Premium Efficiency Oil Type Distribution Transformer, Efficiency Level 2

S20 series premium efficiency oil lmmersed transformers are designed with a rated capacity ranging from 30KVA to 2500KVA, suitable for power systems operating at voltages between 6KV and 11KV. Premium efficiency oil lmmersed transformers serve as critical equipment in small and medium-sized substations. The S20 series utilizes high-grade oriented silicon steel sheets as core materials and high-conductivity wires for the electromagnetic coils, resulting in a 30% reduction in no-load losses, a 20% reduction in load losses, and a 25% decrease in total commodity losses. This enhances environmental protection, energy efficiency, and economic benefits during network operation.

Key Features

1. Energy Efficiency

Optimized structural design reduces core and coil losses, enhancing energy conversion efficiency while lowering overall operational energy consumption.

2. Low Operational Loss

Constructed with premium silicon steel and advanced processing techniques to minimize both no-load and load losses, contributing to lower system operating costs.

3. Superior Heat Dissipation

Utilizes transformer oil for cooling, enabling effective heat dispersion through natural convection or forced oil circulation, which ensures stable performance under heavy loads and extends service life.

4. Eco-Friendly Design

Meets stringent domestic and international standards for energy conservation and environmental protection, helping to reduce carbon emissions and making it ideal for green energy applications.

5. High Safety and Reliability

Engineered with high-strength insulation materials and precise manufacturing processes to guarantee stable and secure operation even in demanding grid conditions.

· Excellent insulation: The premium efficiency oil lmmersed transformer uses high-quality copper wire and high-grade ferrite core, oil is filled as the insulating medium between the iron core and inductor coil. This kind of insulation layer is more reliable than other insulation methods. The oil of oil-immersed transformer cannot only act as an insulating layer, but also play a cooling effect, so that the transformer won’t have too much heat or damage during its long-term work.

· Durable and cost-effective: S20 series oil-immersed power transformers have a long service life, which can generally exceed 40 years. Especially for the manufacturing enterprises and other applications, this type of transformers can be integrated into more harsh environments.

· Low loss: Compared with S13 transformer, the no-load is reduced by 15%, the load is reduced by 10%, S20 transformer saves 20% power than S13 every year.

· Low noise: S20 premium efficiency oil lmmersed transformers have low and stable noise of the stacker crane during working, while dry type transformers often produce noise, especially in high humidity environments.

· Small footprint: S20 series premium efficiency oil lmmersed transformer has better sealing, so its volume will be lower than the same capacity of dry type transformer, it is a better choice for some insufficient space.
