The High and low voltage switchgear is a device connected to high voltage or low voltage cable. General power supply bureaus and substations use high-voltage cabinets, and thru the power transformer for step down to low-voltage cabinets, then thru low-voltage cabinets to each power distribution box. It is an electric equipment assembled of some switchgear, circuit breakers, protection devices and circuit breakers etc.
The high and low voltage switchgear is an electrical equipment. The outside line firstly enters to the main control switch in the cabinet, and then enters to the sub-control switch. Each branch is set according to its needs. Such as the instrument, automatic control, motor magnetic switch, various AC contactors, high voltage bus, high voltage room and low voltage room switch cabinet, etc.
We are special produced for the different High and Low voltage switchgear. Meanwhile, our company also produce the oil immersed power transformer, dry type transformer, box substation. We are undertake various electric power construction projects.
The high and low voltage switchgear is widely used in the power station, electric power substation, power distribution places for resident community, high-rise buildings, industry zone, metallurgy, rolling mill, chemical, factory, mining and oil field enterprise etc.
