4、电缆的允许弯曲半径
(1)额定电压0.6/1KV电缆:
电缆外径小于25mm者,应不小于4D;
电缆的外径D为25mm及以上者,应不小于6D。
(2)额定电压U(Um)为10(12)kV电缆:
单芯电缆应不小于20(D+d);
多芯电缆应不小于15(D+d);
其中:
D——电缆的实际外径(mm);
d——电缆导体的实际外径(mm)。

5、系统额定电压Systemratedvoltage
额定电压为0.6/1kV,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。
当系统的工作电压应不大于系统额定电压的1.1倍。
额定电压为10kV架空绝缘电缆可用于单相接地故障时间,每一次一般不大于1min的系统。
也可用于最长每次不超过8h。
每年累计不超过125h的系统。
Whenthecablesuseinalternatingcurrentsystemwithratedvoltage0.6/1.0kV,ratedvoltageofcablesshouldbeatleastequaltheratedvoltageofthesystem;

6、电缆运输和保管要求
电缆盘不允许平放。
运输中严禁从高处扔下装有电缆的电缆盘,严禁机械损伤电缆。
电缆如果需要分段使用,电缆分段后必须用防水封帽将电缆头密封,防止进水。
