水泥電線桿承載力計算是根據架設電線的粗細度計算，架設電纜越粗拉力越大，使用的水泥電線桿強度要求越高。電線桿抗風能力以水泥電線桿主筋為主，主筋根數越多抗風能力越強。根據國家設計要求，根據線路選擇水泥電線桿規格，根據架設電線粗細度決定采用什么規格的水泥電桿。

水(shui)泥電線(xian)(xian)(xian)桿分(fen)為(wei)預應(ying)力(li)(li)和非(fei)預應(ying)力(li)(li)，預應(ying)力(li)(li)是采(cai)用(yong)4.8高強絲通過(guo)張拉制(zhi)作而成(cheng)，非(fei)預應(ying)力(li)(li)是采(cai)用(yong)螺紋鋼筋(jin)(jin)通過(guo)焊接成(cheng)鋼筋(jin)(jin)骨架(jia)制(zhi)作而成(cheng)。根據(ju)架(jia)設(she)(she)(she)電線(xian)(xian)(xian)選擇(ze)水(shui)泥電線(xian)(xian)(xian)桿，架(jia)設(she)(she)(she)電線(xian)(xian)(xian)較細采(cai)用(yong)預應(ying)力(li)(li)電線(xian)(xian)(xian)桿，架(jia)設(she)(she)(she)線(xian)(xian)(xian)路電線(xian)(xian)(xian)較粗采(cai)用(yong)非(fei)預應(ying)力(li)(li)水(shui)泥電線(xian)(xian)(xian)桿。
