Cable structure

• Bare copper conductor, multi wires
• Conductor construction:
  0,5 mm² = 7×0,3 mm
  1 mm² = 7×0,43 mm
• Core insulation of halogen-free
  polymer compound
• Core identification coloured
  pair-no.1: a-core = BU; b-core = RD
  pair-no.2: a-core = GY; b-core = YE
  pair-no.3: a-core = GN; b-core = BN
  pair-no.4: a-core = WH; b-core = BK
• Cores twisted in pairs, with short lay length
  (approx. 20 pitch/m ≙ 50 mm)
• 4 pairs stranded to a unit
  (unit labelled with numbers
  printed plastic helix)
• Units stranded in concentric layers
• Foil wrapping
• Electrostatic screen of plastic coated
  aluminium foil and drain wire tinned, 0,5 mm²
• Outer sheath of halogen-free, polymer
  compound, flame resistant
• Sheath colour: grey (RAL 7032)

Properties

• The static screen protects the transmission
  circuits against outer electrical interferences
• The halogen-free cables prevent the fire
  propagation and compared to PVC cables
  exist only a low smoke density under flame
  influence
• This results no decomposition products which
  destroy equipments, machines and buildings
  by corrosion

Tests

• Flame test acc. to
  DIN VDE 0482-332-3 / BS 4066-3 /
  DIN EN 60332-3 / IEC 60332-3
• Corrosiveness of combustion gases
  acc. to DIN VDE 0482-267 /
  DIN EN 50267-2-2 / IEC 60754-2
• Smoke density acc. to
  DIN VDE 0482-1034-1+2 / BS 7622-1+2
  DIN EN 61034-1+2 / IEC 61034-1+2

Note

• AWG sizes are approximate equivalent
  values. The actual cross section is in mm².

Application

The halogen-free data transmission cable RD-H(St)H are used for measurement and control technology for transmission of analog and digital signals up to frequencies of approx. 10 kHz. The twisted pairs with short pitches (<50 mm for 0,5 mm²) and different lay lengths which lead good cross-talk attenuation values in a unit. These cables are used in inside buildings (in special cases in open air, but with sufficient protection against sunlight is necessary).
CE = Product conforms with Low-Voltage Directive 2014/35/EU.
