　　2、敷设时环境温度≥0℃。3、小弯曲半径：4、无铠装层电缆，应不小于电缆外径的6倍。5、有铠装或铜带屏遮结构电缆，应不小于电缆外径的12倍。6、有屏遮结构的软电缆，应不小于电缆外径的6倍。电力铁路专用电缆1、产品执行标准：GB参照采用IEC227，耐电压优于IEC227），GA阻燃型）。

过载保护过载保护原理可简单表述如下：假设电路允许的小通过电流为Imin，大电流为Imax，保护的器件电流为I，I2表示在规定时间范围内，保护器件有效工作的小电流，那么我们可得出公式Imax≤I≤Imin1）I2≤1.45Imin2）值得注意的是，多种因素都会对电流产生一定的影响，如温度、多芯电缆、机床设备的安装密度等，因此要想机床设备正常工作，必须要保护器件的电流大于小电流，并在大于大电流时执行保护。
