架空線詳細說明

1 架空(kong)絕(jue)(jue)緣導(dao)線(xian)(xian)(xian)的(de)(de)(de)(de)主(zhu)要(yao)(yao)特點 絕(jue)(jue)緣性(xing)能(neng)(neng)好。架空(kong)絕(jue)(jue)緣導(dao)線(xian)(xian)(xian)由于多(duo)了(le)一層絕(jue)(jue)緣層，絕(jue)(jue)緣性(xing)能(neng)(neng)比裸導(dao)線(xian)(xian)(xian)，可(ke)減少線(xian)(xian)(xian)路(lu)相(xiang)間距離，降低(di)對(dui)線(xian)(xian)(xian)路(lu)支(zhi)持件(jian)的(de)(de)(de)(de)絕(jue)(jue)緣要(yao)(yao)求(qiu)，提高同桿架設(she)線(xian)(xian)(xian)路(lu)的(de)(de)(de)(de)回路(lu)數。 防腐(fu)蝕性(xing)能(neng)(neng)好。架空(kong)絕(jue)(jue)緣導(dao)線(xian)(xian)(xian)由于外(wai)層有絕(jue)(jue)緣層，比裸導(dao)線(xian)(xian)(xian)受氧化腐(fu)蝕的(de)(de)(de)(de)程度小，抗腐(fu)蝕能(neng)(neng)力(li)較強(qiang)，可(ke)延長線(xian)(xian)(xian)路(lu)的(de)(de)(de)(de)使(shi)(shi)用(yong)(yong)(yong)壽命。 防外(wai)力(li)破壞，減少受樹木、飛飄物(wu)、金(jin)屬膜(mo)和(he)灰塵等外(wai)在因素的(de)(de)(de)(de)影響，減少相(xiang)間短路(lu)及接(jie)地(di)事故。 強(qiang)度達到(dao)要(yao)(yao)求(qiu)。絕(jue)(jue)緣導(dao)線(xian)(xian)(xian)雖(sui)然少了(le)鋼心(xin)(xin)，但堅(jian)韌，使(shi)(shi)整個導(dao)線(xian)(xian)(xian)的(de)(de)(de)(de)機械強(qiang)度達到(dao)應(ying)力(li)設(she)計(ji)的(de)(de)(de)(de)要(yao)(yao)求(qiu)。 2 架空(kong)絕(jue)(jue)緣導(dao)線(xian)(xian)(xian)的(de)(de)(de)(de)規格 線(xian)(xian)(xian)心(xin)(xin)。架空(kong)絕(jue)(jue)緣導(dao)線(xian)(xian)(xian)有鋁心(xin)(xin)和(he)銅心(xin)(xin)兩種。在配(pei)電網(wang)中(zhong)，鋁心(xin)(xin)應(ying)用(yong)(yong)(yong)比較多(duo)，主(zhu)要(yao)(yao)是鋁材比較輕，而且較便宜(yi)，對(dui)線(xian)(xian)(xian)路(lu)連(lian)接(jie)件(jian)和(he)支(zhi)持件(jian)的(de)(de)(de)(de)要(yao)(yao)求(qiu)低(di)，加上原有的(de)(de)(de)(de)配(pei)電線(xian)(xian)(xian)以鋼心(xin)(xin)鋁絞線(xian)(xian)(xian)為主(zhu)，選用(yong)(yong)(yong)鋁心(xin)(xin)線(xian)(xian)(xian)便于與原有網(wang)絡的(de)(de)(de)(de)連(lian)接(jie)。在實際使(shi)(shi)用(yong)(yong)(yong)中(zhong)也多(duo)選用(yong)(yong)(yong)鋁心(xin)(xin)線(xian)(xian)(xian)。銅心(xin)(xin)線(xian)(xian)(xian)主(zhu)要(yao)(yao)是作為變(bian)壓器及開關(guan)設(she)備的(de)(de)(de)(de)引下線(xian)(xian)(xian)。

絕(jue)(jue)(jue)緣(yuan)(yuan)(yuan)材料。架(jia)(jia)空(kong)絕(jue)(jue)(jue)緣(yuan)(yuan)(yuan)導線(xian)(xian)的絕(jue)(jue)(jue)緣(yuan)(yuan)(yuan)保(bao)護層(ceng)有厚(hou)絕(jue)(jue)(jue)緣(yuan)(yuan)(yuan)（3.4mm)和(he)薄(bo)絕(jue)(jue)(jue)緣(yuan)(yuan)(yuan)（2.5mm）兩(liang)種。厚(hou)絕(jue)(jue)(jue)緣(yuan)(yuan)(yuan)的運行時允許與樹木(mu)頻繁(fan)接觸，薄(bo)絕(jue)(jue)(jue)緣(yuan)(yuan)(yuan)的只允許與樹木(mu)短時接觸。絕(jue)(jue)(jue)緣(yuan)(yuan)(yuan)保(bao)護層(ceng)又分為交聯聚(ju)(ju)乙烯和(he)輕型聚(ju)(ju)乙烯，交聯聚(ju)(ju)乙烯的絕(jue)(jue)(jue)緣(yuan)(yuan)(yuan)性能更優良。常(chang)用(yong)的10kV架(jia)(jia)空(kong)絕(jue)(jue)(jue)緣(yuan)(yuan)(yuan)導線(xian)(xian)，達(da)州架(jia)(jia)空(kong)線(xian)(xian)纜(lan)，甘孜架(jia)(jia)空(kong)線(xian)(xian)，重(zhong)慶架(jia)(jia)空(kong)線(xian)(xian)纜(lan)，綿陽架(jia)(jia)空(kong)線(xian)(xian)纜(lan)，樂山(shan)架(jia)(jia)空(kong)線(xian)(xian)路(lu)，江北架(jia)(jia)空(kong)線(xian)(xian)，重(zhong)慶架(jia)(jia)空(kong)線(xian)(xian)纜(lan)，高低壓架(jia)(jia)空(kong)線(xian)(xian)。

3 架(jia)(jia)(jia)空絕(jue)(jue)緣(yuan)導線(xian)敷設(she)(she)方式 單根常規(gui)(gui)敷設(she)(she)方式。這(zhe)種架(jia)(jia)(jia)設(she)(she)方式就是采用(yong)目前裸導線(xian)的(de)常規(gui)(gui)水泥(ni)電桿、鐵附件及陶瓷絕(jue)(jue)緣(yuan)子配件，按裸導線(xian)架(jia)(jia)(jia)設(she)(she)方式進行架(jia)(jia)(jia)設(she)(she)，比較適合于老線(xian)路(lu)進行改造和走廊(lang)充分的(de)區域。 單根敷設(she)(she)采用(yong)的(de)絕(jue)(jue)緣(yuan)支架(jia)(jia)(jia)把導線(xian)懸(xuan)掛(gua)，這(zhe)種方式可增加(jia)架(jia)(jia)(jia)設(she)(she)的(de)回路(lu)數，節省線(xian)路(lu)走廊(lang)，降低線(xian)路(lu)單位造價。
