EUROBALISE BGA
Application
The cables are used as balise cables for ERTMS (European Rail Traffic Management System) railway networks.
The cables are armoured and can provide low reduction factor.
Standards
CEI 20-11
CEI 20-14
CEI 20-29
CEI 20-34
CEI 46-4
CEI 103-10
Construction
Conductors: Solid annealed copper, 1.6 mm nominal diameter.
Insulation: Solid polyethylene.
Stranding: Conductors will be stranded with dielectric fi llers in order to get a circular core shape.
Core Wrapping: Plastic tape (s) with overlapping.
Inner Sheath: Low density polyethylene.
Screen: Aluminium/polyethylene tape longitudinally applied and overlapped.
Drain Wire: Tinned copper drain wire
Intermediate Sheath: Low density polyethylene.
Armour: Two galvanized steel tapes.
Outer Sheath: Low density polyethylene.
