Cast Resin Transformer

 

Short Circuit Strength
  • Vacuum-cast with epoxy resin with excellent electrical and mechanical strength
Easy to Maintain
  • No oil exchange and firefighting equipment
Overload Tolerance
  • Excellent overload tolerance compared to the oil immersed type transformer
Eco-friendly
  • No environmental contamination due to oil spills
Suitable for Power Supply to Equipment with Rapid Changing Loads
Humidity Resistance
  • Coils are vacuum-molded to prevent entry of moisture
Non-combustibility
  • Uses non-combustible epoxy resin to prevent fires
Excellent Impulse Voltage Strength
