一、本产品适用于交流额定电压0.6/1KV及以下的电力系统中，作输配电能用。产品除具有聚氯乙烯绝缘电缆已有的优良性能外，还具有柔软、易弯曲等特点。

二、使用条件Working Condition

1、电缆的导体长期允许zui高工作温度为70℃；Max temperature of cable conductor for Long-term working is 70℃.

2、电缆敷设时zui低环境温度为0℃；Min. environment temperature for installing cableis 0℃.

3、电缆允许弯曲半径：非铠装电缆不小于电缆外径的8倍；铠装型电缆不小于电缆外径的20倍；Bending radium allowed by cable:It will be no less than 8 times that of cable O.D for inarmored cable and 20 times that of cable O.D for ar-mored cable.

4、短路时（zui长持续时间不超过5S），电缆导体的zui高工作温度为160℃； Max. working temperature of cable conductor is 160℃ during short circuit(the longest lasting time shall be no more than 5 seconds).

三、电缆近似外径及载流量Approximate outer diameter and current-loading capacity of cable

 与同规格的普通聚氯乙烯绝缘聚氯乙烯护套电力电缆相比，电缆的外径一般增加：导体截面为95mm2及以下，外径增加2~10mm；导体截面为120mm2及以上，外径增加12~20mm；电缆的重量一般增加4%~10%。软电力电缆允许的载流量可参照同规格VV系列电力电缆的载流量值，下降6%~10%。

By comparing with common power cable of the same specification with PVC insulation and sheath, cable outer diameter is bigger by 2~10mm for cable with cross sec-tion of 95 95mm2 or lower and by 12~20mm for cable with cross section of 120 mm2 or higher. And cable weight generally remains heavier by 4%~10%. About current-loading capacity allowed by soft power cable, you can refer to that of VV series power cable of the same specifi-cation with a drop of 6%~10%.

四、交货长度

根据双方协议，允许任何长度的电缆交货。长度计量误差不超过±0.5%。
