Motion plastics specialist, igus, has more than 25 years’ experience developing and producing cables for moving applications. Over 2 billion double strokes are carried out in its 2,750m2 test lab each year. This week’s video of the week shows the 7 basic rules for good dynamic motion cables.

  1. Strain-relieving core: a genuine centre cord is essential, providing protection for the stranded structure during moving applications.
  2. Conductor structure: stranding material must be optimised to cope with the most demanding applications.
  3. Core insulation: high quality, proven insulation materials such as PVC or TPE offer support for the stranded wires.
  4. Cable core: individual conductors should be bundled in groups, then cabled together around the core, a design optimised to deal with compressive and tensile forces.
  5. Inner jacket: a gusset-filled extruded inner jacket helps maintain cable core integrity better than filler or fleece, providing a continuous base for the shield.
  6. Shield design: high-quality, optimised angle braided shield protects the cable from external interference, as well as shielding cable interference into the outside environment.
  7. Outer jacket: the outer jacket must be resistance to UV rays, oils and chemicals, as well as wear and abrasion.
