Whether power supply, industrial or power station applications - every operator of medium-voltage switchgear has different, process-specific requirements.

The main task of medium-voltage switchgear is cost-efficient and safe power distribution. This is a responsibility we accept, and that is why we offer services and solutions for all requirements of medium-voltage systems to our customers worldwide.

With air-insulated switchgear from Siemens you are always on the safe side - our switchgear is type-tested for indoor installation according to IEC 62271-200. In this way you profit from our leading position as regards fulfillment of this new standard IEC 62271-200. Regardless of the fact that air-insulated switchgear from Siemens has always been a synonym for maximum personal and operational safety as well as local added value.
Besides the corresponding voltage levels, there are other additional aspects like environmental independence, maintenance-free design, compactness, security of investment, cost-efficiency, service friendliness and flexibility - always according to the specific demand.

This offers the high benefit of maximum supply reliability in the network.
The SIEMENS type-tested switchgear range (about 600,000 feeders in operation world-wide today) covers every special requirement.

The product range covers:
Air Insulated Switchgear (AIS) for primary distribution
Air Insulated Switchgear (AIS) for Secondary Distribution Systems
Gas Insulated Switchgear (AIS) for primary distribution
Gas insulated Switchgear (AIS) for Secondary Distribution Systems.

Range of Application:

• Switchgear for the primary distribution level

For the distribution of electrical energy, Siemens offers various switchgear types, which can be used in transformer and distribution systems of power supply companies, but also in industrial medium-voltage systems, e.g.  mining industry, steel works or paper industry. Siemens gas-insulated switchgear is also the first choice for special applications such as wind parks, offshore platforms and ships

• Switchgear for the secondary distribution level

For the distribution of electrical energy, Siemens offers various switchgear types. In compact substations or small distribution substations, such switchgear contributes to guaranteeing uninterrupted power supply through to households, small industries and public utilities, such as high-rise buildings, railway stations, hospitals.
