Product Description

The S11-20KV series three-phase oil-immersed non-excitation voltage-regulating distribution transformer have the characteristic of high efficiency and low loss, which can save a lot of power consumption and operating costs, and has significant social benefits. It is a high-tech product promoted by the state.

1. The transformer body adopts a new insulation structure, which improves the short-circuit resistance.
2. The transformer core is made of high-quality cold-rolled silicon steel sheets with high magnetic conductivity.
3. The transformer core consists of high/low-voltage windings are selected high-quality oxygen-free copper wire, and multi-layer cylindrical structure. 4. All fasteners with special anti-loosening treatment.
5. 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.

The above standards are subject to the latest released information; Equipment requirements should be based on the corresponding latest national professional standards.
