Capacity increase solutions
When your network is overcongested, Nexans can perform computer simulation in order to identify bottleneck locations and supply load monitoring solutions. If this is not enough, Nexans proposes the replacement of saturated cables with cables that carry more energy.
Dig into your untapped reserves with Dynamic Line Rating solutions
Nexans provides Dynamic Line Rating for overhead transmission lines. This technology allows utilities to know the true transmission capacity in real time, it increases transmission capacity significantly for over 90% of the time, and protects the transmission lines from overheating and sagging beyond safety limits.
Nexans has installed the system for over 100 utility customers, including Manitoba Hydro (Canada), Kansas City Power and Light (USA), RTE (France) and REE (Spain). Installations with ONCOR (USA) within the framework of the American Recovery and Reinvestment Act of 2009, has been shown to improve market efficiency by unlocking usable transmission capacity and increase reliability by augmenting situational awareness.
The Oncor Smart Grid Demonstration project in the USA has already saved millions of dollars in congestion in Texas’ real time wholesale electricity market. With a new forecasting system, DLR benefits will extend beyond real time to “day of” and “day ahead” operations.
Increase grid capacity with Nexans Lo-Sag® technology.
After successful installation in Brazil with our customer LIGHT, RTE , France’s electricity transmission system operator (TSO), is trialing a new type of overhead power line using Nexans’ carbon fibre composite technology in Haute-Vienne, in the Limousin region.
With the advantage of reduced capital investment compared to entirely rebuilding the line, these new carbon core conductors are lighter and offer higher mechanical strength compared to standard conductors.
They can be designed to operate at higher temperatures, thus allowing temporary or permanent increase in capacity, and improving the overall reliability of the network.
This innovation provides TSOs with opportunities to adapt their high- and extra-high voltage networks to meet the needs of tomorrow’s energy landscape for redistribution of power generation, especially with the development of renewable energy resources.
Transport electricity over longer distances with HVDC
High-voltage DC cables deliver high power capacity over longer distances, in both terrestrial and submarine conditions.
Nexans HVDC submarine cables are connecting Northern Ireland and Scotland, while another cable runs under the Channel between Dover and Calais. An Integrated Return Conductor eliminates the magnetic field, thus protecting the marine environment.
