1. High efficiency, energy saving, and stable operation

Made of highly magnetic permeability silicon steel, it offers low temperature rise, low loss, and transformer operating efficiency of over 95%, reducing reactive power loss and improving energy utilization; At the same time, it has strong overload capacity and can handle short-term load fluctuations.

2. Multiple excellent performance

Made with high-quality copper wires, minimal partial discharge, high electrical strength; At the same time, it has strong overload capacity and can withstand the impact force of sudden short circuits, with good thermal and dynamic stability; Good heat dissipation, low temperature rise, low loss, high power factor, and high operational efficiency.

3. Excellent craftsmanship

Manufactured using advanced processes such as VPI (Vacuum Pressure Impregence) and Wrap Winding, which offers superior insulation performance and reduces noise and vibration during operation; At the same time, it uses coil wrapping technology to improve spatial efficiency and power conversion efficiency.

4. High safety performance

Uses a dry insulation structure, eliminating oil leakage and fire hazards. At the same time, safety, flame retardancy, and fire resistance performance meet domestic and international technical standards, greatly improving safety and making it suitable for locations with high fire and explosion prevention requirements.
