Support rack for power transmission line of power system

Abstract

The invention discloses a support frame for a transmission line of an electric power system, which includes an arm frame, the arm frame is a U-shaped groove, the arm frame is fixed on the wall, bolt holes are arranged on both sides of the arm frame, and the support seat is fixed by fixing bolts On the arm frame, the support seat is a triangle; the lower end of the support seat is a rib of the triangle, and the upper end is a surface; the upper end surface of the support seat is provided with an arc-shaped wire groove guide rail, and the wire groove guide rail is provided with a wire groove. The length of the trunking is 0.5-1m, and the trunking is made of plastic. When in use, the ledge is installed on the wall, the cable can be laid after the supporting frame is installed, and the cable can be placed in the wire groove after the cable is laid. The support length is increased, and the use of the support frame of the present invention can prevent the cable from bending without increasing the installation support point, which solves the problem of cable bending caused by point support when the cable is laid in the tunnel, and the increase in the use length wastes the cable. If support points are added, it will be time-consuming and labor-intensive.

Description

technical field [0001] The invention relates to cable wiring equipment, in particular to a support frame for power system transmission lines. Background technique [0002] In the power system, its cable wiring is divided into high-altitude wiring, underground pipeline wiring, and tunnel wall wiring. In tunnel wiring, the support frame is generally used to assume the cables on the tunnel wall. When wiring, because the support frame is a point Therefore, when the cable is laid, the cable between the two support points is bent downward. After bending, the use length of the cable will be increased and the cable will be wasted. If the cable is not bent, the support point will be increased. Dense, so that the installation holes are added on the tunnel wall, and the drilling and installation are time-consuming and labor-intensive due to the dense addition of points. Contents of the invention [0003] The technical problem to be solved by the present invention is that when cables...

Problems solved by technology

[0003] The technical problem to be solved by the present invention is that when cables are laid in tunnels, the cable is bent due to point support, and the length of use is increased to waste cables. If support points are added, it will consume time and effort. The purpose is to provide support for power system transmission lines When laying cables in the tunnel, the cable is bent due to point support, and the length of use is increased to waste cables. If additional support points are added, it will consume time and energy.
