Features
  • Silicon Steel Sheet: New cold rolled silicon steel sheet, 0.27mm, 0.30mm, 0.35mm of thickness, excellent performance.
  • Terminal Block: High quality terminal block, excellent temperature resistance, pressure resistance and flame retardancy for small power. For high power, made of quality copper material, with good electrical conductivity, high temperature resistance, not easy to burn out the equipment when short circuit happens.
  • Enameled Wires: H class enamelled copper/aluminum wires, temperature resistance180℃, winded tightly and uniformly, no insulating layer, high heat dissipation, service life ≥35 years.
  • Bobbin: Made of nylon, high temperature resistance, great flame retardancy. The high power transformer with frameless design has ventilation slots between the coils for smooth air flows which reduce temperature of coils.
  • Insulation Process: The whole dry type isolation transformer adopts H-class vacuum impregnated insulation, temperature resistance of 180°C, lower noise, better insulation and is anti-rust and anti-corrosion.
