電(dian)(dian)力(li)講解：電(dian)(dian)力(li)安裝中(zhong)(zhong)電(dian)(dian)纜(lan)施(shi)工(gong)(gong)(gong)的注意事項(xiang)電(dian)(dian)力(li)安裝是(shi)民生工(gong)(gong)(gong)程之(zhi)一，也是(shi)每個鄉村(cun)社區(qu)都(dou)不可少(shao)的施(shi)工(gong)(gong)(gong)項(xiang)目，然而，無論大型或小型工(gong)(gong)(gong)程施(shi)工(gong)(gong)(gong)，其中(zhong)(zhong)電(dian)(dian)纜(lan)問(wen)題都(dou)是(shi)施(shi)工(gong)(gong)(gong)中(zhong)(zhong)核心的問(wen)題，而且電(dian)(dian)纜(lan)工(gong)(gong)(gong)程直接涉及到人身安全問(wen)題，必須(xu)引起高度重(zhong)視。

那么(me)，電纜(lan)施工中有(you)哪些注(zhu)意事項呢(ni)?

1、電力電纜的轉彎引起的機械性損傷(shang)：

由于電(dian)(dian)力(li)電(dian)(dian)纜(lan)(lan)(lan)外徑(jing)較大，運(yun)輸、敷設比較困難,電(dian)(dian)力(li)電(dian)(dian)纜(lan)(lan)(lan)對(dui)轉彎半徑(jing)的要求也比較嚴格，電(dian)(dian)纜(lan)(lan)(lan)施工過程(cheng)中(zhong)，要盡(jin)可能減少(shao)電(dian)(dian)纜(lan)(lan)(lan)受到的扭力(li)，在電(dian)(dian)纜(lan)(lan)(lan)轉彎和裕留電(dian)(dian)纜(lan)(lan)(lan)時，讓電(dian)(dian)纜(lan)(lan)(lan)處(chu)于自(zi)然彎曲，杜(du)絕內(nei)部(bu)機(ji)械(xie)損傷(shang)現象。

2、大(da)電流電力電纜引發的渦流

電(dian)(dian)(dian)力(li)電(dian)(dian)(dian)纜(lan)(lan)在施(shi)工中，有(you)采(cai)用鋼支架的，有(you)采(cai)用鋼質保護管的，有(you)采(cai)用電(dian)(dian)(dian)纜(lan)(lan)卡與架空敷設的，凡是在電(dian)(dian)(dian)力(li)電(dian)(dian)(dian)纜(lan)(lan)周(zhou)Χ形(xing)成(cheng)鋼(鐵)性(xing)閉(bi)合回路(lu)，均有(you)可能形(xing)成(cheng)渦流，特別(bie)是在大(da)電(dian)(dian)(dian)流電(dian)(dian)(dian)力(li)電(dian)(dian)(dian)纜(lan)(lan)系統中，渦流更大(da)，所以電(dian)(dian)(dian)力(li)工程公司提(ti)醒，在電(dian)(dian)(dian)力(li)電(dian)(dian)(dian)纜(lan)(lan)施(shi)工時必(bi)須采(cai)取措施(shi)，使電(dian)(dian)(dian)纜(lan)(lan)周(zhou)Χ不能形(xing)成(cheng)鋼(鐵)性(xing)閉(bi)合回路(lu)，防(fang)止電(dian)(dian)(dian)纜(lan)(lan)引起渦流現(xian)象(xiang)發生(sheng)。

3、注意電(dian)力(li)纜防潮問題

據了解，中(zhong)、低壓(ya)電(dian)力(li)電(dian)纜(lan)故(gu)(gu)障(zhang)大部分(fen)是電(dian)纜(lan)中(zhong)間(jian)接(jie)頭和(he)終端(duan)頭故(gu)(gu)障(zhang)，而中(zhong)間(jian)接(jie)頭和(he)終端(duan)頭故(gu)(gu)障(zhang)則大部分(fen)是因密封不良(liang)，潮氣侵入而造成絕緣強(qiang)度下(xia)降。而中(zhong)、低壓(ya)電(dian)力(li)電(dian)纜(lan)網(wang)多采用樹枝狀(zhuang)供電(dian)方式，電(dian)纜(lan)終端(duan)頭數(shu)量較多，因此把(ba)好(hao)電(dian)纜(lan)終端(duan)頭和(he)中(zhong)間(jian)接(jie)頭堵?密封關是保(bao)證電(dian)纜(lan)安全可靠運(yun)行(xing)的(de)重要(yao)措施之一。
