The Sauges and Gorgier tunnels equiped by Schneider Electric
Schneider Electric in Switzerland took part in a project for 14 km of highway in Switzerland. This section is the most important in terms of work because it includes two major tunnels, the Sauges (2 km) and Gorgier (3 km) tunnels, as well as a semi-covered (1.5 km) portion (1.5 km). It includes major innovations in electro-mechanical equipments and electrical distribution.
Schneider Electric was selected from among other companies because it was the only manufacturer to automatically provide the technical characteristics of its equipment, thus enabling the engineering firm to perform a preliminary study.
Plus, another major innovation: the use of an Intranet network. The project manager's concept was to be able to control and see installations from any location. Thanks to this network, maintenance personnel can now control or have a look at tunnel installations at any time with a laptop computer.
