Introduction
General aspects
UniSec is an air-insulated switchgear for indoor use,
designed for the secondary distribution of medium
voltage. UniSec switchgear is the result of on-going
innovation and the desire to meet the requirements
of a constantly evolving market.
This new series of switchgears offers a broad range
of technical solutions built to last over time.
Safety, reliability, ease of use, simple installation
and environmental sustainability are the key
features that guided the development of this
switchgear.
UniSec assemblies are created by positioning
standard units side by side in a coordinated way.
The switchgear is manufactured and tested in the
production facility
.
Operation and maintenance manual
This manual contains instructions on how to replace
the sensors in the UniSec Digital version and the
main indications concerning the user interface.
