• Studies and Production of fammily cables and harnesses: Low Voltage, high Voltage, VVDC, AuxPower, CanBus,All DCS (cooling, Opto-services, Tmod), Environment NTC, TempPP2

• Specific production of 300 tools for type2 and type3 connectors at SMGOP (Fontaine F38600)

•EDMS documentation on services

•Global layout of IBL cables

•Services coordination
