Helukabel has introduced Heluwind WK 137-Torsion FT4, a wind turbine cable that is specially designed for torsional application in cable loops and successfully passed the challenging CSA FT4 flame test.
Heluwind WK 137-Torsion FT4 has UL-, CSA-, RoHS- and CE-approval, VDE and WTTC are in preparation. The torsion application of +/-150? per 1m was tested in more than 16,000 cycles in the 27 ft high HELUKABEL research tower that reproduces 1:1 construction and conditions of the cable loop within a wind tower. The operating temperature range is -40?C to +90?C (UL: +80?C). Due to its specially formulated jacket compound the Heluwind WK 137-Torsion FT4 successfully passed tests for the aggressive oil effectively used in wind power turbines. That jacket material also provides a higher abrasion resistance. The Heluwind cable is UV- and seawater resistant and qualifies for offshore-installation.
