Introduction
SafeRing and SafePlus switchgear for secondary distribution were developed
by ABB in Skien and introduced to the markets in 2000, replacing the previous
SF6 insulated products RGC and CTC. The installed base of SafeRing/SafePlus
is more than 150 000 switchgears in more than 100 countries all over the world.
The switchgear portfolio is constantly under development
to adjust to new market requirements and customers’
needs. SafeRing is available in standard configurations
based on a high-volume production. These standardized
RMUs, which are the most required configurations within
a distribution network, can be extendable upon request.
SafePlus is the switchgear version of SafeRing with
flexibility, modularity and higher ratings.
