Description
The vacuum drying oven is designed for drying the parts and elements of transformers, reactor and related electrical products. The transformer drying equipment adopts variable pressure drying principle suggested by Dr. Moll from Germany. It can save about 30-45% time of drying compared with conventional vacuum drying system. Rectangle and round chamber can be option according to the production need.
Applications
1. 10-110KV/100MVA level transformer body drying
2. 110-500KV level transformer winding drying
3. 110-1000KV level current/voltage reactor body drying
4. Capacitor drying
5. Other electrical material drying
Characteristics
1. With advanced heating principle, the vacuum drying oven enjoys high production efficiency.
2. Variable pressure with heating temperature ensures smooth drying condition.
3. Modular design, PLC automatic control with touch screen operation
4. Convenient operating with complete parameter indicating, recording and alarm.
