Dry Type Transformer
Utilizing the German HEDRICH epoxy resin vacuum casting process, these transformers achieve H-class insulation, a partial discharge rating of ≤5pC (far exceeding the industry standard of 10pC), and a noise level as low as 42dB (equivalent to an office environment). Their oil-free design has passed EU fire certification (EN 13501), making them suitable for use in energy storage systems, urban substations, commercial complexes, data centers, hospitals, and other locations with stringent safety and environmental requirements. They can be installed directly close to load centers, reducing power losses by over 8%. We also manufacture phase-shifting transformers to meet the power needs of AIDC and other high-power variable-frequency loads.
Our Product Advantages
Outstanding Short-circuit Withstand Capability
Copper foil windings combined with a reinforced core clamping structure provide short-circuit strength 20 percent above European requirements. The transformer endures extreme electromechanical forces without winding deformation or damage, ensuring grid safety and stable operation.
Flame-retardant and High-temperature Resistant for Wide Applications
Using Class H insulation materials, the system achieves a maximum temperature withstand of 180 °C and operates reliably in ambient conditions from −40 °C to +85 °C. It shows no thermal aging at elevated temperatures and is suitable for demanding environments such as high-temperature regions or high-altitude installations.
Low Noise and Energy-efficient for Precision Environments
Noise-optimized winding design and vibration-damping construction reduce operational noise by 5 to 8 dB compared to typical products. The low no-load current further boosts energy efficiency. This makes the transformer ideal for hospitals, data centers, and other locations with strict noise and power quality requirements.
