Wind Energy Cables

Reliable Cabling for Harsh Wind Environments

Wind turbines are installed in some of the world's most demanding environments — from hilltops and deserts to seashores and offshore platforms. These locations expose systems to intense UV, mechanical stress, moisture, and extreme temperatures.

AEROLEX Wind Energy Cables are engineered to thrive under these harsh conditions, delivering durability, flexibility, and long-term performance. Installed in nacelles, towers, or turbine bases, these cables ensure seamless power transmission and signal integrity in both onshore and offshore wind energy installations.

Key Features

High Flexibility & Torsion Resistance: Specially designed for dynamic bending and twisting in moving parts such as nacelles and pitch control loops.
UV & Weather Resistant: Built to withstand prolonged exposure to harsh environmental conditions including sunlight, rain, and salt spray.
Oil & Chemical Resistance: Excellent durability against mineral oils, synthetic lubricants, hydraulic fluids, cleaning agents, and coolants.
Temperature Resistant: Stable performance from -40°C to +105°C, with short-circuit resistance up to 250°C.
Environment Friendly: Made with halogen-free, low smoke, and recyclable materials for safer and greener installations.

Applications

Nacelle-to-Rotor Cable Connections
Tower Internal Wiring
Pitch and Yaw Control Systems
Generator and Transformer Interconnections
