電力講解(jie)：電力安(an)裝中電纜施(shi)(shi)(shi)工(gong)(gong)的注意(yi)事項電力安(an)裝是民生工(gong)(gong)程之(zhi)一，也(ye)是每(mei)個鄉村社區都不可少的施(shi)(shi)(shi)工(gong)(gong)項目，然而，無論大型或小型工(gong)(gong)程施(shi)(shi)(shi)工(gong)(gong)，其中電纜問題都是施(shi)(shi)(shi)工(gong)(gong)中核心的問題，而且電纜工(gong)(gong)程直接(jie)涉及到人身安(an)全(quan)問題，必須引起高度重視。

那么，電纜施工中有哪些注意事項(xiang)呢?

1、電(dian)力電(dian)纜的轉彎引起的機械性(xing)損傷：

由于電(dian)(dian)(dian)(dian)力(li)電(dian)(dian)(dian)(dian)纜(lan)外徑較(jiao)大，運輸(shu)、敷設比(bi)較(jiao)困難,電(dian)(dian)(dian)(dian)力(li)電(dian)(dian)(dian)(dian)纜(lan)對轉(zhuan)彎半徑的要求也(ye)比(bi)較(jiao)嚴格，電(dian)(dian)(dian)(dian)纜(lan)施工(gong)過程(cheng)中，要盡可能減少電(dian)(dian)(dian)(dian)纜(lan)受到的扭力(li)，在電(dian)(dian)(dian)(dian)纜(lan)轉(zhuan)彎和裕留(liu)電(dian)(dian)(dian)(dian)纜(lan)時(shi)，讓(rang)電(dian)(dian)(dian)(dian)纜(lan)處(chu)于自然彎曲，杜絕內部機械損傷(shang)現象。

2、大電(dian)流(liu)電(dian)力電(dian)纜引發的(de)渦流(liu)

電(dian)力(li)(li)電(dian)纜(lan)在施(shi)(shi)工(gong)(gong)(gong)中，有(you)(you)(you)采(cai)用鋼(gang)支架的，有(you)(you)(you)采(cai)用鋼(gang)質保護管(guan)的，有(you)(you)(you)采(cai)用電(dian)纜(lan)卡與架空敷(fu)設的，凡是(shi)在電(dian)力(li)(li)電(dian)纜(lan)周(zhou)Χ形(xing)成鋼(gang)(鐵(tie))性閉合回(hui)路，均有(you)(you)(you)可(ke)能形(xing)成渦(wo)流，特別是(shi)在大電(dian)流電(dian)力(li)(li)電(dian)纜(lan)系(xi)統中，渦(wo)流更大，所以電(dian)力(li)(li)工(gong)(gong)(gong)程公司(si)提醒(xing)，在電(dian)力(li)(li)電(dian)纜(lan)施(shi)(shi)工(gong)(gong)(gong)時必(bi)須采(cai)取措施(shi)(shi)，使電(dian)纜(lan)周(zhou)Χ不能形(xing)成鋼(gang)(鐵(tie))性閉合回(hui)路，防止電(dian)纜(lan)引起渦(wo)流現象發生。

3、注意電力(li)纜(lan)防潮(chao)問題

據了解，中(zhong)(zhong)、低壓電(dian)(dian)(dian)力(li)(li)電(dian)(dian)(dian)纜故障(zhang)大部分(fen)是電(dian)(dian)(dian)纜中(zhong)(zhong)間接頭和(he)終端頭故障(zhang)，而(er)(er)中(zhong)(zhong)間接頭和(he)終端頭故障(zhang)則大部分(fen)是因密封不良，潮氣侵入而(er)(er)造(zao)成絕緣強度下降(jiang)。而(er)(er)中(zhong)(zhong)、低壓電(dian)(dian)(dian)力(li)(li)電(dian)(dian)(dian)纜網多采用(yong)樹(shu)枝狀供電(dian)(dian)(dian)方式，電(dian)(dian)(dian)纜終端頭數量較多，因此(ci)把好電(dian)(dian)(dian)纜終端頭和(he)中(zhong)(zhong)間接頭堵(du)?密封關是保證電(dian)(dian)(dian)纜安全可靠運行的重要措施之一(yi)。
