Plateau Type 3 Phase Vacuum Contactor High Voltage 1250A

Hai Bang Plateau type High Voltage Vacuum Contactor is dedicated for plateau environment. It is suitable for power systems with AC 50~60Hz, main circuit rated voltage 7.2kV, 12kV, and rated current 160A~1250A.JCZ9 Plateau Type 3 Phase vacuum contactor is used to directly or remotely connect and disconnect the main circuit, control AC motors, transformers and other electrical equipment. The altitude of the environment where the Plateau Type 3 Phase vacuum contactor is used does not exceed 5000 meters above sea level.

Types:

JCZ9-7.2-JTG/D160~1250

JCZ9-12-JTG/D160~1250

Application Condition:

1. Ambient Air Temperature: -25℃～+40℃,24-hour average must NOT exceed +35℃;
2. Altitude: 5000m or Lower; We have applied the patent, which shows the JCZ9 plateau type vacuum contactor can operate safely and stably within the altitude of 5000m above sea level.
3. Relative Humidity: Daily average less than 95%, Monthly average less than 90%, Must NOT exceed 50% when Ambient Air Temperature reaches +40℃;
4. Operation Environment: Ambient air shall not be contaminated by corrosive, flammable or explosive gas and water vapor, Contamination Level: Level III；
5. Installation of Plateau Type vacuum contactor:
When operating, the tilt angle between the surface of installed Plateau Type high voltage 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.

Technical Data:

Remark:
1. Rated control voltage can be made according to customer’s requirements.
2. For the mechanical holding type, the locking device needs to be replaced every 100,000 times.
3. The product can be used for 1250A or 15KV (common type) by special manufacturing.
