Gas insulated switchgear (GIS) is installed as substation equipment and receiving equipment for safe and stable supply of electricity. Circuit breakers, disconnectors, earthing devices, etc. are enclosed and stored in metal containers using a high-insulation-performance gas. Thus, the equipment is very compact, reliable, and safe.
Since the start of development in 1968, we have endeavored to improve performance and pursued compactness, reliability, and economy. We offer a lineup from 24 kV to 145 kV.
We have delivered products to ASEAN countries, such as Singapore, Thailand, the Philippines, and Vietnam, as well as the Middle East and Africa.
