一、本產品適用于交流額定電壓0.6/1KV及以下的電力系統中,作輸配電能用。產品除具有聚氯乙烯絕緣電纜已有的優良性能外,還具有柔軟、易彎曲等特點。
二、使用條件Working Condition
1、電纜的導體長期允許zui高工作溫度為70℃;Max temperature of cable conductor for Long-term working is 70℃.
2、電纜敷設時zui低環境溫度為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(zui長持續時間不超過5S),電纜導體的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
與同規格的普通聚氯乙烯絕緣聚氯乙烯護套電力電纜相比,電纜的外徑一般增加:導體截面為95mm2及以下,外徑增加2~10mm;導體截面為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、交貨長度
根據雙方協議,允許任何長度的電纜交貨。長度計量誤差不超過±0.5%。
