well known symbol of the German design
and technology in the sector.
Based on our customers' demands, the
modular version of ga (then called GE)
was designed and developed in 1993 to
provide flexible solutions to the electrical
networks and transformer distribution
substations. In 2001 this modular system
was upgraded to a fully gas-insulated
extensible switchgear system and begun
to be known as gae.
Since then both ga and gae630 systems
have been continuously evolving every
year into a more extended and more
ecological range with higher ratings to
respond to the changes in the design
parameters of the electrical network.
Also both systems have already been
integrated into several smart-grid
applications. Today more than 700.000 ga
and gae630 system functional units have
been installed in more than 80 countries.
The ga and gae630 system provides you
with reliable and efficient distribution
network solutions (DNS) for all kinds of
MV installations from electrical utilities to
infrastructures, from leisure facilities to
industrial installations, and from
wind farms to PV plants.
