TABLES / EXPLANATIONS AWG-SIZESMinimum bending radiiIf the bending radii are smaller than those permitted,a reduced service life can be expected depending onthe stress conditions. The values given in table 4/14should be taken as a basis.The minimum bending radii are shown as the productof the overall diameter of the cable and a factor,which is dependent on the diameter of the cable(e.g.: 3 x d).The minimum permissible bending radii are validwithin the specified ambient temperature range(see thermal parameters, page 4/14) subject to theprovision that the permissible tensile loads are notexceeded (see mechanical parameters, page 4/16).In critical cases, the cable manufacturer should beconsulted.Minimum pemissible bending radii RFlexible cablesCORDAFLEX, PLANOFLEX, SPREADERFLEX,PROTOLONPROTOLONRated voltage Up to 600 V Above600 VMaximum overall diameter of thecable or maximum thickness ofthe flat cable (mm) / (inches)Fixed installationUp to 8/0.315Above 8/0.315 to12/ 0.472Above 12/0.472 to20/ 0.787Above 20/0.787OPTOFLEXminimumper missiblebendingradiusmm /inches3 x d 3 x d 4 x d 4 x d 6 x d 125 /4.921Fully flexibleoperation3 x d 4 x d 5 x d 5 x d 10 x d 125 /4.921Table 4/14For the entry,e.g. at a centrefeed pointFor forced guidancewith reelingoperationFor forcedguid ance withfestoon operationFor forced guidancewith powertracksFor forcedguid ance withsheavesFor forced guidancewith cabletendersMinimum distancewith doubleor S-type directionalchanges3 x d 4 x d 5 x d 5 x d 10 x d 250 /9.8425 x d 5 x d 5 x d 6 x d 12 x d 250 /9.8423 x d 4 x d 5 x d 5 x d 10 x d 125 /4.9214 x d 4 x d 5 x d 5 x d 10 x d 125 /4.9217.5 x d 7.5 x d 7.5 x d 7.5 x d 15 x d 250 /9.8427.5 x d 7.5 x d 7.5 x d 7.5 x d 15 x d 250 /9.84220 x d 20 x d 20 x d 20 x d 20 x d 50 x d
