Halogenfree Control Cables LiHCH
The cables are used in wind turbines. Among other things the cable connects switchgear in top of the turbine with switchgear in the tower. Notice that the cable has to twist on the free hanging part
Halogenfree insulation compound Colour Code: As required
Low Smoke Zero Halogen compound Colour code: Black Ral 9005
Conductor identification:
Conductors have to be identified with a color code (as required) or Black identified with printed numbers (with or without Yellow/Green)
Cable marking:
CABLOSWISS – Week/Year of production - WINDLINK LiHCH n x/G yy mm2 Metric
Where: n: number of conductors x/G: without/with Yellow/Green conductor yy: section of conductor
The cable has to be oil resistant. Test according to EN60811-2-1 (based on to IEC60811-2-1)
2 times 4 hours at 70°C in oil IRM 902 After 4 hours the cable shall be checked for damage to the isolation. If still ok the test will continue 4 hours more with a final examination of the isolation.
Max tensile strength variation: +/- 40% (HD22.1, table 2, ref no 1.4.2)
Elongation: +/- 40% (HD22.1, table 2, ref no 1.4.3)
The cable has to have low emission of smoke. Smoke visibility according to EN50268 (based on IEC61034) Level for smoke visibility is >60%
The cable has to be halogen free, have low emission of corrosive gases and acid.
Halogen free – without Chlorine, Fluorine and Bromine
Corrosive gases and acid content according to HD22.13 and EN50267-1 and EN50267-2 (based on IEC60754)
Cable has to resist 2000 Twist cycles [+/- 150°/m] at any temperature within the temperature range.
(Info.: The turbines twist the cable +/-4 turns on 10 m cable)
