3x70

Application

This cable is specially designed for Wind Turbines and to be used for the Loop .

Maximum torsion stress ± 150°/meter ( ± 100°/meter for 400mm²) 
 - Standard test : 2000 cycles
-  Results : No copper wire broken

The quality of material used for insulation and sheathing and high quality copper conductors make the cables both flexible, durable, resistant to torsion and to high temperatures. Nexans offers more than a decade of experience in the wind energy market. Our expertise makes WINDLINK® cables highly recommended for wind turbines.
