The difference between fully enclosed epoxy potting power transformer and traditional power transformer

May 19, 2021

Fully enclosed epoxy potting transformers, the biggest feature is the relative small size, power density, the degree of protection of the potting is relatively high, and no potting is IP00 level without protection class, the protection class means that dust, waterproof This is the most basic difference. The potted transformers are mainly installed outdoors and can be directly immersed in the bottom of the water. The non-potted transformers can only be installed indoors or in machinery and equipment. Epoxy resin has excellent bonding strength on the surface of metal and non-metal materials, and has good dielectric properties. After curing, epoxy resin has small shrinkage, good dimensional stability, high hardness, and good flexibility. After the transformer is filled with glue, the product has the functions of impact resistance, insulation, fixing and noise elimination; after the transformer is encapsulated after testing, the transformer has good stability and is unlikely to undergo other changes, and the working conditions are not likely to change.

And safety performance in line with national standards (CE), the resistance between the winding resistance can withstand 50Hz3750V rms / 1 minute, internal optional temperature protector, even in the case of transformer load, the case of short circuit, can effectively cut off the power, Preventing equipment from being burned out is the best choice for producing industrial grade equipment.
