Integrated 9/11/18/20 Cores 0.75mm^2 UIC Databus Cables

Application

The cables are used as connecting cables to transmit digital signals inside railway rolling stocks.

Standard

• DIN 5510-1

Cable Construction

For 9 cores UIC databus cables:

• 4 cores: 10 mm^2 stranded tinned copper conductor with LSZH insulation.
• Combined Element: 3 cores (with Cu-strand 2×6mm^2, 1×2.5mm^2) are twisted with a fi lling element to a combined element. Wrapping: Overlapped plasticfoil(s). Elements sheaths: TPE
• UIC Data Bus 0.75mm^2: Two foam skin insulated tinned copper stranded conductors are twisted together with two fi lling elements to a pair.
• Wrapping: Overlapped plastic-foil(s).
• Screen: Tinned copper wire braid screen
• Element sheaths: TPE.
• Wrapping: Overlapped plastic-foil(s).
• 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: 10 mm^2 stranded tinned copper conductor with LSZH insulation.
• Combined Element: 5 cores (with Cu-strand 2×6mm^2, 1×2.5mm^2 and 2×1.0 mm^2) are twisted with a fi lling element to form a combined element.
• Wrapping: Overlapped plastic-foil(s).
• Elements sheaths: TPE.
