The Siemens range of gas-insulated switchgear (GIS), for rated voltages from 72.5 kV up to 550 kV, is an extremely successful product concept. Since its introduction back in 1968, Siemens has installed switch fields in all climatic zones of the earth, recording

The gas-insulated switchgear from Siemens (DC-GIS) saves space, time money. Based on the proven switchgear-technology it enables in numerous of applications in the high-voltage-direct-current transmission a voltage up to ±500 kV and stands out with an excellence weather resistancy.

2021-2-26The Siemens gas-insulated switchgear (GIS) is an extremely successful product concept. Since its introduction back in 1968, Siemens has installed more than 28,000 indoor and outdoor switchgear bays worldwide, and well over 300,000 bay-years of operation have been recorded. Since 1974 we have supplied gas-insulated substations

2021-2-18Siemens offers support and services far beyond GIS engineering, production, and construction. Complete turnkey solutions, services that cover the entire life cycle of a switchgear system, and dedicated training round out the Siemens high-voltage substation portfolio.

To meet the customers requirements, the latest innovations from Siemens were chosen. This includes the worlds first SF 6-free gas-insulated switchgear (GIS) with a rated voltage of 145 kV.As part of Siemens’ blue portfolio, the GIS is insulated with Clean Air.

2021-3-6Each substation consists of a hermetically capsulated transformer, a gas-insulated medium-voltage switchgear, type 8DJH, and a Sivacon S8 low-voltage switchboard. By using communicating hardware and Internet of Things (IoT) technology, Aral can obtain information about the status of the substations at any time.

2 days agoSiemens Energy Management received an order from Bergenshalvøens Kommunale Kraftselskap (BKK Nett) in Norway to supply the worlds first SF6-free GIS with clean air and vacuum interruption systems for a voltage level of up to 145

Gas-insulated single-pole bus ducts with a total length of 2,700 meters connect the GIS accommodated in the 85-meter-long switchgear building with the air-insulated part of the substation. The 245-kV breakers were the world’s first of its kind to switch a short-circuit current of 80 kA.

Gas insulated substation (GIS) consist of components where active parts on high voltage potential are located in the middle of the aluminium alloy pipes and hold in this location by epoxide resin insulators. The pipes are filled in with insulating gas and have earth potential.
