UIC Data Bus 0.75mm²
Two foam skin insulated tinned copper stranded conductors are twisted together with two filling elements to a pair.

Wrapping: Overlapped plastic-foil(s).
Screen: Tinned copper wire braid screen
Element sheaths: TPE.

Stranding
4 strands are twisted to a core together with 3 cored element, the UIC data bus and two fi llers

Core Wrapping
Overlapped plastic-foil(s).

Outer Sheath
Cross-linked oil resistant LSZH compound.

For 11 cores UIC databus cables:

4 cores
