• Strong overload resistance: Able to withstand short-term power grid shocks or load fluctuations.
• Low-loss and efficient design:
• High-quality and low-loss silicon steel sheets are used.
• Optimize electromagnetic design and manufacturing processes.
• Significantly reduce no-load loss and load loss, save operating costs, and improve the overall efficiency of the system.
