2、據(jù)架空線路導線截面大,多種電壓,多回路共桿,造價低的特點。與傳統(tǒng)的鋼筋混凝土電桿、角鋼塔相比可以知道鋼管桿具施工維護方便、強度高,為安全運行提供了有力保證;并且也可以設計較高的鐵塔,以滿足跨越人行道、樹木的要求;易實現(xiàn)多回路,從而大大減少城市走廊的擁擠程度;不用打拉線,占地面積小,減少占用城市走廊;鋼管塔可以實現(xiàn)全鍍鋅,防銹性能大大提高同時也使鋼管桿造型美觀,與周圍環(huán)境比較協(xié)調(diào)的優(yōu)點,本著重介紹設計?220kv雙回路新型鋼管塔設計。關(guān)鍵詞:高壓輸電線,角鋼塔,電力塔,雙回路,架空線路..ABSTRACTAlongwithourcountrysustainabl
