Product Description
Plateau type 12kV vacuum contactor - Single Phase high voltage vacuum contactor, rated voltage 7.2kV, 12kV, rated current 160A~1250A
General Description:
Hai Bang Plateau type 12kV vacuum contactor is dedicated for plateau environment. This type of Single Phase high voltage vacuum contactor is suitable for power systems with AC 50~60Hz, main circuit rated voltage 7.2kV, 12kV, and rated current 160A~1250A. Single Phase Vacuum Contactor is mainly used as a grounding switch when a single-phase ground fault occurs. JCZ1 Plateau type 12kV vacuum contactor is used in arc suppression cabinets and electrical occasions that require single-phase control. The altitude of the environment where the Plateau type single phase vacuum contactor is used does not exceed 5000 meters above sea level.
We also have common types of 12kV(7.2kV) Single phase Vacuum Contactors, which could be used in the environment with an altitude below 1000 meters above sea level. Please refer to the categories for more information.
Types:
JCZ1- TG/D160~1250A-7.2kV
JCZ1- TG/D160~1250A-12kV
Application Condition:
- Ambient Air Temperature: -25℃～+40℃,24-hour average must NOT exceed +35℃;
- Altitude: 5000m or Lower; The patent design makes it possible for the JCZ1 Single phase Vacuum Contactor to operate safely and stably within the altitude of 5000m above sea level.
- Relative Humidity: Daily average less than 95%, Monthly average less than 90%, Must NOT exceed 50% when Ambient Air Temperature reaches +40℃;
- Operation Environment: Ambient air shall not be contaminated by corrosive, flammable or explosive gas and water vapor, Contamination Level: Level III；
- Installation of Plateau type high voltage vacuum contactor:
When operating, the tilt angle between the surface of installed Plateau type Single Phase Vacuum Contactor and the horizontal plane shall NOT exceed 5°.
Note: In case the above conditions cannot meet the user's requirements, the user can negotiate with the manufacturer for special treatment of the product.
