Transformer Painting Process
The transformer painting process is implemented to ensure long-lasting corrosion resistance, mechanical durability, and aesthetic appearance of transformer vessels and components. The process generally consists of the following steps:
Surface Preparation:
Sandblasting (or shot blasting) is performed to remove rust, oil, and dirt residue from the surfaces of transformer vessels and components. Surface cleanliness and roughness are generally checked according to the Sa 2.5 standard.
Cleaning and Degreasing:
After sandblasting, dust and oil residue remaining on the surface are removed with suitable solvents or compressed air. This process ensures complete paint adhesion.
Primer Application:
After surface preparation, an epoxy-based primer is applied to increase corrosion resistance and enhance paint adhesion. The primer is allowed to dry under controlled temperature and humidity conditions.
Intermediate Coat (Optional):
Depending on customer specifications or protection requirements, an epoxy-based intermediate coat can be applied. This coat enhances surface protection.
Final Coat Application:
An outdoor-resistant polyurethane or epoxy top coat is applied. This coat provides UV resistance, weather protection, and the desired color appearance. The color is usually selected according to customer specifications (e.g., RAL 7035).
Drying and Curing:
Painted parts are dried at room temperature or in an oven, depending on the paint system. This stage ensures complete hardening and durability of the paint.
Final Inspection and Testing:
Paint thickness, adhesion testing, color, and gloss values are checked according to quality standards (e.g., ISO 12944, ASTM D3359). Touch-ups are performed where necessary.
