GKN+ 3 X 25/25 Curm stranded 0.6/1 kV

The Nexans GKN+ Cu three-core cable is a new-generation low-carbon cable designed to deliver performance, durability, and reduced environmental impact. Manufactured in Switzerland, it stands out thanks to a fully recycled outer sheath and conductors containing 10.4% recycled copper. It also integrates Metrium, an intelligent and precise marking system that indicates the remaining cable length in real time, simplifying installation and optimising on-site monitoring. Thanks to its cross-linked HEPR insulation, the GKN+ Cu cable ensures high robustness as well as excellent mechanical and thermal performance.
