    Product details advantage


    1. The windings are made of class H enameled copper/aluminum wire, which can withstand temperature up to 180 ° C, is well insulated and durable.

    2. New high-quality cold-rolled silicon steel core, good heat dissipation, low core loss;

    3. The transformer whole H class insulation varnish vacuum impregnation, has the extremely high heat resistance, and anti-corrosion, the running noise is low, the insulation performance is good.


    This series of single-phase transformer is widely used in CNC machine tools and mechanical equipment, elevator control cabinet, working lighting and signal lamp power supply, can also be used as a small power supply.
