LV winding adopts foil structure, winding with a whole piece of foil, using the resin prepreg poly resin compound cloth for inter turn insulation, sealing the top end with resin. Through high temperature curing treatment, the resins in resin prepreg poly resin compound cloth are released and then are solidified, making the entire coil into a steel entirety. Heatproof grade of the LV winding is F.
LV winding takes the structure of by multi-segment foils winding and winding continuously. By using the poly resin composite film for inter turn insulation, the inner and outer casting layer uses glass fiber grid as support frames, casted by filler resin in a vacuum state. The inner and outer cast thickness is 2~3mm of thin insulation structure. Through High temperature curing, the casting surface is smooth. Heatproof grade of the LV winding is F.
Foil coil has solved the outstanding problems of short-circuit stress, ampere turn imbalance, poor heat dissipation of low-voltage high-current winding products and instable quality of artificial welding.
