Ordering Information

 PE Insulated Air Core/Jelly Filled Star Quad Railway Signalling Cables (RF 0.1)

Application

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

Telephone Cables

Telephone 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

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
