ZJ-1200
4000m3/h Premium Ultra-High Vacuum Pumping System
- The ZJ series Premium Ultra-High Vacuum Pumping System is mainly used for vacuum drying and vacuum oil-injecting for high voltage electrical transformers.
- The transformers can be 220KV, 500KV, ±800KV, or 1000KV.
- Strong vacuum pumps make the working vacuum degree to 10 Pa and the limit vacuum degree to 1 Pa.
The ZJ-1200 is a top-tier ultra-high vacuum pumping system for the highest 1100 kV UHV transformer core and body manufacturing. Three-stage pumping structure delivers an extremely high vacuum level for critical processes.
It provides top-level performance and supports long-term heavy-duty industrial operation. It integrates a professional GIS vacuum port to meet high-precision requirements of critical UHV GIS components.
