Product profile: It is mainly used for the production of epoxy resin cast dry-type transformers, transformers, reactors, and high-voltage switch insulators below 35kV, and can also be used for the vacuum casting molding of power and electronic components that require epoxy resin encapsulation. Working principle: Using different working units, under the condition of being isolated from the air, process the casting materials to make them dehydration and deaeration, and heat them to a certain temperature, and then mix them uniformly according to the required proportion, and cast the processed materials into the coil mold in a full vacuum state.
