                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.

                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=
                When desingning main trunk,cable carrying Capacity and voltage drop should be considered When several branches appear in the middle of main trunk,voltage drop between power source and ending load should calculated by the following formula according to branch cable current,trunk characteristic impedance and branch interval  In the formula:Ed-voltage drop K:distribution constant  Single-phase two-wire:K=2   Single-phase tri-wire:K=l  Tri-phase four-wire:K=l  Tri-phase five-wire:K-l  Interval n load current Interval n length Z-cable impedance   R-AC resistance  ×-reactance

                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
