Product Description

Product Description:

Our products span a wide capacity range from 10MVA to 200MVA, ensuring a versatile solution for various power requirements.

They are specifically designed to address the diverse demands encountered in different applications, including industrial power distribution and the integration of new energy sources into the grid.

This comprehensive range allows us to effectively support scenarios ranging from conventional industrial power supply to modern renewable energy grid connections, adapting to your unique needs.


Features:

The core material consists of cold-rolled silicon steel sheets that possess high magnetic conductivity. To minimize no-load losses, advanced laser cutting and stacking techniques are employed during the manufacturing process.

In the winding process, copper wire is utilized to create the coils. This is complemented by vacuum drying and insulation treatments, which help to maintain the local discharge level at or below 5 picoCoulombs (pC), ensuring optimal electrical performance.

For sealing, a double-layer structure is implemented, combining a rubber gasket with a metal flange. This design undergoes a rigorous 24-hour leakage test to guarantee that no leakage occurs, thereby enhancing the reliability and durability of the assembly.


Applications:

Our design incorporates reinforced insulation to ensure optimal performance and safety in challenging conditions. This enhanced insulation is specifically engineered to withstand extreme environments, including high altitudes where atmospheric pressure and temperature fluctuations are prevalent.

In addition to insulation, we apply a specialized anti-corrosion coating that protects equipment from the damaging effects of high humidity and salt spray. This protective layer significantly reduces the risk of corrosion, thereby maintaining the integrity and functionality of the equipment over extended periods.

By combining reinforced insulation with advanced anti-corrosion treatments, our solutions effectively extend the operational life of equipment. This makes them ideal for use in harsh environments where durability and reliability are critical.
