Chainflex cables

The Energy Chain System ® was filled with many different igus ® Chainflex ® cables, e.g. the CF9.60.05Result regarding 1:No or only barely measurable traces of abrasion could bedetected on the highly abrasion-resistant TPE outer jacket.This means that a failure due to abrasion or jacket breakagedespite extreme environmental factors (temperature differences,UV irradiation, etc.) is not to be expected.Result regarding 2:The overall stranding structure showed – due to the gussetfilledextruded outer jacket – no indications of fatigue and hadnot changed in its pitch length.Due to the large share of talc, no abrasion was determinedbetween the TPE-insulated cores. The high-voltage tests alsodid not show any age-related changes.Result regarding 3:The cable was opened all the way to the copper conductorin the most stressed section of the radius.Here too, after more than 40.000 km, the inspection of theindividual wires also showed no fatigue breakages whichwould indicate an early failure of the cable.To sum up, it can be said that this cable, which was used ina real crane application in the second trolley of an STS crane,is still completely intact even after more than 40.000 km andthat preventive repair work is not required.An igus ® energy supply system with an approx. length of 26 min a stainless steel trough with middle band support.The individual elements of the CF9 from the cable piecedissected for the test setup.Product informationCF9 page 80A close-up of the completely intact copper conductor. Theinspection performed over the entire length shows that theconductor is still completely intact and does have anyindividual wire breakages.47
