Flexibility

To respond to growing demand and provide uninterrupted power to customers, networks need to accommodate energy from any source, including minigrids, photovoltaic rooftop arrays, fuel cells, or windparks.

Centralized generation and control need to give way to distributed generation and intelligence so that power can be exchanged on the open commodity market.

• Nexans makes it possible for you to adapt load management through real time temperature rating systems for cables. Cable Distributed Temperature Sensing uses optical fiber units in the surrounding sheath to determine temperature profiles, detect hotspots (due to hot water pipes, etc.), and control and monitor cable load. Temperature measurement is possible at 2 meter intervals over a 30 km length of cable.

• To assure operational flexibility for overhead lines, Nexans offers a range of high-capacity conductors and accessories for the most varied climatic conditions. Aluminum Conductor Steel Supported (ACSS) cables eliminate sag at very high temperatures (250°C). Hundreds of kilometers have been provided to European and North-American Transmission System Operators.

• Temporary construction site cables are HV replacement cables that are used during the maintenance, repair and modification of your overhead lines, transformers and substations. They provide a temporary “bridge” or a source of emergency power. They can either be purchased or rented, and allow you to reduce outages and increase the availability of all your network assets.

• A Nexans retrofitting solution saves civil engineering, installation costs and the time required to expand your network. Existing pipes for housing fluid-filled cables are re-used to accommodate next-generation XLPE cables. With a range of high-voltage cables available, a power transmission network can continue to grow flexibly according to actual power needs, and in a sustainable way.

• When you do a repair, you want to have exactly what you need when you need it. Nexans provides MV customized accessory kits on site for greater flexibility. They contain all needed equipment and preconnectorized, pre-cut cables needed to splice in replacement cable or make a connection. This decreases outage time, and lowers the risk of error and repeat failures.
