S22-M-30-2500/10-NX1 oil immersed transformer

The new standard was officially implemented on June 1, 2021. All newly added transformers must meet the new energy efficiency requirements, with the minimum standard being the new third-level energy efficiency (S13 oil-immersed transformer).

1. The S22 transformer has excellent oil insulation and thermal conductivity, while the transformer oil is cost-effective.

2. It can address large-capacity heat dissipation and high-voltage insulation issues.

3. The S22 oil-immersed transformer is fully sealed, effectively preventing insulation oxidation and aging.

4. The S22 transformer core uses higher-quality silicon steel sheets, with increased core cross-sectional area, resulting in higher energy efficiency. The S22-630kVA saves over ten thousand kWh per year compared to S13-630kVA.
