Medium Voltage rubber Flexible Cable for reeling Applications

  • Flexible cable designed for high mechanical stresses, especially for applications with frequent winding and unwinding with concurrent tensile and torsion stress. The cable is used for conveyors, container cranes,
  • Specially designed flexible reeling cable with optimised 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.
