Medium/ Low Voltage Switchgears

Hyosung Heavy Industries started supplying 25.8kV 25kA medium voltage switchgear in 1984 and has been supplying products and services to various countries for 30 years.(GIS, high-voltage switchgear, low-voltage switchgear, IPB, etc.)

Hyosung Heavy Industries have a wide range of products from 440V to 38kV switchgear.

We have succeeded in developing products that have various safety devices such as internal arc, earthquake proof, IP degree, satisfying various needs of customers such as petrochemical, power generation, electric and electronics

Pro MV SWGR

Hyosung Heavy Industries started supplying 25.8kV 25kA medium voltage switchgear in 1984 and has been supplying products and services to various countries for 30 years. Compact design reduces installation area by more than 40% compared to old switchgear. Pro switchgear is separated all compartments such as breakers, main bus, and both incoming and outgoing connections by earthed(metal partition.), in order to prevent the spread of accident.

Pro GIS

Pro GIS is used in a variety of places such as buildings, factories, trains and other public facilities that require high reliability, stability, and minimum installation area. Hyosung Heavy Industries has a full lineup of models with maximum rated breaking current of 40kA, rated voltage of 24kV to 38kV, and has received international standards such as IEC and IEEE. In addition, we have developed and supplied eco-friendly Dry Air GIS that replaced SF6 gas.
