電(dian)(dian)力講解：電(dian)(dian)力安裝中(zhong)(zhong)電(dian)(dian)纜施工的(de)注意(yi)事項(xiang)電(dian)(dian)力安裝是(shi)(shi)民生工程(cheng)之(zhi)一，也是(shi)(shi)每個鄉村社(she)區都不可(ke)少的(de)施工項(xiang)目，然而(er)，無(wu)論大型(xing)或小(xiao)型(xing)工程(cheng)施工，其中(zhong)(zhong)電(dian)(dian)纜問(wen)題(ti)都是(shi)(shi)施工中(zhong)(zhong)核心的(de)問(wen)題(ti)，而(er)且電(dian)(dian)纜工程(cheng)直接涉及到人(ren)身安全問(wen)題(ti)，必(bi)須引(yin)起高度重視。

那么，電纜施工中有哪些注意事(shi)項呢?

1、電(dian)力電(dian)纜的(de)(de)轉(zhuan)彎引(yin)起的(de)(de)機械性損傷：

由(you)于電(dian)(dian)(dian)(dian)力(li)(li)電(dian)(dian)(dian)(dian)纜外(wai)徑(jing)較大(da)，運(yun)輸(shu)、敷設比較困(kun)難,電(dian)(dian)(dian)(dian)力(li)(li)電(dian)(dian)(dian)(dian)纜對轉彎半徑(jing)的(de)要(yao)求也(ye)比較嚴格(ge)，電(dian)(dian)(dian)(dian)纜施工過程中，要(yao)盡可(ke)能減少電(dian)(dian)(dian)(dian)纜受(shou)到(dao)的(de)扭力(li)(li)，在電(dian)(dian)(dian)(dian)纜轉彎和裕留電(dian)(dian)(dian)(dian)纜時，讓(rang)電(dian)(dian)(dian)(dian)纜處(chu)于自然(ran)彎曲(qu)，杜絕內部機械損傷(shang)現象。

2、大(da)電流(liu)電力(li)電纜(lan)引(yin)發的(de)渦流(liu)

電(dian)(dian)(dian)力電(dian)(dian)(dian)纜(lan)在(zai)施(shi)(shi)工中，有(you)采(cai)(cai)(cai)用(yong)鋼支架的，有(you)采(cai)(cai)(cai)用(yong)鋼質保(bao)護(hu)管的，有(you)采(cai)(cai)(cai)用(yong)電(dian)(dian)(dian)纜(lan)卡與架空敷設的，凡是(shi)在(zai)電(dian)(dian)(dian)力電(dian)(dian)(dian)纜(lan)周(zhou)Χ形(xing)成鋼(鐵(tie))性閉合(he)回路，均有(you)可能(neng)(neng)形(xing)成渦流(liu)(liu)，特別是(shi)在(zai)大電(dian)(dian)(dian)流(liu)(liu)電(dian)(dian)(dian)力電(dian)(dian)(dian)纜(lan)系(xi)統中，渦流(liu)(liu)更大，所以電(dian)(dian)(dian)力工程公司提醒，在(zai)電(dian)(dian)(dian)力電(dian)(dian)(dian)纜(lan)施(shi)(shi)工時必(bi)須采(cai)(cai)(cai)取措施(shi)(shi)，使電(dian)(dian)(dian)纜(lan)周(zhou)Χ不能(neng)(neng)形(xing)成鋼(鐵(tie))性閉合(he)回路，防止電(dian)(dian)(dian)纜(lan)引(yin)起渦流(liu)(liu)現象發生。

3、注意電力纜(lan)防潮問題

據了解，中(zhong)(zhong)、低壓電(dian)力電(dian)纜(lan)(lan)故(gu)障大部(bu)分(fen)(fen)是電(dian)纜(lan)(lan)中(zhong)(zhong)間接(jie)(jie)頭(tou)和(he)終端(duan)頭(tou)故(gu)障，而(er)中(zhong)(zhong)間接(jie)(jie)頭(tou)和(he)終端(duan)頭(tou)故(gu)障則(ze)大部(bu)分(fen)(fen)是因密封不良，潮氣侵入(ru)而(er)造成絕緣(yuan)強度下降(jiang)。而(er)中(zhong)(zhong)、低壓電(dian)力電(dian)纜(lan)(lan)網多采用樹(shu)枝狀供電(dian)方式，電(dian)纜(lan)(lan)終端(duan)頭(tou)數量(liang)較多，因此把(ba)好電(dian)纜(lan)(lan)終端(duan)頭(tou)和(he)中(zhong)(zhong)間接(jie)(jie)頭(tou)堵?密封關是保證電(dian)纜(lan)(lan)安全可靠運行的重要措施之一。
