電(dian)力講解：電(dian)力安(an)裝中電(dian)纜(lan)(lan)施(shi)工(gong)(gong)的注意事項(xiang)(xiang)電(dian)力安(an)裝是民生工(gong)(gong)程(cheng)(cheng)之一，也是每(mei)個鄉村社區都不可少的施(shi)工(gong)(gong)項(xiang)(xiang)目，然而，無論大型或小型工(gong)(gong)程(cheng)(cheng)施(shi)工(gong)(gong)，其中電(dian)纜(lan)(lan)問題(ti)(ti)都是施(shi)工(gong)(gong)中核心的問題(ti)(ti)，而且電(dian)纜(lan)(lan)工(gong)(gong)程(cheng)(cheng)直接(jie)涉及到(dao)人身安(an)全問題(ti)(ti)，必須(xu)引起高(gao)度(du)重視(shi)。

那么，電纜(lan)施工中有哪些(xie)注(zhu)意事項呢?

1、電力電纜(lan)的轉彎引起的機械性損傷：

由于電力(li)電纜外(wai)徑(jing)(jing)較(jiao)大，運(yun)輸、敷(fu)設比(bi)較(jiao)困難,電力(li)電纜對轉彎半徑(jing)(jing)的(de)(de)要求也(ye)比(bi)較(jiao)嚴格，電纜施工過(guo)程中，要盡可能減(jian)少電纜受到的(de)(de)扭力(li)，在電纜轉彎和(he)裕留電纜時，讓電纜處于自然(ran)彎曲，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)(dian)力(li)電(dian)(dian)(dian)纜(lan)在(zai)施(shi)工(gong)中，有采(cai)用鋼(gang)支架的，有采(cai)用鋼(gang)質保護管(guan)的，有采(cai)用電(dian)(dian)(dian)纜(lan)卡與架空敷(fu)設的，凡是在(zai)電(dian)(dian)(dian)力(li)電(dian)(dian)(dian)纜(lan)周Χ形(xing)(xing)成鋼(gang)(鐵(tie))性閉合回路，均(jun)有可能形(xing)(xing)成渦流，特別是在(zai)大電(dian)(dian)(dian)流電(dian)(dian)(dian)力(li)電(dian)(dian)(dian)纜(lan)系(xi)統中，渦流更大，所以電(dian)(dian)(dian)力(li)工(gong)程公司(si)提醒，在(zai)電(dian)(dian)(dian)力(li)電(dian)(dian)(dian)纜(lan)施(shi)工(gong)時必(bi)須采(cai)取措施(shi)，使電(dian)(dian)(dian)纜(lan)周Χ不(bu)能形(xing)(xing)成鋼(gang)(鐵(tie))性閉合回路，防止電(dian)(dian)(dian)纜(lan)引起渦流現象發(fa)生。

3、注(zhu)意(yi)電(dian)力纜(lan)防潮問題

據了(le)解(jie)，中、低壓(ya)電(dian)(dian)(dian)力電(dian)(dian)(dian)纜(lan)(lan)(lan)故障(zhang)(zhang)大部(bu)分是電(dian)(dian)(dian)纜(lan)(lan)(lan)中間(jian)接頭(tou)(tou)(tou)(tou)和(he)終端(duan)頭(tou)(tou)(tou)(tou)故障(zhang)(zhang)，而(er)中間(jian)接頭(tou)(tou)(tou)(tou)和(he)終端(duan)頭(tou)(tou)(tou)(tou)故障(zhang)(zhang)則大部(bu)分是因密封不良，潮(chao)氣侵入(ru)而(er)造成絕緣強度下降(jiang)。而(er)中、低壓(ya)電(dian)(dian)(dian)力電(dian)(dian)(dian)纜(lan)(lan)(lan)網多采用樹(shu)枝狀供電(dian)(dian)(dian)方式，電(dian)(dian)(dian)纜(lan)(lan)(lan)終端(duan)頭(tou)(tou)(tou)(tou)數量較多，因此把(ba)好電(dian)(dian)(dian)纜(lan)(lan)(lan)終端(duan)頭(tou)(tou)(tou)(tou)和(he)中間(jian)接頭(tou)(tou)(tou)(tou)堵?密封關是保證電(dian)(dian)(dian)纜(lan)(lan)(lan)安(an)全可(ke)靠運行的(de)重要措施(shi)之一。
