PE Insulated Air Core/Jelly Filled Paired Railway Signalling Cables (RF 0.3)

PE Insulated Air CoreJelly Filled Paired Railway Signalling Cables RF 0.3

Application The cables are designed to give good protection to the cable cores against inductive interference (RF=0.3). 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
Twisted Pairs: Two insulated conductors are twisted into pairs with varying lays to minimize crosstalk
Cable Core Assembly: The cores are cabled together in concentric layers to form the cable core. Units are identified by colour coded binders
Core Filling (optional): The cable core interstices can be filled with petroleum jelly to avoid longitudinal water penetration inside the cable
Core Wrapping: One or more non-hygroscopic polyester tapes are helically or longitudinally laid with an overlap
Moisture Barrier (optional): An optional copolymer coated aluminium tape of 0.2mm is applied longitudinally with an overlap
Bedding: PE or LSZH
Electrostatic Screen: Corrugated copper tape of 0.12mm is applied longitudinally with overlap
Electrostatic Armour: Two high permeability steel tapes of 0.5mm are helically applied with gap. The outer tape will cover the gap left by the inner one
Sheath: PVC/LSZH
Ripcord: Nylon ripcord may be placed parallel to the cores to facilitate sheath removal
