電(dian)力講(jiang)解：電(dian)力安裝中(zhong)(zhong)電(dian)纜(lan)(lan)施工(gong)的注意事(shi)項電(dian)力安裝是民生工(gong)程之一，也是每個鄉(xiang)村(cun)社區都(dou)不可少的施工(gong)項目(mu)，然(ran)而，無論大型或小型工(gong)程施工(gong)，其中(zhong)(zhong)電(dian)纜(lan)(lan)問題(ti)(ti)都(dou)是施工(gong)中(zhong)(zhong)核心的問題(ti)(ti)，而且電(dian)纜(lan)(lan)工(gong)程直接涉及到人身安全問題(ti)(ti)，必須引起高度重視。

那么，電(dian)纜施工中有哪些注意事項呢?

1、電力電纜的轉彎引起的機械性損(sun)傷：

由于(yu)電(dian)(dian)(dian)力電(dian)(dian)(dian)纜(lan)外徑較大，運輸、敷設(she)比(bi)較困難,電(dian)(dian)(dian)力電(dian)(dian)(dian)纜(lan)對轉彎(wan)(wan)(wan)半徑的要(yao)求也比(bi)較嚴格，電(dian)(dian)(dian)纜(lan)施工過(guo)程中，要(yao)盡可(ke)能減少電(dian)(dian)(dian)纜(lan)受到的扭力，在(zai)電(dian)(dian)(dian)纜(lan)轉彎(wan)(wan)(wan)和裕留電(dian)(dian)(dian)纜(lan)時，讓電(dian)(dian)(dian)纜(lan)處(chu)于(yu)自(zi)然(ran)彎(wan)(wan)(wan)曲，杜絕內部機械損傷現象。

2、大電(dian)流電(dian)力電(dian)纜引發的渦流

電(dian)(dian)力(li)(li)電(dian)(dian)纜(lan)(lan)在施(shi)(shi)工(gong)中(zhong)，有(you)采(cai)用(yong)鋼(gang)支架的(de)，有(you)采(cai)用(yong)鋼(gang)質保(bao)護管的(de)，有(you)采(cai)用(yong)電(dian)(dian)纜(lan)(lan)卡(ka)與架空(kong)敷設的(de)，凡(fan)是(shi)在電(dian)(dian)力(li)(li)電(dian)(dian)纜(lan)(lan)周Χ形(xing)成(cheng)鋼(gang)(鐵)性閉(bi)(bi)合回路，均有(you)可能形(xing)成(cheng)渦(wo)流，特別(bie)是(shi)在大電(dian)(dian)流電(dian)(dian)力(li)(li)電(dian)(dian)纜(lan)(lan)系統(tong)中(zhong)，渦(wo)流更大，所以(yi)電(dian)(dian)力(li)(li)工(gong)程公(gong)司提醒，在電(dian)(dian)力(li)(li)電(dian)(dian)纜(lan)(lan)施(shi)(shi)工(gong)時必須采(cai)取措施(shi)(shi)，使電(dian)(dian)纜(lan)(lan)周Χ不能形(xing)成(cheng)鋼(gang)(鐵)性閉(bi)(bi)合回路，防(fang)止電(dian)(dian)纜(lan)(lan)引起(qi)渦(wo)流現(xian)象(xiang)發生。

3、注(zhu)意(yi)電(dian)力(li)纜(lan)防潮問題

據了(le)解，中(zhong)、低壓電(dian)(dian)力電(dian)(dian)纜(lan)(lan)故(gu)(gu)障(zhang)大部分是電(dian)(dian)纜(lan)(lan)中(zhong)間(jian)接(jie)頭(tou)和終(zhong)端頭(tou)故(gu)(gu)障(zhang)，而中(zhong)間(jian)接(jie)頭(tou)和終(zhong)端頭(tou)故(gu)(gu)障(zhang)則大部分是因密封不良，潮氣侵入而造成(cheng)絕(jue)緣強度下降(jiang)。而中(zhong)、低壓電(dian)(dian)力電(dian)(dian)纜(lan)(lan)網多采用樹枝狀供電(dian)(dian)方(fang)式，電(dian)(dian)纜(lan)(lan)終(zhong)端頭(tou)數量較(jiao)多，因此把好電(dian)(dian)纜(lan)(lan)終(zhong)端頭(tou)和中(zhong)間(jian)接(jie)頭(tou)堵?密封關(guan)是保證電(dian)(dian)纜(lan)(lan)安全可(ke)靠運行的(de)重要措施之一。
