護膚品概述Introduction 　　該商品是在緊壓的銅、鋁導體擠制內屏蔽了了了層和耐候熱塑聚乙稀或耐候型灰色高密集度計算聚乙稀絕緣性性層和外屏蔽了了了層而制成(1kV空架絕緣性性拖鏈電纜沒縱向 屏蔽了了了層)，組成簡略、安全可靠管理安全可靠，同一又兼備良好的機械化高中物理特性和高壓電器特性，耐電痕、耐沿面釋放、耐大氣質量特性良好，與祼電纜線相較，敷設 油隙小，不浪費的行為火車方式過道，火車方式電壓電流降縮小到，非常是降低供電公司交通事故再次發生，有效確保什么是人生安全可靠管理。 　　The products are manufactured by extruding a conductor screen layer, an insulated layer of rough-weather-adaptive XLPE or rough-weather-adaptive black HD-PE or PVC, and an insulation screen layer over the compacted copper/aluminium conductor(no conductor screen layer and insulation screen layer for cables of rated voltage 1kV),with the advantage of simple construction, and excellent mechanical,physical and electrical property as well as fine performance of anti-creeping- discharge, rough-weather-adaptive and creepage-proof. Compared with bare conductor, the product can be laid more closely to save the line gallery, and have less voltage-drop. Above all, the products installed reduce power accidents to insure lives safety. 　　物品規則Standard 　　本物品按GB12527-90、GB14049-93做產生。 　　The products shall comply with the standards GB12527-90 and GB14049-93. 　　應用面積Applications 　　本廠品支持于多層住宅建筑施工群、文旅規劃設計區及林木多叢沿海地區的1kV、10kV、35kV直埋輸供電層面。 　　The products fit for transmitting line and distributing line of rated voltage 1kV, 10kV and 35kV in tall buildings, traveling development area and wooded tract. 　　采用基本特征Operating characteristics 　　1、 電力電纜額定容量額定電流U0/U包含八種：a.0.6/1kV b. 10kV c.. 35kV。 　　The rated voltage of cable has three classes: 　　2、 低壓電纜導體的繼續不可以運行溫： 　　Continuous permissible operating temperature: 　　聚氯氯乙烯絕緣電阻為70℃; 　　PVC Insulation:70℃ 　　聚丁二烯絕緣電阻為70℃; 　　PE Insulation: 70℃ 　　高溶解度聚丁二烯為75℃; 　　HDPE Insulation: 75℃; 　　交連聚乙稀隔絕為90℃; 　　XLPE Insulation: 90℃; 　　3、 斷路時(長持續保持準確時間不超5秒)，低壓電纜的溫度過高度： 　　Max.Temperature of cable under short-circuit(5sec.Max.Duration) 　　聚氯氯乙烯電絕緣為160℃; 　　PVC Insulation: 160℃; 　　聚丁二烯隔熱為130℃; 　　PE Insulation: 130℃ 　　高容重聚氯乙烯為150℃; 　　HDPE Insulation: 150℃; 　　交連聚乙稀絕緣電阻為250℃; 　　XLPE Insulation: 250℃; 　　4、 電纜電線的敷設溫度表應不不超-20℃。 　　Laying temperature of cable not less than -20℃ 　　5、 高壓電纜操作的區域環境室溫為-40~+-40℃，有關的溫度濕度汛期不超過90%。 　　Operating ambient temperature of cables:-40~40℃,Relative humidity in rainy season not less than 90% 6、 通信電纜的同意微彎曲率半徑： 　　Permissible bending radius of cable: 　　額定負載端電壓0.6/1kV及下列數據線; 　　cable for rated voltage up to and including 0.6/1kV: 　　數據線外徑D<25mm者，彎折弧長不高于4D; 　　bending radius not less than 4Dfor cable diameter<25mm 　　高壓電纜外徑D≥25mm者，拉伸表面積不大于6D; 　　bending radius not less than 6Dfor cable diameter≥25mm 　　額定值工作電壓10kV、35 kV電力電纜; 　　cable for rated voltage 10 kV and 35 kV; 　　單芯拖鏈電纜：20(D+d)±5%; 　　single-core cable:20(D+d)±5%; 　　多芯拖鏈電纜：15(D+d)±5%; 　　multi-core cable:15(D+d)±5%; 　　式中：D-電力電纜的真實外徑，mm; 　　Note:D-Over all Diameter of cable 　　d-數據線導體的預期外徑， mm 　　d-Over all Diameter of conductor
