Product Description
The body of this product adopts a new type of insulation structure to improve its short-circuit resistance.
The iron core is made of high-quality cold-rolled silicon steel sheet. The high-voltage windings are made
of oxygen-free copper wire and adopt a multilayer cylindrical structure. The firmware uses special
anti-loosening treatment. The product has the characteristics of high efficiency and low loss, which can
save a lot of power consumption and operating costs.
