The Plant is designed for vacuum degassing, preliminary drying and drying the solid insulation of power transformers up to 1150 kV, tanks of which withstand residual pressure 26 Pa (0.2 mm of mercury column) during installation and repair of them.
Using the Plant for transformers tanks which don't withstand residual pressure 26 Pа is possible after tank strengthening.
