Electricity distribution and transmission stations Serpollet renovates and installs new high voltage transformer stations up to 225Kv. The stations are for the use of public organizations like E.R.D.F (French electricity board) and industrial companies which require them. Our offering includes electrical engineering including : electrical engineering surveys (drawings, wiring diagrams, layouts, design calculations) ; earthing circuits ; installation, connection and if required the possible provision of transformers and high voltage equipment ; low voltage connections and control-command ; commissioning assistance. This activity is complemented by the provisioning of civil engineering services. civil engineering surveys (drawings, design calculations) ; building of civil engineering structures (transformer pits and benches, offset pits, concrete supports for frameworks and switchgear, heavy and light tracks, drainage, low voltage raceways, etc.) ; earth moving. We also propose customers a fault clearance service for their high and low voltage installations.
