Thermal parametersThe different temperature limits of the individualflexible electric cables for cranes and materialhandling equipment are summarized in table 4/11.Under no circumstances may the values shown beexceeded due to interaction of internal Joule heatand the ambient temperature. If cables are exposedto radiation, e.g. sunlight, the temperature of theouter sheath of the flexible electric cable can rise toa level which is significantly higher than the ambienttemperature. This situation must be compensated forby corresponding reduction of the current-carryingcapacity. The temperatures on the surface of thecable are limits for the ambient temperature.All insulating and sheathing compounds of the flexibleelectric cables become stiffer as the temperaturedrops. If the temperature falls below the specifiedlimit, a point can be reached below which thecompounds used become brittle.In addition to this, more force (sometimes considerablymore) is needed for bending a flexible electric cabledue to the increase of stiffness of the insulating andsheathing compounds at lower temperatures. Thiscan create problems in the use of flexible electriccables for cranes and material handling equipment(e.g. with the reel drive).Temperature limitsFlexible cables Type Temperature limit during operation, storage, installation andtransport (°C)of the conductorduringoperationof the conductorduringshort-circuiton the surfaceof the cable,fixed installationon the surfaceof the cable,fully flxibleoperationCORDAFLEX(SM) /-RS NSHTÖU 90 250 -50 to + 80 -35 to + 80PLANOFLEX NGFLGÖU 90 250 -50 to + 80 -35 to + 80CORDAFLEX(K) NSHTÖU 90 250 -50 to + 80 -35 to + 80SPREADERFLEX YSLTÖ 70 150 -20 to + 60 -20 to + 80OPTOFLEX - - -40 to + 80 -20 to + 80PROTOLON(FL) / FO NTSFLCGEWÖU 90 250 -50 to + 80 -35 to + 80PROTOLON(SM-R) / FO NTSKCGEWÖU 90 250 -50 to + 80 -35 to + 80Table 4/11
