Renewable power from the wind, reliable cables from Alpha Wire

Alpha Wire offers cables with an unmatched combination of performance, reliability, and quality to keep turbines delivering energy day in and day out.

Xtra-Guard® 4  performance cable withstands the temperature extremes of the wind turbine environment. Its durable construction offers three times the low-temperature flexibility of ordinary PVC, provides good resistance to oils, solvents, chemicals, and fuels, and is approved for wind turbine tray cable (WTTC) applications.

Xtra-Guard Flex Torsion  cable withstands continuous flexing, including multiaxis torsional movements, making it an excellent choice for wind vanes and anemometers that experience random movement.

Xtra-Guard Flex Motor Supply   cable combines excellent flexibility in a tough abrasion and oil-resistant design with a diameter smaller than most comparable motor supply cables—making it well suited for the tight spaces in wind turbines for connecting AC drives, servo drives, and variable-frequency drives. cable combines excellent flexibility in a tough abrasion and oil-resistant design with a diameter smaller than most comparable motor supply cables—making it well suited for the tight spaces in wind turbines for connecting AC drives, servo drives, and variable-frequency drives.

Series M  flexible control cables are used for stationary/cable tray and for light to moderate flexing applications. With MTW and WTTC approvals, Series M cables offer excellent resistance to oil, chemicals, and sunlight.flexible control cables are used for stationary/cable tray and for light to moderate flexing applications.

Series V VFD  cable is designed specifically for the needs of variable-frequency drives, combating the continuous dielectric stresses, with no degradation under heavy electrical load or voltage irregularities.cable is designed specifically for the needs of variable-frequency drives, combating the continuous dielectric stresses, with no degradation under heavy electrical load or voltage irregularities.

Instrumentation  cables are available in a wide range of configurations for monitoring and telemetry needs.
