Product features
High safety
Oil-free design, eliminating oil leakage and fire risk, suitable for applications with high safety requirements, such as hospitals and data centers.
Excellent insulation performance
High-quality insulating material with insulation class F or H ensures good insulation performance even in high-temperature and high humidity environments.
Good Heat Dissipation
Adopting natural air-cooling (AN) or forced air-cooling (AF), it has good heat dissipation capability to ensure that the equipment maintains a stable working temperature under high load conditions, and adapts to the requirements of long-time operation of the energy storage system.
Strong short-circuit resistance
The high-voltage and low-voltage coils are designed with continuous winding and foil structure, and are treated with vacuum pressure impregnation (VPI), which have very high short-circuit and shock resistance, ensuring the reliability of the transformer under various working conditions.
Low loss, energy saving and environmental protection
Adoption of high permeability oriented silicon steel sheet and advanced 45 ° full-slope stepping lap process, reduce no-load loss and no-load current, reduce energy loss in the operation process, in line with environmental protection and energy saving standards.
Low operating noise
Through optimized core design and anti-vibration treatment, the operation noise is lower than 55 dB, which is very suitable for applications in places with strict noise requirements, such as hospitals, smart parks, etc.
