Open ventilated amorphous alloy 3D wound core dry type transformer, closed type 3D wound core structure, give full play to the low loss characteristics of amorphous alloy, and overcome processing technical difficulties such as hard, thin and brittle amorphous alloy strips. It adopts a insulation system composed of NOMEX® aramid insulating paper, PIF polyimide film and German Elantas single-component environmentally friendly insulating paint, making our product has the obvious advantages of low loss, strong short-circuit withstanding ability, low noise, fire and explosion-proof, moisture and dirt resistance, strong weather resistance, no crack, small partial discharge, etc. Our products have solved the problems of noise, stability and short-circuit resistance of traditional amorphous alloy transformers, and the technology has reached the international leading level.
