The Extension Arm is designed for use on voltages up to and including 15 kV where reconductoring or insulator replacement is necessary.

The Extension Arm is suspended under the crossarm by brackets, in a way so that approximately 3/4 of its length exceeds the crossarm length, to enable the conductor to be removed from the original crossarm and placed in the wireholder mounted on the Extension Arm.
