Four-line angle iron cross arm

Abstract

The present invention discloses a four-line angle iron cross arm. The four-line angle iron cross arm comprises a four-line angle iron cross arm body. The four-line angle iron cross arm body comprises a horizontal plate and an upright plate. Mounting holes for mounting porcelain pots are formed in the upright plate. The four-line angle iron cross arm is characterized in that two triangular iron plates are fixedly mounted on the horizontal plate; and the triangular iron plates are symmetrically distributed on the horizontal plate. The length of the triangular iron plates is equal to the width of the horizontal plate. When the four-line angle iron cross arm of the invention is used, the two triangular iron plates symmetrically distributed on the horizontal plate contact with a pole, so that the four-line angle iron cross arm can be more stable; and the length of the triangular iron plates is equal to the width of the horizontal plate, so that the contact surfaces of the triangular iron plates and the pole can be larger, and therefore, the four-line angle iron cross arm can be mounted on the pole more stably.

Description

technical field [0001] The technology relates to a cross arm installed on a utility pole for supporting electric wires, in particular to a four-wire angle iron cross arm. Background technique [0002] On an ordinary pole, the triangle iron on the pole is called a cross arm, which is used to fix the porcelain pot. Now there are more ultra-high-voltage transmission lines, and the poles are getting higher and higher. The top is no longer a triangle iron, but a horizontal iron frame to support overhead wires. Now some people also call this horizontal frame a cross arm, also Angled iron crossarm. The crossarm is an important part of the pole tower. Its function is to install insulators and fittings to support wires and lightning conductors, and to keep them at a certain safe distance according to regulations. According to the purpose, the cross arm can be divided into: straight line cross arm; corner cross arm; tension cross arm. According to the material, it can be divided in...

AI Technical Summary

Problems solved by technology

With the increase of the load on the angle iron cross-arm, coupled with the influence of the wind, the angle iron cross-arm is easy to shake relative to the utility pole, which will lead to loosening after a long time and endanger the safety of the transmission line
