Oil-immersed transformers are critical equipment in power distribution systems, often exposed to harsh environments for extended periods. Paint coating plays a vital role in their protection. Transformer tanks, typically made of welded steel plates and filled with petroleum-based transformer oil, require specialized protective coatings to prevent internal corrosion.

Recommended Coating：Jinuo Shengcheng JNHD-8112 Epoxy Paint

Features of JNHD-8112 Epoxy Paint

1. High Barrier Properties:Exhibits excellent oil resistance and acts as an effective barrier against oil penetration.

2. Strong Adhesion:Particularly suitable for sandblasted steel surfaces, providing superior coating adhesion.

3. Excellent Anti-Corrosion Performance:Ideal for protecting mechanical equipment, coastal areas, and underwater environments from corrosion.

4. Good Heat Resistance:The paint film can withstand temperatures up to 200°C, ensuring reliable protection even at the transformer's operating temperature of around 100°C.

Construction Steps

1. Surface Preparation:The interior of the tank must undergo sandblasting to remove rust, dust, and oil stains. The surface should be roughened to enhance the adhesion of the paint film.

2. Coating Application:Apply the paint using spraying or brushing methods. A recommended film thickness of at least 150 micrometers is advised for optimal protection.

3. Drying Time:After coating, allow the paint to cure for at least 7 days to ensure complete drying.During this period, avoid impacts and exposure to water, oil, or other substances.

By following the correct coating process and using high-performance JNHD-8112 Epoxy Paint, the interior walls of the transformer tank can be effectively protected, significantly extending its service life.
