PE Insulated Air Core/Jelly Filled Star Quad Railway Signalling Cables to VDE 0816/DIN 57816
Application
The cables are designed to give good protection to the core against inductive interference. The cables are used
for outdoor signaling equipment.
Standards
VDE 0816/DIN 57816
Construction
Conductors
Solid annealed bare copper 0.9/1.4mm as per ASTM B-3/IEC 60228 Class 1
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
Copper tape or copper wire braid with wire diameter of 0.12mm
Bedding
PE or LSZH
Electrostatic Armour
Two steel tapes of 0.5mm or 0.8mm 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
