This series of transformers is designed to directly step down 20kV and 35kV grid power to 400V distribution power or 10kV transmission power for end users. Due to its significant advantages, it has been widely adopted in an increasing number of engineering projects.
1. Reduced land occupation and fewer multi-stage substation projects, providing significant social benefits.
2. Lower project investment and improved economic efficiency.
3. Reduced 10kV transmission and distribution stages, significantly lowering operation and maintenance costs.
4. High-voltage, low-current transmission replaces low-voltage, high-current transmission, reducing line losses and operating costs.
5. 35kV and 20kV power can directly enter the load center, effectively improving power supply reliability.
The SCB10 series 20kV and 35kV non-excitation tap-changing dry-type transformers produced by our company are low-loss products that comply with international standards and feature the following advantages:
1. High performance and low loss, serving as an upgraded replacement for the previous Class 9 series products.
2. High-quality silicon steel sheets are used while significantly reducing magnetic flux density, minimizing magnetostriction during operation and effectively lowering noise levels.
3. The optimized high-voltage winding structure improves interlayer voltage and capacitance distribution, greatly enhancing the transformer’s resistance to lightning overvoltage and switching overvoltage impacts. It also improves electric field distribution and further reduces partial discharge levels.
4. Optional temperature control systems and forced air cooling devices can be configured. When the load becomes excessive, the cooling fan system starts automatically, effectively improving overload capacity.
