Abstract
The utility model discloses an insulating self-adhesive film, which is characterized in that the insulating self-adhesive film comprises a polyester thin film layer, a non-woven polyester fabric layer and a semisolid epoxy resin layer, wherein the non-woven polyester fabric layer is adhered through a polyurethane AB adhesives layer and the polyester thin film layer, and the semisolid epoxy resin layer is coated on the surface of the non-woven polyester fabric layer. The insulating self-adhesive film is arranged between dry type transformer main air channels and high-low pressure windings after being formed through self-adhesive, can shield electric fields, reduces the distance of the main air channels, reduces the volume of high pressure windings, saves the use amount of copper materials and resin, thereby reducing the loss of a transformer, saving materials, increasing the economic benefit of the transformer, and having strong practicability.
