This project is for our customer Tractebel, with Elia as end customer. Since the AIS station 70 kV Beerse was outdated, it was converted into a 70 kV GIS (Gas Insulated Switchgear) system with nine fields. The scoop 70 kV consisted of equipping the new building, a completely new LV installation, cable works to connect the GIS in the relevant fields and the demolition of the old AIS (Air Insulated Switchgear) 70 kV station. Also some replacements and harmonisations were performed on the 150 kV part of Beerse. These new power units were installed. For the 150 kV part a new cabin is built with double bus bar.
