Oil Immersed Transformer Description

Oil Immersed Transformer is a piece of power equipment cooled and insulated by insulating oil, typically used in high-power transmission and distribution systems. The insulating oil not only helps with thermal dissipation and temperature regulation, but also enhances the transformer’s electrical insulation performance and dielectric strength, thereby extending the power equipment’s lifespan and improving its operational reliability in high-voltage systems.

We specially designed the S11 series 20kV power transformer to meet the demands for high efficiency, energy conservation, low noise, and high reliability. Power companies and industrial users widely apply it in urban and rural distribution networks, industrial parks, and various high-load operation scenarios.This series of transformers is based on advanced technology and high-quality materials, featuring outstanding electrical performance and operational stability.

1. Winding structure:

Our transformers adopt multi-layer cylindrical winding structures that enhance impact distribution, reduce magnetic leakage, and provide high mechanical strength and strong short-circuit resistance.

2. Excellent core design:

We optimize the core design to significantly reduce no-load losses, minimize no-load current, and ensure efficient operation.

3. Strengthen fastening and prevent loosening:

We apply precise fastening techniques and use self-locking anti-loosening nuts to ensure stability during transportation.

To enhance durability, our team adopts a non-suspended center structure that effectively absorbs vibration.

Meanwhile, the fastening components consistently ensure long-term operational integrity, even under demanding conditions.

4. Advanced vacuum processing:

We vacuum-dry the coils and cores and perform vacuum oil injection with filtration to minimize internal moisture, thereby improving transformer performance and extending service life.

5. Ingenious fuel tank design:

We use corrugated plates with a breathing function in the oil tank to compensate for oil volume changes caused by temperature fluctuations. This design eliminates the need for an oil conservator and effectively lowers the transformer’s height.
