Cable structure
  • Bare copper conductor, single-wire
  • Core insulation of PE (2Y)
  • Core identification of quads marked with
    black rings
  • 4 cores twisted to a star quad
  • 5 star quads stranded to sub units,
    each 5 or 10 sub units stranded to main
    units and the sub or main units stranded
    to cable core
  • Core cavities continuously filled
    with petrol-jelly
  • Core wrapping with paper tape
  • Outer sheath, as laminated sheath (L)2Y,
    PE-coated aluminium tape spliced with
    PE (2Y) sheath
  • Sheath colour: black
  • Sheath marking continuously with
    telephone-receiver, meter marking
    in white colour
  • These cables are not allowed for power
    installation or applications requiring high
    current levels. Due to their PE outer sheath,
    these cables are also not permitted for fire
    and hazardous areas without any protective

These external subscriber telephone cables are installed as telecommunication connection cable for connecting the telephone extension to the telephone exchange for transmitting signals. These subscriber connecting cables are suitable for laying in under ground, in cable ducts and cable conduits. According to DIN VDE 0800 part 1, these cables are allowed in all types of installation plants. The cavities of the cable core, filled continuously with viscous compound (F). Both sides of PE-copolymere coated aluminium type (L), which is spliced with the outer PE-sheath, ensures a barrier against water vapour and crosswise and longitudinal water tightness. Black coloured PE-sheath is UV-resistant. The Polyethelene material (PE 2Y) is halogen-free.
CE = The product is conformed with the EC Low-Voltage Directive 2006/95/EC.
