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。E_d=KZ  Σ_nL_nI_n=KZΣ_nL_ni_n (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   i_n,I_n-區間幾的負載電流(A)    L_nI_n-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
