LRTP Reducer Kit

Ordering Information

The Hubbell Power Systems 600 A 15 or 25kV rated LRTP Deadbreak Termination System is designed to connect 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 LRTP system uses a threaded compression lug allowing the LRTP to be threaded into the T-body forming an integral termination system. The T-body can be ordered with or without a capacitive test point.

The LRTP system is ideal for applications where the termination will be moved to achieve a visible break and ground. The integral termination system, T-body and LRTP as one unit, makes it easier to install and remove from the mating bushing interface.

The 200-amp loadbreak interface can be either 15kV or 25kV rated. This interface allows for live test, phasing and visible ground. In addition, it can be used to add a tap, or install an Arrester Elbow to protect your UD system from voltage surges.
