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.

The iron core of Shengte low loss energy-saving transformer features a laminated structure. Leveraging advanced technology and oil-immersed transformer processes, combined with our company's technical expertise, we prioritize product reliability. This results in significant reductions in both no-load loss and no-load current.

Features:

1.Low Axial Short-Circuit Force Coil: This structure minimizes the axial short-circuit force, enhancing the transformer's ability to withstand short-circuits.

2. Highly Reliable Supporting Structure: Ensures reliable compression of the upper and lower coil parts, providing strong short-circuit resistance.  

3. Low Magnetic Flux Density Design: Reduces transformer no-load loss and ensures the core magnetic flux remains unsaturated during operation, minimizing third harmonic distortion.

4. 304 Stainless Steel Bolts and Nuts: Enhances the transformer surface's rust resistance.

5. High-Quality Sealing Rubber Rings: By adopting the finest raw materials for sealing rubber in China, we significantly extend the service life of the transformer.

Our Advantages:

1. Excellent Heat Dissipation and Structural Integrity: The spiral coil with longitudinal oil ducts offers superior heat dissipation, low magnetic leakage, and high mechanical strength. Additionally, the reliable supporting structure significantly enhances the transformer's ability to withstand short circuits.  

2. Efficient Iron Core: The iron core is composed of stacked silicon steel sheets with a thickness of less than 0.35mm and high magnetic conductivity. This design reduces no-load loss and no-load current, improving overall efficiency.

3. High-Quality Insulation Materials: The insulation materials used have high heat resistance, allowing the transformer to withstand overvoltage and overcurrent during operation, ensuring longevity and reliability.

4. Superior Transformer Oil: The transformer oil features low viscosity and excellent heat transfer and insulation properties. It effectively protects the iron core and windings, reduces the aging of insulation materials, and extends the transformer's service life.

5. Durable and Reliable Oil Tank: The corrugated oil tank is made from high-quality cold-rolled steel plates on a dedicated production line. Its surface undergoes de-oiling, rust removal, and phosphating before being coated with a three-proof (rainproof, moisture-proof, and salt spray-proof) paint. This treatment enhances operational reliability and durability while reducing maintenance costs.

6.Effective Sealing Rings: The sealing rings are made from high-quality rubber materials, which effectively slow down the aging process, isolate external air, and prevent transformer oil leakage.
