Nexans has developed and tested a new generation of medium voltage cables called EDRMAX specifically designed to connect renewable power sources to the grid.
The company, which collaborated on the project with the utility managing the majority of France’s public electricity distribution network, said the cable allows easier installation compared to the previous EDR version, particularly in challenging conditions like hard or rocky ground.
Nexans said EDRMAX is compliant with the NFC 33-226 standard and is available in single or three-core versions, with either aluminium or copper conductor.
The oversheathing of the cable enables it to be buried directly into the ground with no need for an additional sand layer, the company said.
It added that the joule losses have been reduced compared with the existing EDR cables.
Nexans is manufacturing the new cable at its Bourg en Bresse facility in France.
