The rise of renewable energy sources makes research into efficient power cables key, according to manufacturer Nexans, which celebrates the tenth anniversary of its research centre in Lyons, France this week.

Thomas Hähner, Manager at the Nexans Research Centre told ELN energy efficiency is an “important part” of research into developing different cables for the renewable energy sector. He added research was essential to keep up with the market which can change within a couple of years.

At the centre Nexans also tests prototypes of cables for wind turbines to see if they can withstand being twisted several times each way along with the blades. On offshore wind turbines, cables need to be strong enough to do this for up to 20 years.

Researchers also test cables for solar photovoltaic and hydro generators as well as the offshore oil and gas sector.
