GKN+ Flex 3x50/50 mm2 Cu

Name: GKN+ Flex 3x50/50 mm2 Cu
Availability: InStock

The Nexans GKN+ Flex Cu three-core cable is designed to offer high flexibility and significantly easier installation. Thanks to its class 5 copper conductors, the force required to bend the cable is significantly reduced, improving handling during installation, especially in tight angles and constrained routing. It incorporates recycled copper conductors, contributing to the reduction of the CO₂ footprint, as well as a 100% recycled PE sheath.
