Core Features

  1. Advanced Insulation & Safety

    • Cast Resin Dry Type Transformer coils are fully encapsulated in flame-retardant epoxy resin, ensuring non-flammable, explosion-proof, and pollution-free operation.

    • Self-extinguishing material complies with international fire safety standards.

  2. High Efficiency & Low Loss

    • Optimized core design using 45° fully oblique joint cold-rolled silicon steel sheets minimizes no-load loss and noise.

    • Multi-stage core stacking process reduces no-load current by 20% compared to traditional models.

  3. Robust Construction

    • Iron core surface sealed with insulating resin paint prevents rust and moisture ingress.

    • Reinforced mechanical structure enhances short-circuit resistance and longevity.

  4. Smart Temperature Control

    • Integrated intelligent system with over-temperature alarm, trip protection, and RS485 interface for remote monitoring.

    • Operates reliably at 150% rated load under forced air cooling.

  5. Maintenance-Free Operation

    • Resin insulation eliminates the need for oil, reducing upkeep costs.

    • Functions seamlessly in 100% humidity without pre-drying.
