Chainflex cables

Test 1:Inspection of four differentcable designsFour different cable constuctions has been analyzed:Test item A – conductor with special conductor alloyTest item B – conductor same as test item A, but in copperTest item C – conductor in braided structureTest item D – conductor in stranded constructionThis long-term inspection, which was carried out over aperiod of 2 years, provided the following results:Test item ATest item BTest item CTest item DNumber ofdouble strokes47.434.277450.000638.0002.350.000Crosssection7x0,207x0,207x0,257x0,25d [mm]5,85,67,37,3Testradius3,1xd = 183,2xd = 182,5xd = 182,5xd = 18Test 2:Two different cable designs were tested, whereby different corenumbers and cross-sections were selected in comparison withtest 1:Test item A – conductor with special conductor alloyTest item B – conductor in copperIn this case, test item B was manufactured completely identicalto test item A except for the conductor material.The test showed that not a single case of wire breakage couldbe detected for test item A even after 28 million double strokes.Test item B, however, only achieved approx. 1,4 milliondouble strokes before complete destruction of the conductorwas determined. This test also demonstrates that the alloyconcept clearly surpasses the life of the copper conductor bymore than 19 times and achieves these extraordinary resultsin the mechanically critical area of very small cross-sections!Number ofdouble strokesTest item A 28.267.000Test item B 1.450.000Crosssection2x0,142x0,14d [mm]3,92,9Testradius4,6xd = 186,2xd = 18Number of double strokesNumber of double strokesTestradiusTest item A3,1xdTest item B3,2xdTest item C2,5xdTest item D2,5xdTestradiusTest item A4,6xdTest item B6,2xdConductivity of alloysHowever, the outstanding mechanical properties of thisalloy have to do with a reduced conductivity versus copper,which can be compensated by means of slightly increasedcross-sections. This means that the cross-sections mentionedin the catalog meet the electrically defined cross-sectionsdefined using the conductivity value. The conductor diameterof the alloyed conductor increases slightly compared to theconductor diameter of a copper conductor.This compromise results in a 10% greater external diameterfor the CF98 series versus a comparable CF9 type, althoughthe service life differences to be expected betweenthe CF98 versus the CF9 speak for themselves and increaseby a multiple factor in comparison with other so-calledchain-suitable cables.As in the case of the CF9 series, further characteristics ofthe Chainflex ® CF98 include the highly abrasion-resistant,gusset-filled extruded TPE outer jacket, the oil resistanceand the UV resistance as well as the absence of any PVCand halogen compounds. Especially in areas of applicationthat only possess minimum construction space but alsodemand a large number of strokes, the igus ® cable offersan increased degree of operational safety and efficiency.Areas of application are available in the semiconductor andcomponent parts industry, in the automation sector as wellas in the automotive and bank sector. New possibilities ofapplication can also be found in automatic doors for motorvehicles and trains as well as in automatic food and selfservicemachines and in the packaging industry.31
