G&W Electric Introduces the World’s First Sub-Transmission Recloser


– Revolutionary turnkey solution for utilities to improve system reliability and grid resiliency

G&W Electric ( ), a global supplier of electric power equipment since 1905, today announced the launch of its Viper®-HV Recloser up to 72.5kV. The market’s first high-voltage pole top recloser supports faster overcurrent protection through fault isolation and automatic restoration for temporary faults on overhead sub-transmission lines.

“As we’ve seen recently, the fragile state of our nation’s electrical infrastructure has severe consequences to our safety and economy,” said John Mueller, chairman and owner of G&W Electric. “We are committed to partnering with utilities to identify vulnerabilities and deliver state-of-the-art solutions like the Viper-HV recloser for functionality right on the sub-transmission lines. Until today, that was only available by installing high-cost substations.”

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 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.

“In an effort to develop the grid of the future, the Viper-HV recloser also offers solutions that will help utilities reduce future cost such as maintenance, replacing equipment and outage penalties,” added Mueller.

Without the need for oil or gas, the Viper-HV reduces routine maintenance and improves personnel safety. Additionally, the vacuum interrupter and other energized parts are sealed within field proven solid-dielectric insulation, providing optimum operator safety and additional protection to discourage wildlife interference.
