Insulator support and transformer

The utility model discloses an insulator support which comprises a transformer provided with radiating fins and an insulator and further comprises a U-shaped support fixedly installed between the transformer and the insulator, a connecting support is fixedly installed on the U-shaped support, and a plurality of radiating plates abutting against the radiating fins are fixedly installed on the connecting support. According to the insulator bracket provided by the utility model, a certain distance is kept between the insulator and the transformer through the U-shaped bracket, so that external air can conveniently ventilate and dissipate heat between the insulator and the transformer; and meanwhile, heat absorbed by the U-shaped bracket is transferred to the connecting bracket, and the heat on the connecting bracket is transferred to the radiating fins under the action of the radiating plate, so that external air cools the radiating fins and the radiating plate while cooling the radiating fins, and the heat gener
