This extruded inner jacket both ensures that the insulated conductors are efficiently guided, as well as maintaining the integrity of the cable core and providing a continuous surface for the overall shield. 6. Shield design A high-quality braided shield provides electomagnetic interference (EMI) protection for the cable. An optimized braid angle prevents the shield strands from breaking over the linear axis and increases torsional stability. The shield has an optical coverage of approximately 90%, providing maximum shield effectiveness. 7. Outer jacket The outer jacket material must be resistant to UV radiation, abrasion, oils, and chemicals, as well as being cost- effective. However, the outer jacket of a cable for dynamic applications must be resistant to abrasion, and remain flexible while providing support. For best wear rates and service life, the outer jacket should be extruded under pressure. When you implement a continuous-flex cable designed with these guidelines in mind, you can dramatically increase the service life of your machine, and reduce the risk of unexpected downtime due to cable failures.
