Chainflex cables

Varied and extreme temperature curves thereby served forthe simulation of environmental influences, particularly whenthe temperature plunged during downtimes from plus degreesto -40 °C in the shortest time and the motion was restartedafterward.Under these application conditions, the dampening of thecable also should not rise above 3 dB at 850 nm wave length.After one million double strokes, which correspond to an operationalperformance of about 7000 kilometres, the maximumdampening is reached and still remains significantly below 3 dB.The measurements highlighted in the diagram reveal thatdistinct variations in temperature combined with the constantmovement in the E-Chain ® have only minor effects on thedampening of the CFLG.6G.TC cable.The noticeable high initial dampening is attributed to the plugsused and also reflects the reality here because, in practice,90 % of the cables used in automation are pluggable fibreoptic cables.Product informationCFLG.G page 164The test with the igus ® cable makes it quite clear that onlyrealistic and absolutely very expensive tests can fetch clarityabout the service life of cables.Dampening of the fibres 1-6 of the CFLG.6G.50/125.T cable in two directionsDampening in [dB] at 850 nmFibre no. 1, direction 1Fibre no. 2, direction 1Fibre no. 3, direction 1Fibre no. 4, direction 1Fibre no. 5, direction 1Fibre no. 6, direction 1Fibre no. 1, direction 2Fibre no. 2, direction 2Fibre no. 3, direction 2Fibre no. 4, direction 2Fibre no. 5, direction 2Fibre no. 6, direction 2Temperature in °C(number of double strokes)after 5 daysat restBEFORErestartafter 5 daysat restAFTERrestart41
