Cable Structure
-
- Copper wire bare, stranded
-
- Wire structure:
- 0.5 mm²: 7 x 0.3 mm
- 1 mm²: 7 x 0.43 mm
-
- Conductor insulation: halogen-free polymer
-
- Conductor identification: color coded, per bundle:
- Pair No. 1: conductor a = blue; conductor b = red
- Pair No. 2: conductor a = gray; conductor b = yellow
- Pair No. 3: conductor a = green; conductor b = brown
- Pair No. 4: conductor a = white; conductor b = black
-
- Conductors 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
-
- Foil wrap
-
- Drain wire, tinned copper, stranded (0.5 mm² = 7 x 0.3 mm)
-
- Shield: plastic-coated aluminum foil (St), approx. overlap 25%
-
- Outer jacket: halogen-free polymer
-
- Jacket color: gray (RAL 7032)
Properties
-
- halogen-free
-
- pair stranding with short and varied lay lengths within a bundle, leads to good crosstalk attenuation values
Tests
-
- combustible gas corrosiveness acc. to DIN VDE 0482-754-2 / DIN EN 60754-2 / IEC 60754-2
-
- bundle fire test acc. to DIN VDE 0482-332-3-24 / DIN EN 60332-3-24 / IEC 60332-3-24
-
- smoke density acc. to DIN VDE 0482-1034-1+2 / DIN EN 61034-1+2 / IEC 61034-1+2
-
- certifications and approvals:
- EAC
Notes
-
- the conductor is metrically (mm²) constructed, AWG numbers are approximated, and are for reference only
-
- 2-pair cables: conductors stranded in a star quad
Application
-
- Halogen-free data transmission cables are used in measurement and control technology for the transmission of digital and analogue signals up to a frequency of 10 kHz. These cables are used inside buildings and outdoors, however, not without UV protection.
