Cable Construction

UIC

For 9 cores UIC databus cables:

  • 4 cores: 10 mm² stranded tinned copper conductor with LSZH insulation.
  • Combined Element: 3 cores (with Cu-strand 2×6mm², 1×2.5mm²) are twisted with a fi lling element to a combined element. Wrapping: Overlapped plasticfoil(s). Elements sheaths: TPE
  • UIC Data Bus 0.75mm²: 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 mm² stranded tinned copper conductor with LSZH insulation.
  • Combined Element: 5 cores (with Cu-strand 2×6mm², 1×2.5mm² and 2×1.0 mm²) are twisted with a fi lling element to form a combined element.
  • Wrapping: Overlapped plastic-foil(s).
  • Elements sheaths: TPE.
  • UIC Data Bus 0.75mm²: Two foam skin insulated tinned copper r stranded conductors are twisted together with two fi lling elements to a pair.

For 18/20 cores UIC databus cables:

  • Star Quad: Four LSZH insulated 1mm² stranded tinned copper conductors are twisted to form a star quad.
  • UIC Data Bus 0.75mm²: Two foam skin insulated tinned copper stranded conductors are twisted together with two fi lling elements to form a pair.
  • Wrapping: Overlapped plastic-foil(s)
  • Screen: Tinned copper wire braid screen
  • Element sheaths: TPE.
  • Wrapping: Overlapped plastic-foil(s)
  • Stranding: 4 star quads are stranded together with 2 or 4 UIC data bus cable and several fi llers.
  • Core Wrapping: Overlapped plastic-foil(s).
  • Screen: Tinned copper-wire braid screen.
  • Outer Sheath: Cross-linked oil resistant LSZH compound.
