Oil-filled transformers use liquids for cooling, making them highly suitable for outdoor applications. They are more efficient, have longer service lives, and feature more reliable overload capabilities.Transformer is isolated from the rest of the air, to prevent and slow the deterioration of oil and insulation aging, enhance the operation reliability.

Features:
The company produces three-phase oil-immersed distribution transformers with high efficiency and low loss, which can save a lot of power consumption and operating costs.

The transformer body adopts a new insulation structure, which improves the short-circuit resistance.

The transformer core is made of high-quality cold-rolled silicon steel sheets with high magnetic conductivity.

The transformer core consists of high/low-voltage windings are selected high-quality oxygen-free copper wire, and multi-layer cylindrical structure.

All fasteners with special anti-loosening treatment.

The oil tank is corrugated structure, the cover and the edge of the box are completely welded or fastened with bolts in two types, which fundamentally prolongs the service life of the transformer oil and insulating materials.
