Product Description

Product Description

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. The high-voltage and low-voltage winding of oil immersed transformer generally adopt a cylindrical structure, which ensures a balanced distribution of ampere turns.

2. The coil and core are vacuum dried, and the transformer oil is filtered and injected through a vacuum process.

3. The oil tank adopts corrugated plates, which can compensate for the volume change of oil caused by temperature changes.

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.
