APPLICATION

The cables are designed for transmission of low frequent signals up to 90 KHz through symmetric circuits in railway networks, and are suitable for laying directly into the ground or in ducts.

STANDARD

  • Dlk 1.013.109y

  • Dlk 1.013.110y

CABLE CONSTRUCTION

  • Type CodesConductors: Solid Annealed copper, 0.9 or 1.4 mm nominal diameter.

  • Insulation: Solid polyethylene.

  • Cabl ing Element : Four insulated conductors are twisted together to form a quad.

  • Stranding: Quads are helically stranded in concentric layers. Cables from 7 quads on, have two extra conductors of 0.5mm with perforated insulation (surveillance conductors).

  • Core Wrapping: Plastic tape(s) with overlapping.

  • Moisture Barrier: One laminated sheath made of aluminium tape (0.15mm) coated with PE-Copolymer on at least one side is applied with longitudinally overlap.

  • Inner Sheath: Low density polyethylene.

  • Electrostatic Shield: One layer of helically applied copper wires (0.9, 1.2, 1.4 or 1.8mm).

  • Electromagnetic Shield: One helically applied steel tape (0.2-0.3mm) or two helically applied steel tapes (0.1mm).

  • Outer Sheath: Low density polyethylene.

  • AJ– outdoor cable with protection against inductive infl uences

  • 2Y solid PE conductor insulation

  • (L)2Y inner laminated PE sheath

  • B steel tape armor

  • 2Y outer PE sheath

  • S signal cable

  • LG layer stranding

  • H(n) operating capacity

RING MARKING OF QUAD

The single core is identifi ed by black ring markings:

  • Side Circuit 1 a-wire without marking, b-wire 1 mark distance 17mm

  • Side Circuit 2 a-wire 2 marks distance 34mm, b-wire 2 marks distance 17mm
