The utility model relates to an insulation anti-corrosion electrical equipment, which comprises an electrical equipment body (1) and an insulation anti-corrosion layer, wherein the insulation anti-corrosion layer is composed of two layers, namely the layer which is close to the surface of the electrical equipment body (1) is an undersaturation medlin solventless impregnated resin layer (2) and the layer which is exposed outside is a fluorosilicone rubber layer (3). The insulation anti-corrosion electrical equipment not only has higher insulativity and but also has the better anti-corrosiveness. The insulation anti-corrosion electrical equipment has good performances of resisting ultra-violet, ozone, oil, chemical reagents, salt fog, temperature change and mold, the specific absorption is 0.16%, the equipment resists the fouling of environment, is non-scale and is not disintegrate. The compound layer of the insulation anti-corrosion electrical equipment has the first level adhesive force, the service life can reach more than twenty years, and the cost is lower. And the compound layer of the insulation anti-corrosion electrical equipment and the electrical equipment body have better consistency.
