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.

KNOWLEDGE BASE --- Main Reasons for Deformation of Transformer Coils
With the continuous development of the power system, the transformer plays an increasingly important role as a key equipment in the power system. The safe operation of electrical isolation transformer is directly related to the reliability of the entire power system.
Transformer coils deformation refers to the axial and amplitude dimensional changes, body displacement and coil distortion that occur after the coils are stressed.
There are two main reasons for the deformation of transformer coils.
One is that the transformer is unavoidably affected by external short-circuit faults during operation.
The other is that the transformer is accidentally collided during transportation and hoisting.
