UltraVac® Solid Dielectric Vacuum Capacitor Switches

UltraVac® Solid Dielectric Vacuum Capacitor Switches

UltraVac® Vacuum Switches

The UltraVac® family of vacuum capacitor switches is designed to fit a wide variety of capacitor switching applications. The long life vacuum interrupter combined with solid-dielectric insulation means many years of maintenance free switching. The UltraVac is designed for 110kV, 125kV, and 150kV BIL applications with a current rating of 200A; 400A rating options are also available. A choice of motor or solenoid operator provides an easy upgrade path when replacing existing capacitor switches. While the motor operated switches provide reliable, time proven, low energy switching, the solenoid operated switches provide fast simultaneous switching for applications where 3-single pole switches are required to operate simultaneously.

UltraVac switches from Trinetics set the standard for flexibility, durability, and reliability. With high dielectric strength, easy installation, and proven performance beyond ANSI standards, UltraVac switches are ideal for demanding, long-life applications.

Key features of the UltraVac vacuum switches include:

  • 15kV, 25kV, and 35kV
  • 200A & 400A ratings
  • Best-in-class C2 restrike rating
  • V-bushing design with uniform terminal height
  • Optional compact configuration for limited space applications
  • Manual open/close operation  
  • Maintenance-free operation

      30,000 open/close cycle mechanism for motor-operated switches
      50,000 open/close cycle mechanism for solenoid-operated switches

The UltraVac vacuum switch is a solid dielectric, single pole device designed in conformance with ANSI C37.66. The switch is constructed using a high performance vacuum interrupter inside a cycloaliphatic epoxy resin pole. UltraVac switches may be used to switch capacitor banks, to control lighting circuits, and to sectionalize power.
