-S(H145)-S(H95).jpg)
Application
The cables are designed for transmission of service tensions up to 600 VDC /420 Veff AC100Hz in railway signalling networks, and are suitable for installation in ducts or laying directly into the ground.
Standards
● Dlk 1.013.107y
● Dlk 1.013.107y
● Dlk 1.013.108y (for 1.4/1.8mm conductor H95 type)
● Dlk 1.013.110y
Construction
Conductors
Solid annealed copper, 0.9, 1.4 or 1.8 mm nominal diameter.
Insulation
Solid polyethylene.
Stranding
Single conductors are helically stranded in concentric layers. Cables from 14 conductors on have two extra conductors of 0.5mm with perforated insulation (surveillance conductors).
Core Wrapping
Plastic tape(s) with overlapping.
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
Two helically applied steel tapes (0.5 or 0.8mm thick, depending on required reduction
factor).
Outer Sheath
Low density polyethylene.
Type Codes
