Special Features

  • 900 Microns Tight buffered fibres support fast field installations.
  • Reduce installation time and costs.
  • Easy jacket removal using standard tools.
  • Flexible and Fire retardant Inner & outer sheath with aramid yarns and Glass Yarn as tensile elements helps in easy installation in space constrained areas.
  • LSZH sheath makes cable suitable for higher fire safety requirement.
  • Small cable diameter & lightweight.
  • Requires no grounding or bonding due to all‑dielectric construction.
