Vacuum Sintering Transformer Performance
The vacuum sintering transformer excels in power conversion and transmission, particularly under low voltage and high current conditions, delivering exceptional performance.



The use of high magnetic permeability silicon steel sheets and copper wire windings reduces losses, achieving a conversion efficiency of 95%. This improves energy utilization and lowers operating costs.
It precisely regulates current in low voltage, high current circuits, stabilizing the power supply to sensitive electronic equipment, thereby improving operational accuracy.
Vacuum impregnated varnish enhances insulation and dust protection. Combined with an effective heat dissipation design, it controls temperature rise, ensuring stable operation.
