PE Insulated Air Core/Jelly 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:

Telephone CablesTelephone Cables

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 or LSZH

Ripcord: Nylon ripcord may be placed parallel to the cores to facilitate sheath removal
