Chainflex® cables - igus® - #50

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