1.The maximum rated temperature
The maximum operating temperature of cores shall not exceed 90℃ when the cable is used for long period. The temperature of cores shall not exceed 250℃ at short circuit for 5 seconds.
2、安装要求 Installation requirement
电缆敷设时不受落差限制，敷设时环境温度不低于0℃，电缆允许弯曲半径不小于电缆的直径10倍。对通交流的单芯电缆，要求采用非铠装或采用钢丝铠装，同时不允许敷设在磁性管道中。
The installation of cables is not limited by the difference of level along the route. The ambient temperature should not be below 0℃ during installation. The permissible bending radius for cable shall not be less than 10 times of the cable diameter. The single cable shall be without amour or with steel wire amour when it is electrified with alternating current and shall not be laid in magnetic ducts.
