Description:

The SAM switchgear from SZM is an SF6-free medium-voltage switchgear and environmentally friendly with reliable vacuum switching technology. The modern air-insulated indoor switchgear is sustainable, efficient, safe and above all compact.

The SAM consists of factory-finished switch panels in metal-enclosed design for a rated voltage of 12 kV that can be connected in series. Fixed switch-disconnectors or circuit-breakers are used as switching devices.

It is mainly designed for secondary mains distribution and thus suitable for use in transformer stations and smaller industrial plants. The system is especially suitable in energy supply containers of common size; due to the small installation depth, the SAM can also be installed in double rows opposite one another, which is something that is possible with only few air-insulated switchgear types.

Manufacturer:

The AIS Medium Voltage Switchgear SAM deserves the title "Made in Germany", being produced at SchaltanlagenZubehör Bad Muskau (SZM). The system is based on a proven switchgear concept from ABB (Calor Emag), Peters & Thieding and IPT - International Power & Technology GmbH (Wentorf near Hamburg).

SZM is a specialist for switchgear, switchgear systems, transformers, substations and in addition to environmentally friendly switchgear systems, ensures a longer operating life for older switchgear systems primarily through retrofit solutions.

Features:

Air-insulated
The SAM uses ambient air as an insulating medium. This eliminates the need to use insulating gases and monitor their pressure. Moreover, air is readily available. What is good for humans and animals is also good for the SAM.  

Environmentally friendly
The SAM naturally does not use the insulating gas sulphur hexafluoride (SF6), which is common in many medium-voltage switchgear. This is considered particularly harmful to the environment: it is 23,500 times more harmful to the climate than carbon dioxide and has a very long residence time in the atmosphere.

Compact
Although SAM is an air-insulated switchgear, it has an extremely compact design. With a cubicle depth of only 800 mm, it is approx. 20 %, i.e. one fifth, shorter than other air-insulated medium-voltage switchgear and is therefore particularly suitable for use in confined spaces (e.g. in containers).

Reliable
The SAM is particularly reliable and easy to maintain thanks to the use of tried and tested components that are particularly durable, such as the shear-load disconnector C3 (manufactured by ABB Calor Emag) and the maintenance-free vacuum circuit-breaker VD4 (manufactured by ABB). Therefore, the SAM is a maintenance-free medium-voltage switchgear for up to 10 years.

Economical
With its minimised space requirement, the SAM also requires less initial investment in the building. It is also particularly reliable and easy to maintain. Its purchase is not only good for the environment, but also for your wallet.

Made in Germany
The SAM is manufactured at SchaltgeräteZubehör Bad Muskau (SZM) and is thus "Made in Germany". Production takes place in modern production halls and quality assurance is carried out in accordance with DIN ISO 9001:2015. SZM is a partner of major electrical companies such as ABB, Siemens and Schneider Electric.
