Problems solved by technology

[0002] For high-voltage transmission lines, it is necessary to limit the distance between cables according to the size of the transmission voltage to prevent arc discharge and affect the safety of power transmission
Existing cable isolators are usually hexagonal clips, which are completely fixed in size, poor in flexibility, limited in scope of application, poor in compression and corrosion resistance, and prone to aging and deformation
[0003] A multi-purpose high-voltage cable isolator disclosed in the patent application number 201510222450.X has two shortcomings in use. One is that there are many connecting adjustment parts that are not conducive to quick installation and adjustment, and the other is the semi-open "C" shape. The fixing collar is not conducive to the installation and fixing of isolated cables, and the cables are easy to fall off when they are swayed by strong winds

Abstract

The invention relates to a high-voltage cable isolating support. The isolating support comprises a mounting substrate, supporting strips and connecting bolts, wherein the supporting strips are mounted on the mounting substrate through the corresponding connecting bolts. The high-voltage cable isolating support has the advantages of simple and practical structure, high expansibility due to that the length and direction of each supporting strip can be flexibly adjusted through corresponding long circular grooves, particular suitability for the isolating and supporting operation of multiple high-voltage cables, and light weight, high strength and corrosion resistance due to that an aluminum magnesium alloy is adopted as the material, suitability for an outdoor high-altitude operation, and long service life.

Description

Technical field [0001] The invention relates to a power transmission device, in particular to a high-voltage cable isolation support. Background technique [0002] For high-voltage transmission lines, it is necessary to limit the distance between cables according to the size of the transmission voltage to prevent arc discharge and affect the safety of power transmission. The existing cable isolator is usually a hexagonal clip, which has a completely fixed size, poor flexibility, limited application range, poor material compression and corrosion resistance, and is easy to aging and deform. [0003] The patent application number 201510222450.X discloses a multi-purpose high-voltage cable isolator. There are two shortcomings in use. One is that the connection adjustment parts are not conducive to quick installation and adjustment, and the other is the semi-open "C" shape. The fixed clamp ring is not conducive to installing and fixing the isolation cable, and the cable is easy to deta...
