Description

General Description:

Hai Bang High Voltage Horizontal Vacuum Contactor is applicable on AC 50-60Hz power systems, rated voltage 7.2kV and 12kV, rated current 160A, 250A, 400A, 630A. This type of high voltage vacuum contactor is used to directly or remotely connect and disconnect the main circuit and frequently control capacitive loads, AC motors, transformers and other electrical equipment. This type of Horizontal Vacuum Contactor is used in power grid reactive power compensation, chemical industry, metallurgy, water supply and drainage treatment, coal mine equipment and other occasions. The altitude of the environment where the Vacuum Contactor Unit is used does not exceed 1000 meters above sea level.

Application Condition:

a. Ambient Air Temperature: -25℃～+40℃,24-hour average must NOT exceed +35℃;

b. Altitude: 1000m or Lower;

c. Relative Humidity: Daily average less than 95%, Monthly average less than 90%, Must NOT exceed 50% when Ambient Air Temperature reaches +40℃;

d. Operation Environment: Ambient air shall not be contaminated by corrosive, flammable or explosive gas and water vapor, Contamination Level: Level III;

e. Installation of 7.2kV Horizontal Vacuum Contactor:

When operating, the tilt angle between the surface of installed Vacuum Contactor unit 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.
