Insulated Aerial Cable Standerd:GB/T12527-2008 CCC compulsory certification,ISO9001-2000,ISO14001 Voltage rating:600/1000V Remark: 1.For the PVC/PE insulated ,the highest allowed operating temperature of conductor for long-term working is 70°c,while for theXLPE insulated. the temperature is no more than 90°c. 2.In short-circut(max.long-term is no more than 5 seconds):for the PVC inaulated,The highest temperature for conductor is no more than160°c. PE no more than 130°c,XLPE no more than 250°c. 3.The environment temperature should be no lower than -20°c when lay. 4.The bending radius of cables are recommended as follows: when the diameter of cables less than 25mm:not less than 4 times the diameter of cables; when the diameter of cablesmore than 25mm:not less than6 times the diameter of cables. 5.when cable use in in AC system,rated voltage of cables should be at leastequal the rated voltage of the system:When in DC system, should be not greater than 1.5 times of the rated voltage of the cable. Application: used in urban,rural power distribution network.safe and simple. (cable,power cable,electric cable,power wire,elctric wire,PVC cable ,XLPE cable,CU/AL cable)
