Casted by epoxy resin, 18 ~ 22kV/mm insulation breakdown field, the insulation class is F, the maximum allowable temperature is 155 deg c, the winding temperature rise limit is 100K.
Due to the material properties of the resin, the winding become rigid by heating and curing, so the mechanical strength is high, and the sudden short-circuit test shows that few cast dry-type transformers damaged by short circuit.
Epoxy resin is flame retardant and self extinguishing, and will not cause explosion or other disasters. Superior environmental performance, maintenance free, and strong overload capacity.
