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 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.
