Description:
This kind of furnace adopts variable-pressure drying principle suggested by Dr. Moll from Germany, specialized for drying transformer and power capacitor bodies. Comparing to conventional vacuum heating drying method, drying duration of this variable-pressure type has been saved about 30-45%.

Applicationt:
- Drying transformer bodies in grade 10~110kV, capacity less than 100,000kVA
- Drying transformer windings in 110~500kV grade
- Drying current transformer and potential transformer bodies in 110~500kV grade
- Drying power capacitors
- Drying other electrical materials

Main features:
- Compact structure, small occupation
- High productivity: when drying one 110kV, 40000KVA transformer body, it will take only about 50 hours, close to that by kerosene vapor-phase drying equipment
- Heating system is controlled by power control module, assuring even and stable temperature; Real power consumption during temperature-keeping is only about 35% of total power; There is no fluctuation of heating load and thus reduces actual heating power very much.
- PLC control, high automation, more stable and reliable
- Special baffle valves for vacuum drying, better vacuuming performance
