The cross arm is the angle iron fixed horizontally on the top of the pole. It is an important component of the pole tower. It is used to install insulators and hardware to support the conductors and lightning conductors, and keep them at a certain safety distance as required. When supporting the wires overhead, the box-type power pole tower cross arm structure is needed. In actual use, the existing box-type power pole tower cross arm structure has many defects, such as the power pole tower cross arm support structure is relatively simple, so that some positions on the outside of the cross arm cannot get support force, which easily causes the outside of the cross arm to bend downward, and it is not convenient to adjust the installation position of the wires on the cross arm.
