產品的簡潔Introduction 　　該類產品是在緊壓的銅、鋁導體擠制內屏弊層和耐候化學交聯聚乙稀或耐候型灰黑色高體積密度聚乙稀接地性層和外屏弊層而提煉出(1kV鋪設接地性高壓電纜未內外線 屏弊層)，構造簡潔、安全管理衛生可靠性，同樣又都具有達標率率的自動化電學穩定性指標和電穩定性指標，耐電痕、耐沿面蓄電池放電、耐臭氧層穩定性指標達標率率，與祼線纜較之，敷設 齒隙小，節電方式走郎，方式交流電壓降減短，更是是減小供氣重大事故發生的，為了確保人生路安全管理衛生。 　　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. 　　成品標準的Standard 　　本產品按GB12527-90、GB14049-93實施研發。 　　The products shall comply with the standards GB12527-90 and GB14049-93. 　　符合范圍內Applications 　　本食品適宜于高管建造群、旅游酒店發展區及植物多叢中北部的1kV、10kV、35kV空架輸配電盤錢路。 　　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. 　　用到形態Operating characteristics 　　1、 電力電纜電機額定功率輸出功率U0/U以分成三大：a.0.6/1kV b. 10kV c.. 35kV。 　　The rated voltage of cable has three classes: 　　2、 低壓電纜導體的長時準許操作溫差： 　　Continuous permissible operating temperature: 　　聚氯乙稀隔絕為70℃; 　　PVC Insulation:70℃ 　　聚丁二烯絕緣層為70℃; 　　PE Insulation: 70℃ 　　高高度密集聚乙稀為75℃; 　　HDPE Insulation: 75℃; 　　熱塑聚丁二烯接地為90℃; 　　XLPE Insulation: 90℃; 　　3、 串電時(長連續時長不多于5秒)，電纜電線的高溫度： 　　Max.Temperature of cable under short-circuit(5sec.Max.Duration) 　　聚氯乙稀絕緣電阻為160℃; 　　PVC Insulation: 160℃; 　　聚氯乙烯絕緣帶為130℃; 　　PE Insulation: 130℃ 　　高體積聚丁二烯為150℃; 　　HDPE Insulation: 150℃; 　　交連聚乙稀隔絕為250℃; 　　XLPE Insulation: 250℃; 　　4、 高壓電纜的敷設體溫應不底于-20℃。 　　Laying temperature of cable not less than -20℃ 　　5、 電線的使用的區域熱度為-40~+-40℃，關于內部含水率多雨不需小于90%。 　　Operating ambient temperature of cables:-40~40℃,Relative humidity in rainy season not less than 90% 6、 纜線的不得耐折回轉半徑： 　　Permissible bending radius of cable: 　　額定負載電阻0.6/1kV及下面電覽; 　　cable for rated voltage up to and including 0.6/1kV: 　　電纜電線外徑D<25mm者，彎曲成回轉半徑不小于等于4D; 　　bending radius not less than 4Dfor cable diameter<25mm 　　高壓電纜外徑D≥25mm者，彎度傾斜角不大于6D; 　　bending radius not less than 6Dfor cable diameter≥25mm 　　電機額定功率直流電壓10kV、35 kV拖鏈電纜; 　　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%; 　　多芯電覽：15(D+d)±5%; 　　multi-core cable:15(D+d)±5%; 　　式中：D-拖鏈電纜的實際上的外徑，mm; 　　Note:D-Over all Diameter of cable 　　d-低壓電纜導體的預期外徑， mm 　　d-Over all Diameter of conductor
