Cable Structure

      • Copper wire bare, stranded
      • Wire structure:
      • 0.5 mm²: 7 x 0.3 mm
      • 1 mm²: 7 x 0.43 mm
      • Core insulation: halogen-free polymer
      • Core identification: colour coded, per bundle:
      • Pair no. 1: a-core = blue; b-core = red
      • Pair no. 2: a-core = grey; b-core = yellow
      • Pair no. 3: a-core = green; b-core = brown
      • Pair no. 4: a-core = white; b-core = black
      • Cores stranded in pairs with optimal lay lengths, 4 pairs stranded into bundles with optimal lay lengths, bundles stranded in layers with optimal lay lengths
      • Bundle identification: synthetic helix with printed digits
      • Foil wrapping
      • Drain wire, tinned copper, stranded (0.5 mm² = 7 x 0.3 mm)
      • Screen: plastic-coated aluminium foil (St), approx. overlap 25%
      • Outer sheath: halogen-free polymer
      • Sheath colour: grey (RAL 7032)

Properties

      • halogen-free
      • pair stranding with short and varied lay lengths within a bundle, leads to good crosstalk attenuation values

Tests

      • corrosiveness of combustion gases acc. to DIN VDE 0482-754-2 / DIN EN 60754-2 / IEC 60754-2
      • bundle fire test acc. to DIN VDE 0482-332-3-24 / DIN EN 60332-3-24 / IEC 60332-3-24
      • smoke density acc. to DIN VDE 0482-1034-1+2 / DIN EN 61034-1+2 / IEC 61034-1+2
      • certifications and approvals:
      • EAC

Notes

      • the conductor is metrically (mm²) constructed, AWG numbers are approximated, and are for reference only
      • 2-pair cables: cores stranded to a star quad

Application

      • Halogen-free data transmission cables are used in measurement and control technology for the transmission of digital and analogue signals up to a frequency of 10 kHz. These cables are used inside buildings and outdoors, however, not without UV protection.
