Turn-to-turn insulation structure of dry-type iron core reactor

The utility model relates to the technical field of reactors. The utility model relates to a reactor, in particular to a turn-to-turn insulation structure of a dry-type iron core reactor. The transformer comprises a first coil, a turn-to-turn insulation pad and a second coil, the turn-to-turn insulation pad is placed between the first coil and the second coil. The turn-to-turn insulation pad comprises a photosensitive resin layer, an alkoxy tungsten layer, a nanoparticle layer and an ethylene propylene rubber layer. Wherein the alkoxy tungsten layer is fixedly connected to the bottom of the photosensitive resin layer, the nano-particle layer is fixedly connected to the bottom of the alkoxy tungsten layer, the ethylene propylene rubber layer is fixedly connected to the bottom of the nano-particle layer, and the shielding layer is sputtered and deposited at the bottom of the ethylene propylene rubber layer. The turn-to-turn insulation pad is used among turns of a plurality of enameled conductors when the coils
