NOVELTY - The utility model claims a waterproof epoxy resin casting dry-type transformer, comprising a transformer main body, the transformer main body top end and the transformer main body bottom end respectively provided with an upper clamping plate and a lower clamping plate, between the upper clamping plate and the lower clamping plate is respectively provided with an iron core frame, the iron core frame fixedly connected with with multiple iron core bodies by graphene coating; the iron core body comprises an inner core body, a low-voltage winding and a high voltage winding, the high voltage winding is provided with a transformer leading-out wire. Beneficial effects: secondary graphene coating so as to quickly absorb the heat on the iron core frame, so as to transmit to the splint; the splint is made of radiating copper plate, making it reach good heat conducting effect, and the inner side of the clamping plate is provided with a radiating plate, the radiating plate is further matched with the copper tube and radiating fins to further improve the radiating heating area, and the heat can be dissipated quickly; finally improving the radiating capability of the transformer.
