Problems solved by technology

When the above-mentioned cables are connected during construction, the insulation layer and the outer sheath need to be stripped. The stripping requires professional tools and needs to be carried out without electricity, which brings trouble to the construction.
In addition, in the prior art, it is necessary to twist the electric wire and the electric wire for power transmission when taking electricity. When the diameter of the wire and cable conductor is large, it is usually very difficult to connect, and it is time-consuming, laborious, and the connection effect is poor; In switchgear and other occasions, it is usually necessary to lead out multiple wires from a certain wire, and then shunt them. The branch line is powered off, and the contact resistance at the joint is increased, so the heat is very serious, which affects the life of the cable

Abstract

The invention belongs to the technical field of electric power and cables, and discloses a cable which is provided with a protection body, a first conductor and a second conductor, and is characterized in that the protection body, the first conductor and the second conductor have special structures; the first conductor is composed of a first semicircular conductor and a first extension conductor, the second conductor is composed of a second extension conductor and a second semicircular conductor, and the first conductor and the second conductor are of an integrated structure; the first semicircular conductor is located in the first containing hole, the second semicircular conductor is located in the second containing hole, most of the first extension conductor is located in the third containing hole, part of the first extension conductor is located in the supporting cavity, most of the second extension conductor is located in the fourth containing hole, and part of the second extension conductor is located in the supporting cavity. The cable has the main beneficial effects of convenient power connection, no need of a wire groove, excellent heat dissipation performance, simple structure and easy replacement.

Description

technical field [0001] The invention belongs to the technical field of electric power and cables, and in particular relates to an easy-connection cable for a power switch cabinet. Background technique [0002] The cables in the prior art have single or multiple insulated wires. The so-called insulated wires are composed of conductors and insulating layers covering the conductors; multi-core cables usually use outer sheaths to cover multiple insulated wires. The multi-core cables in the prior art are also in the shape of one or more rows as disclosed in CN2742537Y. When the above-mentioned cables are connected during construction, the insulation layer and the outer sheath need to be stripped, which requires professional tools and needs to be carried out without electricity, which brings trouble to the construction. In addition, in the prior art, it is necessary to twist the electric wire and the electric wire for power transmission when taking electricity. When the diameter ...
