Tension Cross Arm
PRODUCT INFORMATION
Straight cross arm: only considered in normal without bolt, under vertical load and horizontal load of the wire;
Tension cross arm: conductor under vertical and horizontal load, the poor will also bear wire pulling force;
The cross arm is an important part of the tower. Its function is to install insulators and fittings to support conductors and lightning wires, and keep them at a certain safe distance according to regulations.
