Oil-immersed Transformer
Utilizing European-standard insulating oil and a high-silicon steel core, they offer heat dissipation efficiency 15% higher than the industry average and short-circuit resistance 1.8 times that of IEC standards. All products are guaranteed to be TÜV certified upon delivery. They can be widely used in large-scale power stations, transmission and distribution networks, industrial parks, and construction industries, and can operate stably in extreme environments ranging from -30°C to 50°C.
Our Product Advantages
Ultra-low losses and top-tier energy efficiency
The use of high-permeability grain-oriented silicon steel and an optimized winding design keeps both no-load and load losses more than 15 percent below European limit values. This significantly reduces long-term energy consumption and achieves top-level efficiency performance.
High Cooling Performance and Strong Overload Capability
An intelligent thermal management system combined with high-thermal-conductivity insulating oil increases cooling efficiency by 20 percent under normal operating conditions. The transformer can safely handle short-term overloads up to 1.5 times its rated capacity, making it well suited for applications with fluctuating load profiles and ensuring consistently stable output.
Reliable Insulation and Extended Service Life
High-quality insulating oil tested to IEC and ASTM standards, together with a precise vacuum-drying process, delivers insulation strength well above industry averages. The system withstands moisture and temperature variations effectively. Core components reach a service life of more than 25 years, reducing replacement and overall lifecycle costs.
