Application
These cables with increased tolerance to torsion application, improved behaviour against abrasion and extended temperature, UV and ozone resistant are specially designed for wind turbines.
Standards
HD 22.12
UL/CSA 22.2
UL 758
Construction
Conductor: Flexible annealed bare copper, class 5 according to IEC/EN 60228.
Insulation: Special cross-linked EI7 rubber for high temperatures (EPDM class 28). Special thermoset EPR for high temperature can be offered upon request.
