Product presentation
The S11-20KV series three-phase oil-immersed non-excitation voltage regulation distribution transformer produced by the company has the characteristics 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.

The transformer body adopts a new type of insulation structure, which improves the short-circuit resistance;
The transformer core is made of high quality cold rolled silicon steel sheet;
The high and low voltage windings of the transformer are made of high quality oxygen-free copper wire, and multi-layer cylinder structure;
All fasteners of the transformer are treated with special anti-loose treatment;
The transformer oil tank is a corrugated structure, and the cover and edge of the box are completely welded or bolted, 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.
