  • Excellent flexibility
  • Water resistant and flame retardant
  • Temperature range -25°C to + 90°C. For fixed installation lowest temperature is -40°C
  • UV, sunlight, ozone, oil resistant
  • Ink jet printed for easy identification


  • Heavy duty flexible cables are suited for use medium mechanical stress specially for the connection of
    submersibe motor pumps for construction site drainage down to a water (clean or dirty) depth of about 10m,
    in some cases may by use up to 500m (without approvals) and the maximum water temperature upt o 40°!C.
  • The cables may be rated 0,6/1 kV where the installation has been built in protection and for motors lifting
    appliances-machine tools etc.
  • Other industrial applications
