Applications :

• 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.

Standards :

• Dlk 1.013.109y
• Dlk 1.013.110y

 

Construction :

• Conductors : Solid Annealed copper, 0.9 or 1.4 mm nominal diameter.
• Insulation : Solid polyethylene.
• Cabling 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.
• Electromagnetic Shield : One helically applied steel tape (0.2-0.3mm) or two helically applied steel tapes (0.1mm).
• Outer Sheath : Low density polyethylene.

Type Codes :

• A–	outdoor cable
  2Y	solid PE conductor insulation	S	signal cable
  (L)2Y	PE inner laminated sheath	LG	layer stranding
  B	steel tape armor	H(n)	operating capacity

• Ring marking of Quad
  The single core is identified 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
