一、本產(chǎn)品適用于交流額定電壓0.6/1KV及以下的電力系統(tǒng)中，作輸配電能用。產(chǎn)品除具有聚氯乙烯絕緣電纜已有的優(yōu)良性能外，還具有柔軟、易彎曲等特點(diǎn)。

二、使用條件Working Condition

1、電纜的導(dǎo)體長(zhǎng)期允許zui高工作溫度為70℃；Max temperature of cable conductor for Long-term working is 70℃.

2、電纜敷設(shè)時(shí)zui低環(huán)境溫度為0℃；Min. environment temperature for installing cableis 0℃.

3、電纜允許彎曲半徑：非鎧裝電纜不小于電纜外徑的8倍；鎧裝型電纜不小于電纜外徑的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、短路時(shí)（zui長(zhǎng)持續(xù)時(shí)間不超過(guò)5S），電纜導(dǎo)體的zui高工作溫度為160℃； Max. working temperature of cable conductor is 160℃ during short circuit(the longest lasting time shall be no more than 5 seconds).

三、電纜近似外徑及載流量Approximate outer diameter and current-loading capacity of cable

 與同規(guī)格的普通聚氯乙烯絕緣聚氯乙烯護(hù)套電力電纜相比，電纜的外徑一般增加：導(dǎo)體截面為95mm2及以下，外徑增加2~10mm；導(dǎo)體截面為120mm2及以上，外徑增加12~20mm；電纜的重量一般增加4%~10%。軟電力電纜允許的載流量可參照同規(guī)格VV系列電力電纜的載流量值，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、交貨長(zhǎng)度

根據(jù)雙方協(xié)議，允許任何長(zhǎng)度的電纜交貨。長(zhǎng)度計(jì)量誤差不超過(guò)±0.5%。
