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.
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.
IMoisture Barrier
One laminated sheath made of aluminium tape (0.15mm) coated with PE-Copolymer on at least one side is applied with longitudinally overlap.
Outer Sheath
Polyethylene, with reinforced radial thickness.
Type Codes
A– outdoor cable
2Y- solid PE conductor insulation
(L)2Yv- laminated sheath with increased wall thickness
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
