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.
