電力(li)講解(jie)：電力(li)安裝(zhuang)中(zhong)電纜(lan)(lan)施工的(de)(de)注意事項(xiang)電力(li)安裝(zhuang)是(shi)民生(sheng)工程之一(yi)，也是(shi)每個鄉村社區都(dou)不可少的(de)(de)施工項(xiang)目，然(ran)而，無論大型或小型工程施工，其中(zhong)電纜(lan)(lan)問題都(dou)是(shi)施工中(zhong)核心的(de)(de)問題，而且電纜(lan)(lan)工程直接涉及到人(ren)身安全問題，必(bi)須引起(qi)高度(du)重視。

那么，電纜施工中(zhong)有哪些注意事項呢(ni)?

1、電(dian)力電(dian)纜的轉彎引起(qi)的機械性損傷：

由于(yu)電(dian)(dian)力電(dian)(dian)纜(lan)外(wai)徑(jing)較(jiao)大，運(yun)輸(shu)、敷(fu)設比較(jiao)困(kun)難,電(dian)(dian)力電(dian)(dian)纜(lan)對轉彎(wan)半(ban)徑(jing)的要(yao)求也比較(jiao)嚴格(ge)，電(dian)(dian)纜(lan)施工過程(cheng)中，要(yao)盡可能(neng)減少電(dian)(dian)纜(lan)受到的扭力，在電(dian)(dian)纜(lan)轉彎(wan)和裕留(liu)電(dian)(dian)纜(lan)時，讓電(dian)(dian)纜(lan)處于(yu)自然彎(wan)曲，杜(du)絕內部機械損(sun)傷現象(xiang)。

2、大電流電力電纜引發的渦流

電(dian)(dian)(dian)力(li)(li)電(dian)(dian)(dian)纜在施工(gong)中(zhong)，有采(cai)(cai)用(yong)鋼支架的(de)，有采(cai)(cai)用(yong)鋼質保護管的(de)，有采(cai)(cai)用(yong)電(dian)(dian)(dian)纜卡與架空(kong)敷設(she)的(de)，凡是(shi)在電(dian)(dian)(dian)力(li)(li)電(dian)(dian)(dian)纜周(zhou)Χ形成(cheng)鋼(鐵(tie)(tie))性(xing)閉(bi)合回路，均有可能形成(cheng)渦(wo)流(liu)，特別是(shi)在大(da)電(dian)(dian)(dian)流(liu)電(dian)(dian)(dian)力(li)(li)電(dian)(dian)(dian)纜系統中(zhong)，渦(wo)流(liu)更大(da)，所以電(dian)(dian)(dian)力(li)(li)工(gong)程公司提醒，在電(dian)(dian)(dian)力(li)(li)電(dian)(dian)(dian)纜施工(gong)時必須采(cai)(cai)取(qu)措施，使電(dian)(dian)(dian)纜周(zhou)Χ不能形成(cheng)鋼(鐵(tie)(tie))性(xing)閉(bi)合回路，防止電(dian)(dian)(dian)纜引起渦(wo)流(liu)現象(xiang)發生。

3、注意電力(li)纜(lan)防潮(chao)問題(ti)

據了解，中(zhong)(zhong)、低壓(ya)電(dian)力(li)電(dian)纜(lan)故(gu)障(zhang)大部分(fen)是(shi)(shi)電(dian)纜(lan)中(zhong)(zhong)間接(jie)頭(tou)(tou)(tou)和(he)終(zhong)端(duan)頭(tou)(tou)(tou)故(gu)障(zhang)，而(er)(er)中(zhong)(zhong)間接(jie)頭(tou)(tou)(tou)和(he)終(zhong)端(duan)頭(tou)(tou)(tou)故(gu)障(zhang)則大部分(fen)是(shi)(shi)因密封不良，潮氣侵入(ru)而(er)(er)造(zao)成絕緣強度下(xia)降。而(er)(er)中(zhong)(zhong)、低壓(ya)電(dian)力(li)電(dian)纜(lan)網多采(cai)用(yong)樹(shu)枝狀供(gong)電(dian)方式，電(dian)纜(lan)終(zhong)端(duan)頭(tou)(tou)(tou)數(shu)量較(jiao)多，因此(ci)把好電(dian)纜(lan)終(zhong)端(duan)頭(tou)(tou)(tou)和(he)中(zhong)(zhong)間接(jie)頭(tou)(tou)(tou)堵?密封關是(shi)(shi)保證(zheng)電(dian)纜(lan)安全可靠運行的重要措施之一。
