交联聚乙烯绝缘架空电缆:90℃。
Max. permissible continuous temperature :
PVC、PE insulated aerial cables :70℃;
XLPE insulated aerial cables:90℃。
● 短路时(长持续时间不超过5秒)电缆导体的温度:
聚氯乙烯绝缘架空电缆:160℃;
聚乙烯绝缘架空电缆:130℃;
交联聚乙烯绝缘架空电缆:250℃。
Max. short-circuit temperature of the conductor shall not exceed:
PVC insulated aerial cables :160℃;
PE insulated aerial cables :130℃;
XLPE insulated aerial cables:250℃。
● 电缆敷设时环境温度应不低于-20℃。
The installation ambient temperature should not below -20℃。
● 电缆的允许弯曲半径:
电缆外径(D)小于25mm时,应不小于电缆外径的4倍;
电缆外径(D)等于或大于25mm时,应不小于电缆外径的6倍。
The bending radius of cables are recommend as follows:
When the diameter of cables less than 25mm:not less than 4 times the diameter of cables;
When the diameter of cables not less than 25mm:not less than 6 times the diameter of cables。
● 当电缆使用于交流系统时,电缆的额定电压至少应等于该系统的额定电压;当电缆使用于直流系统时,该系统的额定电压应不大于电缆额定电压的1.5倍。
When the cables use in alternating current system,rated voltage of cables should be at least equal the rated voltage of the system;When the cables use in direct current system,rated voltage of the system should be not greater than 1.5 times of the rated voltage of the cables。
