Chainflex cables

The new igus ® development of a twistable, shielded singlecorecable picks up on this point and ensures, due to its specialdesign and understucture of the shield, that no forces atall or that only the smallest possible forces act on the shieldwire.As the described test clearly shows, massive service life extensioncan, for example, be determined when compared to aCF310.250.01.Test rig:The new cable CF ROBOT was tested at the igus ® laboratoryon a specially developed rig for torsion test.The torsion angle thereby amounts to ±270° for a total cablelength of about 2,5 m (tested in different versions of theTriflex ® R).Fitted for the test were:n 3 CF ROBOT cables 037n 3 cables of the series CF310.250.01.ULn 3 cables of the series CF310.250.01Picture 1: damaged overall shield sample of the braid versionafter 250.000 movements.The detail inspection of the shield braid shows distinct damageon the shield wires.The analyzed samples (Picture 2) of the CF ROBOT (so farsamples were taken after 250.000, 1,5 million and 3 millionmovements). 037 show no damage in the area of the cableor the overall shield even at above 3 million torsional movementsof ± 270°.Picture 2: The CF ROBOT shows absolutely no damage aftermore than 3 million movements.The detailed analyses (Picture 3) of the shield wires, bufferfibres, PTFE film and the cable show no apparent wear outs.The test is carried out further to determine the maximum servicelife of the cable.igus ® test lab: The cables were tested in movements of± 270°.The initial test sample of the CF310 with braided shield andthe CFROBOT were taken after 250.000 movements with atorsion angle of ± 270°.The analyses (cable taken apart) were undertaken in threepart areas respectively of the cable length.In the sample illustrated in Picture 1, distinct damage to theoverall shield are noticeable in the upper third of the cabletaken apart.Picture 3: detail pictures of the CFROBOT after more than3.0 million movements of ±270°.43
