Product Description

Product Description

The iron core of S11-M series low loss energy-saving transformer produced by our company adopts laminated structure. This product is based on fully absorbing the advanced technology and process of domestic oil immersed transformer, combined with the technical level of our company, putting the reliability of the product in the first place, at the same time, the no-load loss and no-load current of the product are greatly reduced.

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.
 

Features

1. The coil adopts a low axial short-circuit force structure. When the transformer is short-circuited, it can greatly reduce the axial short-circuit force and greatly improve the ability of withstanding short-circuit.
2. All the bolts and nuts on the cover surface are made of 304 stainless steel, which enhances the rust prevention ability of the transformer.
3. Each sealing rubber ring adopts the best rubber material in China, which greatly prolongs the service life of the sealing rubber ring.
4. The transformer body adopts a high-reliability support structure to ensure reliable compression of the upper and lower parts of the coil. The entire body structure improves the ability of withstanding short-circuited.
5. This not only reduces the no-load loss of the transformer, but also ensures that the core flux is not saturated when the transformer is operating under voltage, so that the third harmonic of the transformer is small.
