The cables are designed to give good protection to the core against inductive interference. The cables are used for outdoor signaling equipment.
• VDE 0816/DIN 57816
Solid annealed bare copper 0.9/1.4mm as per ASTM B-3/IEC 60228 Class 1
Solid polyethylene as per ASTM D 1248/IEC 60708
Four insulated conductors are twisted together to form a quad
The cores are cabled together in concentric layers to form the cable core. Units are identified by colour coded binders
One or more non-hygroscopic polyester tapes are helically or longitudinally laid with an overlap
Copper tape or copper wire braid with wire diameter of 0.12mm
PE or LSZH
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
PE/PVC or LSZH
Nylon ripcord may be placed parallel to the cores to facilitate sheath removal
