Multi-layer winding coil Low-voltage coil adopted high quality foil and rolled with the automatic foil machine, argon arc welding with high-accuracy standard; presoak dmd in the interlamination as insulation material. Use presoak glass for insulation both outside and inside, sealed with epoxy resin, followed by solidify in the curing oven, in order to reached the target of high level of humidity resistance. About amorphous metal transformer Amorphous metal transformer introduction The development of the amorphous metal in 1970s, it has been widely used in 1990 for a high energy saving material for the transformer industry. Right now, over one million sets of amorphous metal type transformer had been connected to grid all over the world. The longest proven save and reliable transformer had been running for more than 30 years, and it still perform satisfactory in the power industry. The energy saving is huge and it shall be the new era products in the power industry
