- AC withstand 34/40/50kV
Overview
The R-Stack is an innovative design combining a Deadbreak Connecting Plug with a Deadbreak Elbow in one premolded, factory-tested composite. Installation force drops to about 25 lbs versus 100 lbs for a standard plug, and stack height is reduced by 4 inches per two elbows. It is well suited to tight cabinets and manholes.
