Presentation Notes

Nexans spans the full range of applications in Energy networks, both subsea, terrestrial and aerial : - Power Transmission cables - Power Distribution Cables - Power Accessories (for interconnections,…) - Industrial Special Wires and Cables� Electricity will be the principal source of power in the third millennium. By introducing new technologies, Nexans can help to optimize network reliability and create new economic opportunities. Fibre optics, for instance, can be alongside power lines to create a communications network. Key concerns : Value for money, responsiveness and quality of service.

LV Distribution LinesABC technology Advantages

ABC cables are cheaper compared to buried cablesUse of relatively low cost Aluminium instead of CopperProvide a better security compared to bare overhead lines OHL

Reduced risk of electrical shocks in case of human contact (insulated conductors)

Reduced safety distances between buildings and other lines Higher protction against contact (birds, trees) Earthing of the messenger in case of failure Reduced risk of fire in case of broken lineLess overloading due to non-adherence of ice in winter

Use of superior insulation (XLPE) compared to traditional PVCEasy to install and light to handle (a wide range of accessories)Easy maintenance and repair in case of failure or accident
