TMC Transformers

SPECIFICATION

Cast Resin Technology- Key Points & Advantages

• Generally MV insulation system
  <52kV and ratings <25MVA
• Combination of Cast Resin and Foil winding offers
  the ultimate in terms of dielectric performance
  and short circuit withstand.
• Winding in either Aluminium or Copper
  – No technical difference.
• Available in Class “F” (155°) or Class “H” (180°)
  resin systems.
• Axial air cooling channels ‘cast’ into coil for improved cooling and economy for ratings > 5MVA
• Selected LV applications
  for Heavy Environmental pollution

VPI Technology- Key Points & Advantages

• Generally LV insulation system
  < 7.2kV and ratings < 20MVA
• Vacuum Pressure Impregnation
• Processed in vacuum chamber – Resin initially introduced under vacuum and then placed under positive pressure to improve impregnation
• Class “H” (180°) thermal class material and axial cooling channels provide economical solution.
• Specialist Application Designs < 24kV
• Winding in either Aluminium or Copper
  – No technical difference.
• Perfect solution for low voltage transformers
  and inductors
• Flame Retardant materials
