What are the advantages of transformer sealing?

Epoxy resin has excellent adhesive strength and good dielectric property to the surface of metal and non-metal materials; the cured epoxy resin has small shrinkage, good dimensional stability, high hardness and good flexibility. After the annular transformer is filled with glue, the product has the functions of shock resistance, insulation, fixation and noise elimination; after the transformer is filled and sealed after test, the stability of the transformer is good, other changes are not easy to occur, and the working condition is not easy to change
