Cable Structure
- Copper wire bare, stranded
- Strand construction:
- 0.5 mm²: 7 x 0.3 mm
- Core insulation: semirigid PVC
- Core identification: colour coded, per bundle:
- Pair no. 1: a-core = blue; b-core = red
- Pair no. 2: a-core = grey; b-core = yellow
- Pair no. 3: a-core = green; b-core = brown
- Pair no. 4: a-core = white; b-core = black
- Cores stranded in pairs with optimal lay lengths, 4 pairs stranded into bundles with optimal lay lengths, bundles stranded in layers with optimal lay lengths
- Bundle identification: synthetic helix with printed digits
- Drain wire, tinned copper, stranded (0.5 mm² = 7 x 0.3 mm)
- Screen: plastic-coated aluminium foil (St), approx. overlap 25%
- Outer sheath: PVC
- Sheath colour: see datasheet
- Length marking: in metres
Properties
- the materials used during manufacturing are cadmium-free, contain no silicone and are free from substances harmful to the wetting properties of lacquers
- pair stranding with short and varied lay lengths within a bundle, leads to good crosstalk attenuation values
Tests
- flame-retardant acc. to DIN VDE 0482-332-1-2 / DIN EN 60332-1-2 / IEC 60332-1-2
- certifications and approvals:
- EAC
Notes
- the conductor is metrically (mm²) constructed, AWG numbers are approximated, and are for reference only
- 2-pair cables: cores stranded to a star quad
- with blue sheathing for the installation of intrinsically safe systems (ignition protection type -i-) in explosion-endangered areas according to DIN VDE 0165-1 / DIN EN 60079-14 / IEC 60079-14, Section 16.2.2
Application
- RD data transmission cables are used in measurement and control technology, as well as in control stations of industrial plants. The cables are used for the transmission of analogue and digital signals up to a frequency of approximately 10 kHz. They are suitable for fixed installations inside buildings.
