PE Insulated Air Core/Jelly Filled Star Quad Railway Signalling Cables (RF 0.1) |
|
| |
| Applications |
|
| |
The cables are designed to give good protection to the core against inductive interference (RF=0.1).The cables are used for outdoor signaling equipment. |
| Standards |
| |
• RENFE E.T. 03.365.051.6 |
| Construction |
|
| |
| Conductors: Solid annealed bare copper 0.9/1.4mm as per ASTM B-3/class 1 of IEC 60228. |
|
| Insulation: Solid polyethylene as per ASTM D 1248/IEC 60708. |
| Cabling Element: Four insulated conductors are twisted together to form a quad. |
| Cable Core Assembly: The cores are cabled together in concentric layers to form the cable core. Units are identified by colour coded binders. |
| Core Wrapping: One or more non-hygroscopic polyester tapes are helically or longitudinally laid with an overlap. |
| Electrostatic Screen: One layer of copper wires 0.12mm is applied helically. |
| Bedding: PE or LSZH. |
| Electrostatic Armour: Two steel tapes of 0.5mm are helically applied with gap. The outer tape will cover the gap left by the inner one. |
| Sheath: PE, PVC or LSZH. |
| Ripcord: Nylon ripcord may be placed parallel to the cores to facilitate sheath removal. |
