EUROBALISE BGA Railway Signalling Cable

Application

The EUROBALISE BGA Railway Signalling 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.
