Gas insulated switchgear
High-quality GIS – gas insulated switchgear: GI-2
We engineer reliable switchgear built on safety and care for the environment
It’s our newest SF6 insulated Switchgear: the “GI-2”. It’s a metal-clad and first-rate GIS switchgear solution for single-busbar applications and indoor installation.
Modular design
Metal Clad
Rated voltage 36kV
The GI-2 system is a modular concept based on the “building blocks” principle. This means that cubicles are produced in series. Consequently, in a rational, economically sustainable way, the modular GI-2 design meets the highest technical requirements. The combination in cubicles is unlimited. Through this broad range of possibilities, very complex distribution and transformer switchgear diagrams can be compiled. Our GI-2 GIS solution can always be expanded, compartmentalized and can support up to 24 kv.
A wide range of applications are provided by the GI-2 cubicles and can be used in many industries worldwide. Distribution and dispersion switchgear, electrical substations and medium voltage engines, wind generators, cogeneration, and much more can be used with GI-2 cubicles.
For all your needs and specifications, the GI-2-concept offers a solution: it suitable to use with transformer and switching substations. Therefore, it is important to know that the GI-2 is a compact solution for heavy industry and power stations. Moreover, it is designed to extend the lifespan of your switchboard and ensure the operator’s safety. The GI-2 is very much a cost effective investment because of the benefits of reduced operating costs and maximum supply reliability.
