A fixing device for an overhead insulated cable used for power supply and distribution

Abstract

The invention relates to the technical field of power supply and distribution, particularly a fixing device for an overhead insulated cable used for power supply and distribution. The device comprisesa fixed chuck and an adjustable clamping seat, wherein the fixed chuck is positioned above the adjustable clamping seat; four positioning holes are formed in each of two opposite side edges of the fixed chuck; the lower side of the fixed chuck is fixedly connected with a hanging rod; a through hole is formed in the middle of the upper side of the adjustable clamping seat; vertical sliding groovesare formed in the other two side edges of the adjustable clamping seat; the bottom end of the hanging rod penetrates through the through hole; fastening nuts are arranged on the outer side of the hanging rod and located on the upper side and the lower side of the adjustable clamping seat in a sleeving mode. The fixing device has the characteristics of a compact and reasonable structure and convenience in wiring, a sliding mode is converted into a rolling mode during wiring and wire drawing, the friction force of the surface of a cable is effectively reduced, the damage to the surface of the cable is small, a labor-saving effect is achieved, and the cable can be positioned and clamped by adjusting the distance between wire clamping rollers.

Description

technical field [0001] The invention relates to the technical field of electric power supply and distribution, in particular to an overhead insulated cable fixing device for electric power supply and distribution. Background technique [0002] Power cables are cables used to transmit and distribute electric energy. Power cables are often used in urban underground power grids, power station lead lines, internal power supply in industrial and mining enterprises, and underwater transmission lines across rivers and seas. In power lines, the proportion of cables is gradually increasing. Power cables are cable products used to transmit and distribute high-power electric energy in the main line of the power system, including 1-500KV and above various voltage levels and various insulated power cables. [0003] Power cables are widely used in power supply and distribution systems. During the installation process of power cables, they need to be fixed by fixing parts. Most of the exis...

Problems solved by technology

[0003] Power cables are widely used in power supply and distribution systems. During the installation process of power cables, they need to be fixed by fixing parts. The existing power cable fixing devices mostly adopt the method of threading and fixing cables. Although the cables can be effectively fixed, the pulling of the cables At this time, the friction between the wire ring and the cable is relatively large, which not only has a large resistance, but also easily damages the cable skin, which is not conducive to cable arrangement.
