Which drying in industry solutions are used for transformer insulation?

Vacuum drying is the industry standard for drying transformer insulation before oil filling. This ensures that moisture absorbed by paper or cellulose insulation is completely removed. Fluidex offers vacuum drying units specifically designed for transformer tanks. These units are commonly used after repairs or during manufacturing of new transformers. Skipping this step can drastically reduce insulation lifespan, so it’s a must-have for any serious transformer maintenance process.
