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.

Shengte's low-loss energy-saving transformer features a laminated iron core structure. Leveraging advanced technology and oil-immersed transformer processes, along with our technical expertise, we ensure product reliability, achieving significant reductions in no-load loss and no-load current.


Features:

1. Minimized Axial Short-Circuit Force Coil: Reduces axial short-circuit force, enhancing short-circuit resistance.

2. Robust Supporting Structure: Ensures reliable compression of coil parts, offering strong short-circuit resistance.

3. Low Magnetic Flux Density: Reduces no-load loss and prevents core magnetic flux saturation, minimizing harmonic distortion.

4. 304 Stainless Steel Hardware: Improves surface rust resistance of the transformer.

5. Premium Sealing Rubber Rings: Utilizing high-quality raw materials for sealing rubber extends the transformer's service life.

Our Advantages:

1. Superior Heat Dissipation and Structural Integrity: The spiral coil with longitudinal oil ducts offers excellent heat dissipation, low magnetic leakage, and high mechanical strength. The supporting structure enhances short-circuit withstand capability.

2. Efficient Iron Core: Composed of silicon steel sheets less than 0.35mm thick and with high magnetic conductivity, the core reduces no-load loss and current, improving efficiency.

3. High-Quality Insulation: Materials with high heat resistance withstand overvoltage and overcurrent, ensuring durability and reliability.

4. Superior Transformer Oil: Features low viscosity and excellent heat transfer and insulation properties, protecting the core and windings, reducing insulation material aging, and extending service life.

5. Durable Oil Tank: Made from high-quality cold-rolled steel plates, treated with de-oiling, rust removal, and phosphating, and coated with three-proof paint, enhancing reliability and reducing maintenance costs.

6. Effective Sealing Rings: High-quality rubber materials slow aging, isolate external air, and prevent oil leakage.
