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.

Standard

• CEI 20-11
• CEI 20-14
• CEI 20-29
• CEI 20-34
• CEI 46-4
• CEI 103-10

Cable 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.
