Medium Voltage Loadbank

Medium Voltage Load Bank



Medium Voltage load banks (model LBM) operate at a maximum voltage of 15kV. LBM load banks are NEMA 3R, free standing constructed of galvanized steel and designed for outdoor operation. Thomson’s unique direct-connect design utilizes resistor frames constructed to operate at medium voltage eliminating the need for transformers. Providing a true direct-connect solution with the following advantages:

  • Increased capacity
  • Fewer overcurrent protection devices
  • Increased service life
  • Reduced maintenance
  • Lower capital costs
  • Lower operating cost
