various production / whosale models / support customization
ELECTRICAL CROSS ARM
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;
Angle of cross arm, except under vertical and horizontal load of the wire will also bear big unilateral wire tension. According to the force of the cross arm, the straight rod or 15 Angle pole adopts single cross arm, under the corner at the corner of 15 degrees above rod, tension rod, terminal rod, branch rod with double cross arm. Cross arm general installation from the peak of 300 mm, straight cross arm should be installed in the side, branch Angle pole, pole terminal, rod cross arm should be installed in the thread side.
