摘　　要：卷绕动力电缆是电源点(移动式设备为地面接线箱)向堆取料机等移动式设备提供动力电源的主要设备,正确计算并合理选择才能保障设备的正常运行。从堆取料机额定工作电流和最大电流(尖峰电流)的计算、堆取料机机上工作面变压器的计算与选择入手,计算移动式设备中卷绕动力电缆的载流量,选择卷绕动力电缆的截面,并从电缆短路热稳定条件方面进行校验。The winding power cable is the major equipment to provide power for movable equipment like the stacker / reclaimer from the power supply point（which is the ground connection box for movable equipment）.The normal operation of equipment requires correct calculation and reasonable selection.Starting with the calculation of rated operational current and maximum current for the stacker / reclaimer,and calculation and selection of transformers on the working face of the reclaimer,the carrying capacity of winding power cable is figured out,to select the cross-section of winding power cables, with checking for thermal stability condition of cable short circuit.
