Deadbreak Insulating Plug & Cap

15/25kV Deadbreak Insulating Plug & Cap

The Deadbreak Insulating Plug is used to insulate and plug the open end of a Deadbreak Elbow or Bushing Extender.  The insulated plug features a 1″ hex nut for de-energized installation.  The hex nut also functions as a capacitive test point for voltage detection.  The P625HIP meets all requirements of IEEE 386 and is supplied with an EPDM rubber cap for shielding and sealing purposes.
