Product advantages
Transformer core products have superior performance in various aspects, including low loss, low noise, low no-load current, high mechanical strength, strong short-circuit resistance, small partial discharge, good insulation performance, good thermal stability, precise size,small burrs, excellent process coefficient,beautiful appearance and so on.We provide a full range of iron core solutions for voltage levels from 10kV to 1100kV.
JULONG is an exclusive customer of Baosteel, and the quality of silicon steel sheets is fully guaranteed.
Silicon steel sheets are processed using GEORG fully automatic intelligent production line, with high processing accuracy, small burrs, good flatness, high efficiency, and greatly shortened delivery cycle.
The intelligent workshop is constant temperature, humidity, and dust-free. The entire process from raw materials to finished iron cores reduces additional stress on silicon steel, reduces the manufacturing process coefficient of iron cores, and effectively ensures product performance and quality.
The use of JULONG's unique full sequence stacking method, advanced technology and equipment has significant effects on product energy conservation, environmental protection, and other aspects.
The clamp is made of high-strength steel, which is formed by CNC bending. Compared to channel steel, it has higher mechanical strength, more precise dimensions and positioning, and a smooth and beautiful appearance.
The iron core insulation uses PET (Class F) insulation material to ensure that the transformer will not experience discharge, leakage, breakdown, and other phenomena.
