The 10kV S13 (S20/S22)-M series oil-immersed distribution transformer is an upgraded generation of high-efficiency and low-loss transformers designed to meet modern power distribution requirements.

Compared with the S11 series, the S13 series features lower no-load loss, improved energy efficiency, and reduced operating costs, making it an ideal solution for energy-saving power systems.

The core is manufactured using high-quality cold-rolled grain-oriented silicon steel with a 45° fully mitered joint structure, ensuring excellent magnetic performance, reduced losses, and low noise operation.

This transformer is widely applied in:

• Stedelijke en landelijke stroomdistributienetwerken
• Industriële en mijnbouwbedrijven
• Power grid renovation and upgrading projects
• Compacte geprefabriceerde onderstations (pakketonderstations)
