Description

Technical Field

[0001] The utility model relates to the technical field of cross arms, in particular to a tension cross arm for a utility pole. Background Art

[0002] The function of the crossarm is to fix the angle iron horizontally on the top of the pole, with a porcelain bottle on it, which is used to support the overhead wires. The crossarm is an important component of the pole tower. Its function is to install insulators and hardware to support the conductors and lightning conductors, and to maintain a certain safety distance as required. It is a type of crossarm.

[0003] The connection method between the cross arm support and the electric pole in the prior art is relatively simple, lacking an effective triangular distribution support design, resulting in poor stability of the overall structure, making it difficult to withstand external force impacts under extreme weather conditions, which may affect the service life of the cable and the stability of power transmission. In addition, the cable support method is mostly fixed, which is difficult to effectively adjust according to the number and position of the cables, limiting the flexibility of on-site adjustment. Therefore, we propose a tension cross arm for electric poles. Utility Model Content
