Embodiment Construction

[0011] Such as figure 1 , 2 , 3, one end of the lower cross arm 1 of the present invention is connected together with the inner side of one end of the upper cross arm 3 through the reinforcement plate 2, and the reinforcement plate 2 covers the lower side of the lower cross arm 1 and the upper cross arm 3, and the The other end of the upper cross arm 3 is bent, and two fixing holes 4 are respectively provided in the middle parts of the lower cross arm 1 and the upper cross arm 3, and the U-shaped lifting rings 5 ​​are passed through one end of the lower cross arm 1 and the two ends of the upper cross arm 3 respectively. An insulator 6 is provided. Through the above settings, the present invention is fixed on the top of the pole tower 7 by U-shaped bolts, forming a triangle with the shaft of the pole tower 7, and the stability is firmer, and the wire is suspended on the insulator 6 to realize overhead of the wire. The invention integrates the two layers of cross arms, and the...

Abstract

The invention discloses an energy-saving electric transmission line wire cross arm which is characterized in that one end of a lower cross arm body is connected with the inner side of one end of an upper cross arm body through a reinforcing plate, the reinforcing plate covers the lower cross arm body and the lower side of the upper cross arm body, the other end of the upper cross arm body is bent, the middle of the lower cross arm body and the middle of the upper cross arm body are respectively provided with two fixing holes, and one end of the lower cross arm body and the two ends of the upper cross arm body are provided with insulators through U-shaped hanging rings respectively. By means of the arrangement, the energy-saving electric transmission line wire cross arm is installed at the top end of an electric tower, three-dimensional space is ingeniously used for arranging a line, the height of the tower can be effectively reduced, the weight of the cross arm can be reduced, on the premise that the tower is not replaced, the problem that the crossing spanning distance of an original line is insufficient is solved, the aim of arranging the wire cross arm of the electric tower is achieved, and the line operation cost is effectively saved.

Description

technical field [0001] The invention relates to the technical field of power poles and towers, in particular to an energy-saving power transmission line conductor crossarm used on power poles and towers. Background technique [0002] 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. Existing transmission line towers are generally arranged in triangular wires and installed on a cross-arm, which requires additional devices such as tie rods and struts, which not only increases the height of the tower, but also increases the weight of the cross-arm, and the cost of the tower also increases. For towers with limited tower heights, the crossing distance of conductors is insufficient, resulting in hidden dangers in the line. Contents of the invention [0003] The object of the present invention is to provide an ener...
