Electric line fitting wire cross arm

Abstract

The invention relates to an electric line fitting wire cross arm comprising cross arm assemblies, reinforcing rods, a locating frame and fixing devices. The reinforcing rods are connected between thecross arm assemblies in a clamped manner. The reinforcing rods are in bilateral symmetry. The locating frame is arranged in the middle of the cross arm assemblies. The fixing devices are installed inthe middle of the back ends of the cross arm assemblies. The electric line fitting wire cross arm can solve the problem that since most of the cross arms erected on the same pole are identical in specification, the longitudinal positions of the wires erected on the upper side and the lower side are located on the same plane, considering that most of the electric wires on the cross arms are erectedoutdoors, when outdoor wind is strong and excessive electric wires are erected, the wires erected on the upper side and the lower side are prone to make contact and generate interference, no connection exists between the existing cross arms, the single cross arm is poor in wind resistance when the wind is strong, and the number of insulators installed on each single cross is certain and cannot beincreased.

Description

technical field [0001] The invention relates to the field of power cross-arms, in particular to a wire cross-arm for power line accessories. Background technique [0002] The power cross-arm is the angle iron fixed horizontally on the top of the utility pole. It is used to install insulators and fittings to support the wires and lightning conductors and keep them at a certain safe distance according to the regulations. Most of the existing cross-arms are designed as traditional straight ones. Pole shape, and multiple power cross-arms are installed vertically on the same pole at the same time. This installation method often has the following problems: [0003] 1. Since most of the crossarms erected on the same utility pole are crossarms of the same specification, the longitudinal positions of the wires erected up and down are on the same plane. Since the wires on the crossarms are mostly erected outdoors, when the outdoor wind is strong, at the same time When too many wires ...

AI Technical Summary

Problems solved by technology

[0003] 1. Since most of the crossarms erected on the same utility pole are crossarms of the same specification, the longitudinal positions of the wires erected up and down are on the same plane. Since the wires on the crossarms are mostly erected outdoors, when the outdoor wind is strong, at the same time When too many wires are erected, it is easy to cause interference between the wires arranged up and down; 2. There is no connection between the existing cross-arms, and a single cross-arm has poor wind resistance in the case of large winds, and The number of insulators installed on a single cross-arm is certain and cannot be increased
