Product Description

Oil immersed transformer use oil as the main insulation medium and rely on oil as the cooling medium. It adopts a sealed structure to completely isolate the transformer oil from the surrounding air, making the operation of the transformer safer, more reliable, and easier to maintain.

🚀 Key Features

  • High-voltage and low-voltage windings generally adopt a cylindrical structure for balanced ampere turns distribution.
  • The coil and core undergo vacuum drying; transformer oil is filtered and injected via a vacuum process.
  • Corrugated plates in the oil tank compensate for volume changes caused by temperature fluctuations.
Transformer Description
Our Advantages
  • Optimized Dissipation: Spiral coil with longitudinal oil duct ensures excellent heat dissipation and high mechanical strength.
  • Low Loss Core: Stacked structure with high magnetic conductivity silicon steel sheets reduces no-load loss and current.
  • Superior Insulation: Materials with high heat resistance withstand overvoltage and overcurrent during operation.
  • Enhanced Protection: Low viscosity oil with good heat transfer effectively protects the core and winding from aging.
  • Durable Construction: Corrugated oil tanks are treated with deoiling, rust removal, and three-proof paint for high durability.
