Oil-Immersed Transformers

S13 Oil-Immersed Distribution Transformer

Also known as: S13 Distribution Transformer; Sealed Oil-Immersed Transformer

The S13 oil-immersed distribution transformer is developed as an improved low-loss alternative to earlier conventional distribution-transformer series.

Final voltage, capacity, losses, impedance, accessories, dimensions and applicable standards are confirmed according to the project specification and quotation.
Product overview

Design and operating characteristics

Its core and winding structures are optimized to reduce no-load losses, operating noise and temperature rise while maintaining reliable insulation and mechanical performance. The fully sealed corrugated oil tank accommodates oil-volume changes during operation and helps reduce contact between the transformer oil and external air.

The S13 series provides a mature and cost-effective solution for general medium-voltage distribution applications.
