention is to provi...

Problems solved by technology

[0002] Cable products in the power industry are laid along the transmission and distribution lines to transmit power to various electrical equipment; cables in the prior art are widely used as multi-core cables, and branch structures need to be set at the corresponding positions of the electrical equipment during cable laying so as to use Electrical equipment taps the current; and it is difficult to connect the conductors of the branch structure and the conductors of the main cable at the joints. In the connection method of direct lap connection, each phase conductor needs to be lapped with the corresponding conductor of the main cable at the branch position, resulting in a bulky connection structure of the branch cable, inconvenient layout of production equipment and production process routes, difficult installation, insufficient connection strength, and contact poor performance
