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.
