1. Structural breakthrough: The three-dimensional winding iron core adopts three-dimensional winding technology, breaking the limitations of traditional planar laminated iron cores, achieving complete symmetry of the three-phase magnetic circuit, and significantly reducing no-load losses and noise.
2. Advantages of closed core technology: The fully enclosed iron core structure reduces joint air gaps, reduces magnetic leakage and eddy current losses, and improves energy efficiency (usually meeting the national energy efficiency level one standard).
3. Material innovation: Adopting high magnetic conductivity cold-rolled silicon steel sheets combined with annealing process to optimize magnetic circuit distribution, the material utilization rate is increased by about 10% to 15% compared to traditional transformers.
5. Compact design: The three-dimensional coil iron core has a small volume and light weight, saving installation space and suitable for compact scenarios such as urban distribution rooms and new energy power stations.
6. Heat dissipation optimization: Combined with a closed structure and oil immersed cooling system, the temperature rise distribution is uniform, extending the insulation aging cycle, and the design life can reach more than 30 years.
7. Environmental compatibility: Environmentally friendly insulation oil (such as ester oil) can be selected to reduce the risk of fire and environmental pollution, in line with the development trend of green power grid.
8. Strict testing standards: Through multiple certifications such as national standard, IEC, IEEE, etc., covering tests such as sudden short circuit, lightning overvoltage, temperature rise limit, etc., the reliability is significantly higher than that of conventional products.
9. Whole life cycle management: From raw material screening to process control (such as vacuum impregnation and sealing welding), achieving full traceability and reducing the failure rate by about 40% compared to traditional products.
10. Enhanced adaptability: Designed for harsh environments such as high humidity, high altitude, and pollution, with a protection level of IP67, suitable for diverse application scenarios.
