1. Conductor
  • Flexible plain copper "FSC" better than IEC 60228 class 5.
2. Insulation
  • Inner semi-conductive layer.
  • New special insulation compound EPDM, better than DIN VDE 207 part 20.
  • Outer semi-conductive layer, easy strip design.
3. Protective Earth Conductor
  • Flexible plain copper "FSE" better than IEC 60228 class 5.
4. Ground Check Conductor (Pilot Core) 5. Inner Sheath Special Synthetic Rubber, better than GM1b. 6. Reinforcement
  • Synthetic threads with very high tensile strength as a protection against twist stress and pressure loads.
7. Outer Sheath
  • New special sandwich construction for optimum flexibility, abrasion resistance and heavy load special rubber compound.
8. Color
  • Red
Flexible reeling cable for power supply to machines with high and extreme mechanical stress. e.g:
