Vacuum Drying Plant

For Power Transformers, Distribution Transformers, Capacitor, CT & VT, Bushing, Coil Drying.

Vacuum Drying Plant is designed for drying the transformer coils, core-coil assembly by applying heating and vacuum.

The vacuum oven can be designed in cylindrical or rectangular shape. The oven door can be opened and closed either sliding door horizontally by electric motor or chain or hydraulically from top side. The door can be clamped either manual clamps or by hydraulic clamping arrangement.

Intensive heating of the complete oven is ensured by tubular elements welded to inside, which are heated either by hot water, saturated steam or heat transferring oil or direct electric heaters fitted Inside the vessel.

The complete process is controlled either by manually or fully automatically by means of the electric control panel provided with a freely programmable logic control or DCS.

The quantity of condensate water collected at vacuum pumping system is recorded at regular intervals. Insulation resistance, power factor and dispersion factor of windings are also monitored.
