  • Stranding:
    < 7 cores: cores stranded in a layer with
    optimal lay length around a filler as per
    ≥ 7 cores: cores stranded with optimal
    lay length to bunch-construction with
    low torsion strength, optimal selected
    short lay length around a filler
  • Outer sheath of special PUR extruded
    extruded as filler with pressurea
  • Sheath colour: black (RAL 9005)
  • With meter marking
  • Low-adhesion
  • Halogen-free
  • High property of alternating bending
  • High tensile strength, abrasion- and impact
    resistance at low temperature
  • Use in multi-shift operations under
    extremely high continuous bending loads
  • Abrasion resistance
  • Tear resistance
  • High stability
  • Oil resistance
  • Better chemical resistance
  • UV and ozone resistance
  • Higher economical solution
  • Reduced Ø, therefore less moving masses

Application HELUKABEL® MULTISPEED®-TRONIC-PUR installed there, where the extreme requirements for the cables are necessary. The selected materials and lay-up technique permit these high flexible cables for permanent application in drag chains for long distances, high and low speed of movements. These cables are installed in dry, moist and wet rooms and in open air with free movement without tensile stress or forced movements. These robust and abrasion resistant special control cables are installed there, where the problems appear for the application in permanent stresses
e. g. in energy drag chains, industry robotics, production lines, automatic control systems and permanent movable machinery parts for multi-shift operation. These cables are installed everywhere, where high requirements for the flexibility, abrasion, oxygen and chemical resistance are necessary. For applications which go beyond standard solutions (for example for composting appliances or high shelf conveyors with extremely high processing speeds etc.) we recommend for our especially developed enquiry sheet for energy guiding systems. Before installation in cable trays please read the instructions. Further technical details see selection table for drag chain cables, see chapter "Technical Informations".
CE = Product conforms with Low-Voltage Directive 2014/35/EU.
