Contains the turbine, the AC generator and the condenser, plus additional safety equipment: averages 300-500 km of cables per unit.
LV XLPE cables and connectivity
- Copper (or aluminum) XLPE energy cables
- Connect the generator to the HV transformer
- Nexans produces connectors, as well as cable joints and terminations.
These cables are widely used around the world by conventional electrical generating systems.

Fire-retardant and fire-resistant cables
- Energy cables (up to 1 kV) prevent fire propagation and dramatically reduce smoke emission
- LV power for alarms, smoke evacuation, lighting, sprinklers and equipment during a fire.
Nexans is providing energy cables for Areva’s III-generation EPR reactors now being built in Flamanville (France).

Control/instrumentation/ sensor cables
- To control the pressure and temperature of the steam going to the high-pressure and low pressure turbine elements, and other systems, including the condenser and heaters
- They can be nuclear-qualified, according to customer requirements.
Nexans has provided these cables for both Ling Ao 1 +2 (China), Temelin 1+2 (Czech Republic), and other projects.

VDI (Voice-Data-Image) fiber cables
- Increasingly, surveillance and control are being integrated on one platform.
- Several digital Video-Over-IP cameras, using a fiber link, replace expensive CCTV cameras.
Special zero-halogen sheaths assure operational continuity during a fire.
