50-2500kVA/10kV Super Low-loss Dry Type Power Transformer

If you prioritize exceptional energy efficiency, stable power delivery and long-term operational safety for your power distribution system, the SCB13 series 50-2500kVA / 10kV dry-type power transformer stands as the optimal solution for modern industrial, commercial and infrastructure power networks. As a high-performance dry-type transformer fully complying with GB 20052-2020 Level 2, the latest national energy efficiency standard, this product is engineered to satisfy the strict demands of diverse critical applications - including industrial manufacturing, commercial complexes, public infrastructure and other key power sectors. Featuring an oil-free, eco-friendly design, it eliminates the risks of oil leakage, fire and pollution, perfectly addressing the industry's urgent needs for safe, low-loss, maintenance-friendly and environmentally responsible power conversion.

Class-Leading Energy Efficiency for Cost Reduction

The SCB13 series achieves remarkable improvements in energy performance over traditional models. Compared with the mainstream SCB11 series, its no-load loss is reduced by 20%, while the load loss is further optimized by 12%. These substantial reductions in power loss directly translate to lower daily energy consumption, significant cuts in long-term operating electricity costs and a lighter carbon footprint. For end-users, this means not only full compliance with national energy regulations but also tangible economic benefits throughout the transformer's service life.

Outstanding Structural Stability & Mechanical Strength

Built with a sophisticated multi-layer dense winding structure and processed via high-temperature and high-pressure curing technology, the transformer delivers exceptional mechanical robustness. The production process strictly controls the thickness tolerance of the insulation layer within ≤ 0.1mm, ensuring uniform insulation distribution, enhanced resistance to short-circuit currents, voltage shocks and long-term cyclic loads. This premium structural design greatly reduces the probability of failure and ensures uninterrupted power supply even in harsh operating environments.

Ultra-Low Partial Discharge for High Operational Safety

The product maintains an ultra-low partial discharge level of below 5pC, far exceeding industry average standards. This critical performance indicator effectively suppresses insulation aging and electrical corrosion, minimizing the risk of insulation breakdown and internal faults. Combined with its fire-retardant, non-polluting dry-type structure, it provides a high-safety power solution for densely populated areas, indoor power stations, commercial centers and other safety-sensitive scenarios.
