Description

The Functionality of Breaker Gear at Much Lower Cost

System VI Switchgear, available in ratings through 38 kV, combines the innovative features of Vista® Underground Distribution Switchgear (see pages 44 through 47) with the versatility of S&C Metal-Enclosed Switchgear (see pages 48 through 51). It’s offered in manual, remote supervisory, and source-transfer models.

System VI Switchgear features a modular arrangement of Vista UDS sections. Each section includes 600-ampere load-interrupter switches and fault interrupters, sealed in an SF6-insulated, elbow-connected tank. Using gas-tight air-insulated bushings on one or both sides of the tank, multiple sections are joined together with air-insulated transition bays, which can be furnished with metering transformers and other equipment. Transition bays can also be used to connect a System VI Switchgear lineup to S&C Custom Metal-Enclosed Switchgear or to a transformer.

All the Advantages of Vista UDS

Like Vista UDS, System VI Switchgear offers:

  • Compact, low-profile design. Even at 34.5 kV, System VI gear can be as little as 37 inches tall. And

    System VI gear has a significantly smaller footprint than breaker gear.

  • Single- or three-phase protection through 900 amperes continuous with resettable vacuum fault interrupters.
  • No exposure to energized cables and elbows during routine operations. All switching and grounding operations—even voltage testing—can be performed quickly and easily by a single person, from the operating panel.
  • Microprocessor-based overcurrent control provides advanced, flexible protection. External-trip option allows fault interrupters to be tripped from transformer-secondary or sudden-pressure relays.
  • It’s affordable. System VI gear offers significant savings over breaker gear.
