ETP Reducer Kit

Ordering Information

The Hubbell Power Systems 600 A 15 or 25kV rated ETP (Elbow Tap Plug) Deadbreak Termination System is designed to terminate medium voltage UD cable to switchgear, transformers, sectionalizing cabinets and UD vault applications. It is fully compliant with IEEE-386 Standard and mates with bushing components that also comply with the IEEE-386 Standard. The ETP system is comprised of a standard 600 amp t-body, an unthreaded compression lug, a cable adapter and the ETP. The t-body can be ordered with or without a capacitive test point.

The ETP system is ideal for applications where a 200-amp tap is desired for test or ground purposes, with the visible open achieved through use of an internal switch and a viewing window. The ETP is also ideal for adding a 200 amp tap to an existing 600 amp elbow termination.

The 200-amp loadbreak interface can be either 15kV or 25kV rated. This interface allows for live test, visible ground, addition of a 200 amp tap, or installation of an arrester elbow to protect your UD system from voltage surges.
