The cross arm of the power transmission line is a special steel structure designed to hold the power line wires on the pole. Cross arm is installed on poles of both round and square cross-section with fastening by a clamp/pole strap.

Considering insulating design of the cross arms for the poles, it becomes possible to fix completely the cable to the tower body and it increases the overall span, and the height of the tower body does not change. The quality of the metal products used to perform the installation of an overhead power line directly affects its reliability and durability.
