Product Description

Product Description

Cutting-Edge Technology in Shengte Energy-Saving Transformers
Shengte's low-loss energy-saving transformer boasts an innovative laminated iron core structure. By incorporating advanced technology and oil-immersed transformer processes, combined with our technical prowess, we ensure product reliability, resulting in notable reductions in no-load loss and no-load current.

Features:

1. Low Axial Short-Circuit Force Coil: This design minimizes axial short-circuit force, enhancing the transformer's resistance to short circuits.
2. Highly Reliable Supporting Structure: Guarantees reliable compression of coil parts, providing strong short-circuit resistance.
3. Low Magnetic Flux Density Design: Reduces no-load loss and prevents core magnetic flux saturation, minimizing harmonic distortion.
4. 304 Stainless Steel Bolts and Nuts: Enhance rust resistance of the transformer's surface.
5. High-Quality Sealing Rubber Rings: Using the best raw materials for sealing rubber in China, we significantly extend the transformer's service life.

Our Advantages:

1. Excellent Heat Dissipation and Structural Integrity: The spiral coil with longitudinal oil ducts ensures superior heat dissipation, low magnetic leakage, and high mechanical strength. The supporting structure enhances short-circuit withstand capability.
2. Efficient Iron Core: The iron core, composed of stacked silicon steel sheets less than 0.35mm thick, has high magnetic conductivity, reducing no-load loss and current, improving efficiency.
3. High-Quality Insulation Materials: With high heat resistance, these materials 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.
