Product Description :
Specially purpose Power Transformer main application site is the factory, used for dust prevention, heat resistance, moisture resistance and other places with special requirements. The requirements for core materials are higher than other ordinary power transformers, so they require higher precision in the processing process. The choice of materials is more stringent
Characteristics of CRGO electrical steel are affected by impurities, grain size, grain orientation and surface insulation. Even minor stresses, burrs, edge cambers or bends can increase core losses and magnetizing current significantly.
Product advantages
Specially purpose Power Transformer core products have superior performance, with the advantages of low loss, low noise, low altitude load current, high mechanical strength, strong short circuit resistance, small local discharge, good insulation performance, good thermal stability, accurate size, small burr, excellent process coefficient, beautiful appearance and so on.
1. Adopt major domestic steel mills in China and around the world, and maintain a long-term and stable direct supply relationship of silicon steel wafers, so as to fully ensure the best quality of silicon steel chips, the main material of the iron core.
2. Silicon steel sheet adopts the international advanced automatic intelligent production line processing, with high processing precision, small burr, good flatness, high efficiency, and greatly shorten the delivery cycle.
3. No driving in the whole manufacturing process, and the intelligent workshop has constant temperature, humidity and dust-free. The whole process from raw materials to the finished iron core reduces the extra stress of silicon steel, reduces the manufacturing process coefficient of the iron core, and effectively ensures the product performance and quality.
4. Adopt unique full-sequence lamination method, advanced process and equipment, which has a remarkable effect on energy saving and environmental protection of products
5. The clam parts are made of high strength steel, formed by numerical control bending. Compared with the groove steel, they have mechanical strength, more accurate size and positioning, and smooth and beautiful appearance.
