Reinforced overhead insulated cable

Abstract

The invention discloses a reinforced overhead insulated cable, which belongs to the field of power transmission and comprises a protective layer, wherein two ends of the protective layer are providedwith clamping mechanisms which are matched with each other, a rubber layer is fixedly installed and connected in the protective layer, a reinforcing layer is arranged in the rubber layer, three groupsof conductive wire tubes are installed in the reinforcing layer at equal intervals, and the reinforcing layer is filled with an insulating filler; the clamping mechanism comprises a clamping sleeve and a threaded joint; the clamping sleeve is fixedly connected to the left side of the protective layer; the threaded joint is fixedly connected to the right side of the protective layer; a threaded groove is formed in the clamping sleeve in a clamping manner, and the threaded groove is in mutual threaded connection with the threaded joint; and the left side of the clamping sleeve is fixedly connected with a fixing ring. The cable has the advantages that the strength is high, the electric power transportation is stable, meanwhile, the flame-retardant capability is good, the service life is long, the installation and the replacement are convenient, and the stability and the convenience of the electric power transportation can be effectively improved.

Description

technical field [0001] The present invention relates to the field of electric power transportation, and more particularly, to a reinforced overhead insulated cable. Background technique [0002] A cable is a power or signal transmission device, usually composed of several or groups of wires, made of one or more mutually insulated conductors and an outer insulating protective layer, to transmit power or information from one place to another. The wire at the place is usually a rope-like cable formed by twisting several or several groups of wires. Each group of wires is insulated from each other and often twisted around a center. . The cable has the characteristics of inner energization and outer insulation. The cables include power cables, control cables, compensation cables, shielded cables, high temperature cables, computer cables, signal cables, coaxial cables, fire-resistant cables, marine cables, mining cables, and aluminum alloy cables. and many more. They are all com...

AI Technical Summary

Problems solved by technology

Overhead cables are widely used in power transmission at home and abroad. Traditional high-voltage power transmission methods mostly use high-voltage overhead lines or high-voltage cable lines as transmission channels, while conventional overhead cables are often integrated, and often overhead cables need to pass through complex areas such as jungles. , so the overhead cables are relatively easy to be damaged. However, due to the complex environment during maintenance and installation, maintenance and installation are inconvenient. Therefore, an overhead insulated cable that is easy to replace and install and has better strength is required.
