Nexans Opens the Latest High Voltage Test Laboratory at its Calais Center of Excellence
The new enlarged Center is now fully operational, with the capacity to test cable systems up to 1.5 million volts.
Paris La Défense, November 22, 2017 – The high voltage (HV) market is requiring an increasing number of tests at higher and higher voltage levels. In order to support this growing business, Nexans has decided to significantly enhance its testing capacity by building in Calais, France, a new state-of-the-art direct current (DC) laboratory that allows to test simultaneously three independent qualification loops.
Each loop is composed of multiple cable sections and joints and is connected to the electrical network through two terminations. It is designed to represent the various configurations existing in power grids. The generators, rated for voltages up to 1.2 million volts, operate in a controlled environment, which guarantees the optimum equipment availability required for performing ageing tests typically lasting more than one year.
This new laboratory is dedicated to HVDC cables, a market of primary importance for high-capacity links and connection of renewable energy sources, such as the Dolwin 6 offshore windpark. For this large project brought to life by TenneT, Nexans Germany was recently awarded a contract to supply and install two 90-km-long HVDC cables that will transport up to 900 MW of wind power, enough to transmit enough electricity for almost one million German homes.
12 HV test laboratories supported by multidisciplinary experts
The Calais Center of Excellence for HV testing occupies 6,500 m² and is now composed of 12 HV test laboratories equipped with world-class generators operating up to 1.5 million volts. It is COFRAC-certified (ISO 17025) and addresses both alternating current (AC) and DC applications. The Center of Excellence is a critical asset for qualification of the cable systems developed by Nexans for its customers and for supporting the Group’s industry-renowned innovation program. The Center played a key role in qualification of Nexans’ 500 kV AC and 525 kV DC systems.
In addition to electrical testing, highly skilled and experienced experts of the Calais Center of Excellence perform electrical, thermal and mechanical modeling along with physico-chemical analyses and thermo-mechanical tests. Such in-depth approach allows to develop a detailed understanding of phenomena involved in HV cable systems, both resistive and superconducting, in order to ensure that Nexans cables and accessories will meet customer needs at commissioning and in the long run. Finally, the teams of the Calais Center of Excellence contribute to continuous improvement of installation techniques as well as technical training of Nexans’ customers and partners.
“As the global energy needs continue to grow, the world will require extremely reliable cable systems for power transmission at ever higher voltage levels for both AC and DC applications”, said Dirk Steinbrink, Nexans’ Senior Executive Vice President, High Voltage and Underwater Cable Business Group. “With its new laboratory, the Calais Center of Excellence will be positioned as one of the leading hubs for helping our clients address the challenges of the future.”
Nexans sikrer tilgangen til energi gennem sit store og varierede udbud af kabler og kabelløsninger, som forbedrer vores kunders aktiviteter og resultater verden over. Nexans’ ambition er at være en samarbejdspartner, og en støtte for kunderne inden for fire hovedforretningsområder: elektrisk transmission og distribution (til havs og på land), energiressourcer (olie og gas, minedrift og vedvarende energikilder), transporter (veje, jernbaner, fly og skibe) samt installation (kommercielle bygninger, boliger og datacentraler). Nexans’ strategi bygger på en løbende innovation af produkter, løsninger og tjenester, kompetenceudvikling for medarbejdere, uddannelse af kunder og introduktion af sikre industriprocesser med mindst mulige miljøpåvirkning. I 2013 blev Nexans den første virksomhed i kabelindustrien, der oprettede en fond til fremme af langsigtede projekter, som giver udsatte samfund rundt om i verden tilgang til energi. Med en industriel tilstedeværelse i over 40 lande og salgskontorer over hele verden havde Nexans 26.000 medarbejdere og en omsætning på 5,8 milliarder euro i 2016. Nexans er børsnoteret på NYSE Euronext Paris, afdeling A. For mere information besøg www.nexans.dk.
