Reliable, Resilient, Revolutionary

G&W Electric’s Viper-HV 72.5KV recloser is designed to provide overcurrent protection through fault isolation and automatic restoration for temporary faults on overhead sub-transmission lines.

  • Innovative 3-in-1 Device. This revolutionary solution incorporates reclosing technology, current transformers, and voltage sensors in a single space-saving design.
  • Automation Ready. Simplifying conversion for any future requirements, the Viper-HV provides faster fault isolation, restoration, and reconfiguration capability.
  • Design Flexibility. With modular and flexible mounting configurations and different relay options, it provides additional savings by not having a foundation in a fenced substation and control house.
