gis substation Products for high voltages

Siemens' scope of supply comprises much more than the high-voltage equipment that is required for the operation of a substation. It includes high- and medium-voltage switchgear, transformers, and equipment as well as all ancillary systems for control, protection, communication, and condition monitoring.

    Because of its compactness, the GIS requires less number of lightning arresters compared to a conventional substation. Air can withstand very high voltages for a very short time. However, as the duration of voltage increases, withstand voltage falls off considerably. SF6 exhibits a flat characteristic.
