Viper-HV - 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.
FEATURES & BENEFITS
- Maintenance Free - Eliminate routine maintenance and improve personnel safety because the Viper-HV requires no oil or gas.
- Enhanced Reliability - Current carrying is path protected from the environment with magnetic actuator connected to vacuum bottle, so no gears or motors are impacted by outside elements.
- Compact 3-in-1 Device - Features a recloser, CTs and Voltage Sensors in a single space-saving design.
- Automation Ready - Simplifies conversion for any future requirements; provides faster fault isolation, restoration and reconfiguration capability.
- Pole Top Design - Gain more design flexibility and cost savings by eliminating foundation in fenced substation and control house.
- Configuration Flexibility - Adapts to the pole construction and relay selection that best matches your requirements with modular and flexible mounting configurations and different relay options.
- Operator Safety - Vacuum interrupter and all energized parts are sealed within field-proven solid-dielectric insulation, providing optimum operator safety and protection to prevent exposure to environment and wildlife.
- Plug-and-Play Installation - Includes protection relay in an outdoor control with connectorised control cable on both ends.
