ABSTRACT:
A spacer-twister device for securing to first and second conductors includes an elongate insulating member having first and second ends. A first clamp is rotatably coupled to the first end of the insulating member by a first joint for gripping the first conductor. A second clamp is rotatably coupled to the second end of the insulating member by a second joint for gripping the second conductor. The insulating member provides proper spacing between the first and second conductors with the first and second joints allowing twisting of the first and second conductors. In turn, the twisting prevents or dampens galloping of the conductors.
