Progress of Our Gas Insulated Switchgear

摘要

In this paper, it is described how the progress of development of Gas Insulated Switchgear has been made. Production of Gas Insulated Switchgear (GIS) has been commercialized in late 1960's. In, comparison with conventional type substation like Air insulated substation, GIS substation has made it possible to achieve the considerable space reduction. Since its introduction, Nissin has installed more than 10,000 bays worldwide. We pioneered the compact design and technology of GIS and continue to be a leading supplier for rated voltage of 72kV & 84kV in domestic market Since 72kV & 84kV GIS was mainly developed in the initial stage, we have extended our product range from 7.2kV to 252kV. Global market has continued to grow and we have already established manufacturing companies both in Taiwan & China late 1990's and early 2000's to focus on regional market demand We have been increasing the number of GIS installation in global market With respect to ever-increasing and diverse customer's requirements such as maintenance-free, environmental harmony, we are committed to developing, innovating and improving technology for further new application of GIS as the key equipment of substation system.
