The SZ11-35KV series three-phase oil-immersed non-excitation voltage regulating distribution transformers produced by the company have the characteristics of high efficiency and low loss, which can save a lot of power consumption and operating costs, and have significant social benefits. They are high-tech promoted by the country. product.
1. The transformer body adopts a new insulation structure to improve its short-circuit resistance;
2. The transformer core is made of high-quality cold-rolled silicon steel sheets;
3. The high and low voltage windings of this transformer are made of high-quality oxygen-free copper wire and adopt a multi-layer cylindrical structure;
4. All fasteners of this transformer adopt special anti-loosening treatment;
5. The transformer oil tank has a corrugated structure, and the tank cover and tank edge are either completely welded or fastened with bolts, which fundamentally extends the service life of the transformer oil and insulation materials.
The above standards are subject to the latest published information; equipment requirements should be subject to the corresponding latest national professional standards.
