The increasing demand for electrical power in cities and industrial centers necessitates the installation of a compact and efficient distribution and transmission network. High voltage gas insulated switchgear (GIS) is ideal for such applications. The TCK2 GIS is a Three phase, SF6 gas-insulated, high voltage metal enclosed switchgear, which is continuously being upgraded to state of the art technology. The TCK2 GIS complements the existing range of GIS products. TOOSCUT has been actively involved in SF6 technology for several decades and since 2016 our GIS has been in use in Iran, with proven success. Excellent field experience confirms the soundness of our technical concept. Indoor and Outdoor GIS are generally selected for many types of power plants and substations to suit in various environment and needs. When it comes to performance and reliability, our GIS products fully comply with the latest international standards with various range of products from 72.5KV to 145KV.
