igus has more than 25 years’ experience developing and producing cables for moving applications. Over 2 billion double strokes are carried out in its 2750m2 test lab each year. Here the company sets out the seven basic rules for good dynamic motion cables.
Strain-relieving core: a genuine centre cord is essential, providing protection for the stranded structure during moving applications
Conductor structure: stranding material must be optimised to cope with the most demanding applications
Core insulation: high-quality, proven insulation materials such as PVC or TPE offer support for the stranded wires
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
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
Shield design: high-quality, optimised angle braided shield protects the cable from external interference, as well as shielding cable interference into the outside environment
Outer jacket: the outer jacket must be resistance to UV rays, oils and chemicals, as well as wear and abrasion
