GIS technology does the talking

摘要

Convincing experienced switchgear users that GIS gives significant advantages over traditional AIS can be an arduous task for OEMs. But sometimes the technology can Feeder Factory in Ratingen. Availability and reliability are two prerequisites for any equipment manufacturer. For OEMs in the business of power protection and safety this is absolutely essential. Switchgear and its components are a vital link in the transmission and distribution chain. Gas insulated switchgear (GIS) using sulphur hexafluoride (SF{sub}6) has been in use since the 1960s, at high voltage (HV) application first, and medium voltage (MV) much later. Air is also used for insulation but SF{sub}6 has significant property advantages, notably its dielectric and arc quenching strengths. At medium voltage level (generally accepted as between 1-52kV) demand for GIS is increasing, yet OEMs still find that convincing potential customers of its merits over air insulated switchgear (AIS) can be a difficult challenge.
