"Our main objective as E.DIS Netz GmbH is to supply our customers with energy reliably and around the clock. Sustainability also plays an increasingly important role in this, which is why we will increasingly evaluate new, SF₆-free alternatives. I am looking forward to the further cooperation with Nuventura to make our network future-proof and at the same time ensure a reliable and sustainable energy supply."
Andreas Freygang
Project Manager, E.DIS
"We really like the innovative ideas and solutions of Nuventura for an SF6-free medium-voltage-switchgear from environmental and economic points of view. With this solution service-friendly and reliable switchgears with innovative and clever solutions for safe operation will be available."
Bastian Wölke
Engineering MV-Switchgear, Westnetz GmbH
"What convinced us about nuventura's switchgear are its compact dimensions, which are very similar to those of the classic SF6 GIS, as well as the high degree of flexibility and automation that enable us to connect our newly constructed PV park, our battery storage and the electrolyzer."
Jörn Hennig
Head of Engineering, APEX Energy Teterow
