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.
