The role of rotating the cross arm is that when the line conductor (ground) wire is broken, the shear bolt of the cross arm is cut off, and the cross arm rotates 90 ° around the pole, so as to reduce the torque of the conductor on the cross arm and pole, so that the cross arm and pole will not be damaged, which is convenient for emergency repair.
