Eiffage Énergie Systèmes carries out major electrical works in René Dubos hospital complex, Pontoise

From February 2018 onwards, they are to change the high-voltage substations and configure the substitution loop enabling the electrical circuit to be diverted in the event of a loss of power supply.
In this manner they will replace a general electrical distribution substation configured in double supply with looped connection, the central switching station supplying generating units 1 and 2, a second switching station supplying generating unit 3, and a third substation wholly dedicated to supplying power to the surgical medical centre.

Our teams will also install a low-voltage master distribution board - Service index IS 233 shape 4b - and a 1,250 kVA liquid-immersed transformer (cooled in a dialectric oil-based liquid).
To complete this complex installation process, a 2,000 amp busduct will be created and put into use, in order to link the low-voltage master distribution board and the BT3-BT4 substations.
