JB/T 4328.9-1986 "Electrical special equipment, general technical conditions for painting" is a mechanical industry standard, which stipulates the general technical requirements for painting of electrical special equipment. The content includes pre-painting substrate treatment (derusting, degreasing and surface cleaning), Coating performance indicators (adhesion, arc resistance, corrosion resistance, etc.), painting process (primer, topcoat coating method, drying conditions and coating thickness control), Appearance mass requirements (coating flatness, uniform color, no sag, bubble, etc.) and inspection rules. This standard applies to the surface painting of electrical equipment such as transformers and switchgear, aiming to improve the insulation protection, corrosion resistance and aesthetics of the equipment by standardizing the painting process and quality control, meet the reliability requirements of electrical equipment in the electrical environment, and provide technical basis for the painting design, construction and inspection of electrical special equipment.
