Metal Housing for Gas-Insulated Switchgear (GIS)
Gas-insulated switchgear (GIS) is a compact metal encapsulated switchgear consisting of components such as circuit-breakers and disconnectors, which can be safely operated in confined spaces. GIS is used where space is limited, for example, extensions, in city buildings, on roofs, on offshore platforms, industrial plants and hydropower plants. We have contracted to make a variety of housing subjected to machining(milling, drilling, etc.) for GIS and other power transmission systems.
Material Introduction
We provide a comprehensive range of cost effective metal casting parts like GIS housing, wind turbine hub, machine bed with large size to customers around the globe. We can work with all the typical metal materials, such as carbon steel, stainless steel, aluminum alloy, etc.
