10–35 kV Oil-Immersed Transformers
S13-M Series Three-Phase Oil-Immersed Fully Sealed Distribution Transformer. Unlike conventional oil-immersed transformers, this model eliminates the conservator tank and relies instead on corrugated-fin radiators integrated into the transformer tank for heat dissipation and cooling, while the elastic expansion and contraction of the radiator compensates for changes in oil volume. The product features a compact footprint and an aesthetically pleasing appearance, enabling core-free lifting, maintenance-free operation, and low noise levels.

10–35 kV Oil-Immersed Transformers
S13-M Series Three-Phase Oil-Immersed Fully Sealed Distribution Transformer. Unlike conventional oil-immersed transformers, this model eliminates the conservator tank and relies instead on corrugated-fin radiators integrated into the transformer tank for heat dissipation and cooling, while the elastic expansion and contraction of the radiator accommodate changes in oil volume. The product features a compact footprint and an aesthetically pleasing appearance, enabling core-free lifting, maintenance-free operation, and low noise levels.
Scope of Application: This series of products is suitable for 10 kV, 20 kV, and 35 kV transmission and distribution systems and can be used for power supply and lighting in residential areas, commercial districts, industrial and mining enterprises, and rural areas.
The low-voltage windings of the transformer are wound with copper foil or semi-rigid copper wire, enhancing the transformer’s ability to withstand short-circuit conditions.
The transformer connection group is configured as Dyn11 to reduce harmonic distortion in the power grid and improve power quality.
The fuel tank and lid feature a fully sealed design, extending service life and eliminating the need for maintenance.
The transformer employs vacuum oil impregnation, which completely eliminates air bubbles within the windings and ensures stable insulation performance.
Each transformer undergoes factory acceptance testing before shipment to ensure safe and reliable operation.
Rated voltage: 10 kV, 20 kV, 35 kV
Rated capacity: 30–2,500 kVA.
