G&W's Viper-HV is the market’s first high-voltage pole top recloser that supports faster overcurrent protection through fault isolation and automatic restoration for temporary faults on overhead sub-transmission lines.

Uniquely designed as a self-contained system featuring three-in-one capabilities of a recloser, CTs, and integrated internal voltage sensors, the Viper-HV provides utilities improved performance on a pole to automatically clear any temporary faults and isolate only that section of the grid to protect additional lines from going down and preventing an entire region from losing power.

The Viper-HV offers utilities installation flexibility through a variety of configurations, including phase-over-phase and cross-arm versions to match existing line infrastructure. G&W Electric offers site-ready designs with pre-installed accessories and flexible solutions tailored to meet environmental challenges.
