Joslyn Hi-Voltage Electric Arc Furnace Switches

Joslyn Hi-Voltage Electric Arc Furnace Switches

ABB engineers worked closely with electric arc furnace manufacturers to develop the Joslyn Hi-Voltage Transmaster VBT electric arc furnace switch, a heavy-duty vacuum switch designed to deliver maintenance free switching of electric furnaces.

Benefits

  • Long life product for electric furnaces
     
  • Long, maintenance-free life under demanding conditions, designed for 100,000 operations
     
  • No oil or gas used for interruption or insulation
     
  • Safe – no visible or hazardous arcing and no hot exhaust or ionized gas dissemination
     
  • Vacuum interrupter condition can be determined by a high-potential withstand test quickly
     
  • Lightweight modular design – no special foundations or costly support required
     
  • Removable fuses provide protection
     
  • Vacuum contacts withstand excessive overloads and system short circuits at any power factor
