Prepreg DMD for dry transformer

Pre-impregnated Material DMD(Class F)formed in the process of precuring the modified F-class DMD with impregnation of Hi-temp resistant Epoxy resin into B-stage by baking.

Prepreg DMD is made by the process of pre-curing the modified F-class DMD with Impregnation of Hi-temp resistant B-stage Epoxy resin by baking, with long shelf life at room temp, low pre-curing temp & time, excellent electrical insulation, bonding and heat-resistant properties.

Electrical insulation materials are key part of transformers, as they must withstand the thermal, electrical, mechanical, and environmental stresses during the transformer's operating life. Hence the lifetime of a transformer is largely depends on the reliaility of the insulation used. Ventilated dry type transformers (VDT) and cast resin transformers continue to grow in popularity around the world.
