Medium Voltage Rubber Flexible Cable with Integrated Fiber-Optics(FO) for Reeling

Specially designed flexible reeling cable with reduced dimensions for extremely high mechanical stresses occur in applications with monospiral reels and cylindrical reels, very high reeling speed, torsional stress. Also for connection of large material handling machines such as excavators, dumpers, crushers in open-cast mines. For use in wet or dry conditions, in industrial units, in underground and open-cast mining, in explosion-risk areas.
