        預制分支電纜
        預制分支電纜 Pre-fabricated branched cable
         
        預制分支電纜是90年代后期在國外出現的一個新產品,目前已在世界發達國家得到廣泛應用。我國由于建筑工業的迅速發展,廣泛推廣采用分支電纜日 
        益受到廣大用戶的關注和重視。分支電纜在建筑施工現場以它的配電成本低、施工周期短、裝方便、用性能可靠等優越性成為投資商、建筑商以及供電
        部門一致的首選配套產品。
        Because ofits lowe cost,short construction period,convenient assemblage and high reliability,the pre-fabricated branched cable is the preferred manufacture
        ofinvestor,building companies,and power supply bureau in nowadays.

        4.分支電纜電壓降計算branch cable voltage drop calculation
        設計干線時,  除要考慮電纜載流量外,還應考慮電壓降。當干線中間有幾處分支時,從電源到最終負載的電壓降,要根據分支電纜的電流量、干線的特性阻抗及分支的間隔按以下公式計算求出。Ed=KZ  ΣnLnIn=KZΣnLnin (V)公式中:
        Ed-電壓降(V) (相線間)K-配電常數      單相2線制:K=2    單相3線制:K=l   三相4線制:K=l
          三相5線制:K=l   in,In-區間幾的負載電流(A)    LnIn-區間幾的長度(km)    Z-纜的阻抗( Ω/km)=RcosQ+×sinQ  R-交流電阻( Ω/km)   cosQ-負載功率固數   ×-電抗(Q/km)   SinQ=

        5.分支電纜的使用安裝方法(簡介)
        5.1電纜的敷設施工方法: cable laying method
        垂直干線的預制分支電纜一般應按以下要領進行敷設; Vertical trunk pre-fabricated branched cable can be laid according to the
         following points:
        (1)將電纜盤放在放線架上(通常電纜盤放在樓下);put cable tray on the pay-offrack (cable tray is usually put downstairs)
        (2)提升電纜用的繩索通過牽引機與電纜連接;cord used to upgrade cable connect to cable by draw machine
        (3)開動牽引機將電纜提升上去; run draw machine to upgrade cable
        (4)提升用的電纜網套到達房頂時,將網套掛在事先準備好的吊鉤上;after cable net used for upgrading reaches the roof,put cable net on the advance prepared lifting hook,
        (5)對中間部位進行固定;fasten middle section ofcable
        (6)將分支線端頭與電流表或斷流器相接;connect branch terminal with amperemeter or circuit breaker
        (7)進行橫相干線或主干線板連接。connect cross direction trunk or main trunk board
         
        5.2施工注意事項:construction attention rule
        (1)事先確認運輸方法;confirm distribution method in advance
        (2)確認分支部是否能安全通過孔洞;confirm if branch can safely pass cavern
        (3)采取預防措施防止提升過程中分支部在貫通孔洞時損傷;adopt precautionary measures to avoid damage when branch passing cavern during upgrading process
        (4)提升過程中不要對分支電纜施加張力;don’t put force on branch cab]e when upgrading
        (5)使用電纜重量4倍以上強度的繩索;use cord whose strength is 4 multiple than cable weight
        (6)事先考慮避雨方法及空盤處理方法:consider rain shield method and blank panel handling method in advance
        (7)電纜提升完后,應立即將電纜固定;immediately fasten cable after lifting cable
        (8)電纜禁止直接使用鐵質夾具。forbidden to use iron chucking directly  
         
        6、訂貨須知   0rdering notice
