Elgin, Ill.-based HELUKABEL USA, a manufacturer and supplier of wires, cables and cable accessories, has introduced a wind turbine cable designed for torsional application in cable loops. The cable has successfully passed CSA FT4 flame test.
The HELUWIND WK 137-Torsion FT4 is a halogen-free and flame-retardant cable with a superior twisting and flexing performance, according to the company. The torsion application of +/-150 degrees per meter was tested in more than 16,000 cycles in the 27-foot-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 degrees C to + 90 degrees C (UL: +80 degrees C). The HELUWIND WK 137-Torsion FT4 successfully passed tests for the aggressive oil used in wind power turbines. That jacket material also provides a higher abrasion resistance and, therefore, a longer lifetime than rubber cable, according to the company. In addition, the HELUWIND cable is UV- and seawater resistant and qualifies for offshore-installation.
