Dry Type and Oil Type Transformer Iron Cores

1. We provide customers with high-quality stacked transformer cores with capacities ranging from 10KVA to 50000KVA. The supply is made according to the customer's drawing parameter requirements.

2. The Transformer iron core adopts a new fully inclined, seven-step stepped stacked joint form, which can reduce the magnetic density at the joint by about 22%, reduce no-load loss by about 3%, reduce transformer noise by 2-3 decibels, and reduce no-load current by about 40% compared to the conventional push joint type iron core. Stacking 7 pieces at a time greatly improves the stacking efficiency. Large transformers adopt a fully inclined, longitudinal broken yoke, seven-step stepped stacked joint form, which not only has the above advantages, but also facilitates customer disassembly and insertion work.

3. Our company produces Transformer iron cores with superior performance, such as low loss, low noise, low no-load current, high mechanical strength, short-circuit resistance, small partial discharge, good insulation, good thermal stability, precise size, small burr, excellent process coefficient and beautiful appearance. These advantages are achieved and guaranteed by.

4. We maintain a long-term and stable direct supply relationship for Bao Wu silicon steel sheets, which fully guarantees the quality of silicon steel sheets for core main materials.

5. Silicon steel sheet is processed by international advanced automatic intelligent production line with high precision, small burr, good flatness, high efficiency and shortened delivery cycle.

6. The whole process from raw material to finished iron core reduces the additional stress of silicon steel and reduces the coefficient of core manufacturing process, which effectively guarantees the product performance and quality.

7. The insulation is made of PET (Class F) insulating material. Compared with common insulating parts, the insulation grade of PET is higher (insulation resistance can reach at least 1000 MW), the processing technology is simple and the thermal stability is good, which ensures that the transformer will not produce discharging, leakage, breakdown and other phenomena.
