Product Overview
Application:
Engineered for dynamic torsion applications in wind turbines, these 0.6/1kV multi-core power cables transmit energy from generators to transformers. They withstand continuous twisting stresses in free-hanging vertical installations within turbine towers, ensuring reliability in onshore/offshore wind farms.
Compliance:
Manufactured to IEC 60502 standards for low-voltage power distribution in renewable energy systems.
