Functional Advantages
Flexible Dual Voltage Conversion: This transformer can flexibly switch between 20KV and 10KV high voltage inputs, adapting to different power supply conditions. It ensures a stable low voltage output of 400V regardless of variations in the power grid voltage, meeting the needs of various electrical equipment.
Design Features
- Core Manufacturing:
Uses high-quality cold-rolled silicon steel sheets with advanced cutting and stacking processes to ensure magnetic performance and mechanical strength. Precise annealing is applied to reduce core losses and noise.
- Winding Manufacturing:
Utilizes high-conductivity copper or aluminum conductors with advanced winding techniques to ensure electrical performance and mechanical strength. Winding is subjected to rigorous insulation treatment with multi-layer insulation paper and varnish to enhance insulation performance and thermal rating.
- Quality Testing:
Each transformer undergoes strict quality testing, including electrical performance tests, insulation resistance tests, high-voltage tests, and temperature rise tests. Only products that pass all tests are allowed to leave the factory, ensuring that users receive high-quality and reliable transformers.
project case
- In September 2023, our long-standing customer from Azerbaijan, Gol, introduced Jimmy to us. Jimmy is the owner of a construction company.
- Gol informed us that Jimmy's company was in urgent need of 20kv/10kv dual-voltage conversion S11 series oil-immersed distribution transformators. Soon after, Jimmy visited our factory to inspect our production capabilities and product quality. We warmly received him and gave him a detailed tour of our manufacturing facilities.
- During the visit, our technical team explained the features and advantages of our transformators in detail, emphasizing their high performance and reliability. Jimmy was impressed by our advanced technology and strict quality control measures.
- After thorough discussions and negotiations, Jimmy decided to place an initial order with us. The value of this order reached 590,000 US dollars, including a significant quantity of transformator 10kv 400v models.
- We are grateful for the trust and support from both Gol and Jimmy. This successful cooperation not only strengthened our business relationships but also laid a solid foundation for future collaborations.
