Description

Description

Standards

  • Product
    HD 603; IEC 60228
  • National
    ASE

Applications

This family is designed for underground low-voltage networks requiring high reliability:

Underground low-voltage distribution networks

  • Installation in ducts, cable trenches, cable trays and direct burial
  • Electrical substations
  • Infrastructure requiring service continuity and reliability

Key advantages

  • Class 5 copper conductor
  • 100% recycled sheath, significantly reducing environmental impact
  • 10.4% recycled copper in the conductor
  • Reduces CO₂ emissions by 9% to 17%
  • HEPR insulation providing excellent mechanical and thermal performance
  • Full transparency through the PEP Ecopassport
  • Low sheath shrinkage / high abrasion resistance
  • Halogen-free

By choosing the GKN+ Flex Cu single-core, you opt for a durable, high-performance cable aligned with modern carbon footprint reduction requirements without compromising reliability.
