Application
The cables are used as railway cables and can be installed directly into the ground or in ducts.
Reference Standards
Cable Construction
| Conductors |
Soft annealed solid copper, 0.9/1.4 mm nominal diameter. |
| Insulation |
PE. |
| Cabling Element |
Four insulated conductors are twisted together to form a quad. |
| Stranding |
Quads are helically stranded in concentric layers. |
| Core Wrapping |
Two or more layers of plastic tape(s) with overlapping. |
| Screen |
0.9/1.2/1.4/1.8mm copper wires wrapping with one plastic tape (protection against interference). |
| Inner Sheath |
LSZH sheath, coloured green. |
| Armour |
Two layers of steel tape (0.8mm thick). |
| Outer Sheath |
LSZH sheath, coloured green. |
