Seven basic rules for good 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
