電(dian)(dian)(dian)(dian)力講解：電(dian)(dian)(dian)(dian)力安裝中(zhong)(zhong)電(dian)(dian)(dian)(dian)纜(lan)施(shi)工(gong)(gong)的(de)注意事項電(dian)(dian)(dian)(dian)力安裝是民生工(gong)(gong)程(cheng)之一，也是每個鄉村(cun)社區都不可(ke)少的(de)施(shi)工(gong)(gong)項目，然而，無論大型或(huo)小型工(gong)(gong)程(cheng)施(shi)工(gong)(gong)，其中(zhong)(zhong)電(dian)(dian)(dian)(dian)纜(lan)問題都是施(shi)工(gong)(gong)中(zhong)(zhong)核心(xin)的(de)問題，而且電(dian)(dian)(dian)(dian)纜(lan)工(gong)(gong)程(cheng)直接涉及到人身安全問題，必須引起(qi)高度重視(shi)。

那么(me)，電纜(lan)施工中有哪(na)些注意事(shi)項呢?

1、電(dian)(dian)力電(dian)(dian)纜(lan)的(de)轉彎引起的(de)機械性損傷：

由于(yu)電力(li)電纜(lan)外(wai)徑較大，運輸(shu)、敷設比較困難(nan),電力(li)電纜(lan)對轉(zhuan)彎半徑的(de)要(yao)求也(ye)比較嚴格，電纜(lan)施工(gong)過(guo)程(cheng)中，要(yao)盡可(ke)能減少電纜(lan)受(shou)到(dao)的(de)扭力(li)，在電纜(lan)轉(zhuan)彎和裕留電纜(lan)時(shi)，讓電纜(lan)處(chu)于(yu)自然(ran)彎曲(qu)，杜絕內部機(ji)械損傷(shang)現象。

2、大電流(liu)電力電纜(lan)引(yin)發(fa)的渦流(liu)

電(dian)(dian)(dian)(dian)(dian)力(li)電(dian)(dian)(dian)(dian)(dian)纜(lan)在(zai)施工中(zhong)，有(you)采(cai)(cai)(cai)用鋼支架(jia)的，有(you)采(cai)(cai)(cai)用鋼質(zhi)保護管的，有(you)采(cai)(cai)(cai)用電(dian)(dian)(dian)(dian)(dian)纜(lan)卡(ka)與架(jia)空敷設的，凡(fan)是在(zai)電(dian)(dian)(dian)(dian)(dian)力(li)電(dian)(dian)(dian)(dian)(dian)纜(lan)周Χ形成(cheng)鋼(鐵)性閉(bi)合(he)回(hui)路，均有(you)可(ke)能形成(cheng)渦流，特別是在(zai)大電(dian)(dian)(dian)(dian)(dian)流電(dian)(dian)(dian)(dian)(dian)力(li)電(dian)(dian)(dian)(dian)(dian)纜(lan)系統中(zhong)，渦流更大，所以(yi)電(dian)(dian)(dian)(dian)(dian)力(li)工程(cheng)公司(si)提醒，在(zai)電(dian)(dian)(dian)(dian)(dian)力(li)電(dian)(dian)(dian)(dian)(dian)纜(lan)施工時必(bi)須采(cai)(cai)(cai)取措(cuo)施，使電(dian)(dian)(dian)(dian)(dian)纜(lan)周Χ不能形成(cheng)鋼(鐵)性閉(bi)合(he)回(hui)路，防止電(dian)(dian)(dian)(dian)(dian)纜(lan)引起渦流現(xian)象(xiang)發生。

3、注意電(dian)力(li)纜防潮問題

據了解，中(zhong)、低(di)壓電(dian)(dian)(dian)力電(dian)(dian)(dian)纜(lan)故障大部分是電(dian)(dian)(dian)纜(lan)中(zhong)間接(jie)(jie)頭(tou)和終(zhong)端(duan)頭(tou)故障，而中(zhong)間接(jie)(jie)頭(tou)和終(zhong)端(duan)頭(tou)故障則大部分是因(yin)密封(feng)不(bu)良，潮氣侵入而造(zao)成絕(jue)緣強度下降。而中(zhong)、低(di)壓電(dian)(dian)(dian)力電(dian)(dian)(dian)纜(lan)網多(duo)采(cai)用樹枝狀供電(dian)(dian)(dian)方式，電(dian)(dian)(dian)纜(lan)終(zhong)端(duan)頭(tou)數量較(jiao)多(duo)，因(yin)此把(ba)好電(dian)(dian)(dian)纜(lan)終(zhong)端(duan)頭(tou)和中(zhong)間接(jie)(jie)頭(tou)堵?密封(feng)關是保證電(dian)(dian)(dian)纜(lan)安全可靠運行的(de)重要措施之一。
