電(dian)(dian)力講(jiang)解：電(dian)(dian)力安裝中電(dian)(dian)纜施(shi)工(gong)(gong)的(de)(de)注意事項電(dian)(dian)力安裝是民生工(gong)(gong)程(cheng)之一，也是每個鄉村(cun)社區都不可少的(de)(de)施(shi)工(gong)(gong)項目，然而，無論大型或小型工(gong)(gong)程(cheng)施(shi)工(gong)(gong)，其中電(dian)(dian)纜問(wen)題都是施(shi)工(gong)(gong)中核(he)心的(de)(de)問(wen)題，而且電(dian)(dian)纜工(gong)(gong)程(cheng)直接涉(she)及到人身安全(quan)問(wen)題，必須引(yin)起高度(du)重視。

那么，電纜施工中有哪些注意(yi)事項呢?

1、電力電纜(lan)的轉彎引(yin)起的機械性損傷：

由于電(dian)(dian)力(li)電(dian)(dian)纜(lan)外徑較大，運輸、敷設比(bi)較困難(nan),電(dian)(dian)力(li)電(dian)(dian)纜(lan)對(dui)轉彎半徑的要(yao)求(qiu)也比(bi)較嚴格，電(dian)(dian)纜(lan)施(shi)工過程中(zhong)，要(yao)盡可能減少電(dian)(dian)纜(lan)受到的扭力(li)，在電(dian)(dian)纜(lan)轉彎和(he)裕留電(dian)(dian)纜(lan)時，讓(rang)電(dian)(dian)纜(lan)處于自然彎曲，杜(du)絕內部機械(xie)損傷現象。

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

電(dian)(dian)(dian)(dian)力(li)電(dian)(dian)(dian)(dian)纜(lan)在施工(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(bao)護管(guan)的，有(you)(you)(you)采(cai)用電(dian)(dian)(dian)(dian)纜(lan)卡與架空敷設的，凡(fan)是在電(dian)(dian)(dian)(dian)力(li)電(dian)(dian)(dian)(dian)纜(lan)周Χ形(xing)成(cheng)鋼(gang)(鐵(tie)(tie))性閉合回(hui)路，均有(you)(you)(you)可(ke)能形(xing)成(cheng)渦(wo)流，特別是在大電(dian)(dian)(dian)(dian)流電(dian)(dian)(dian)(dian)力(li)電(dian)(dian)(dian)(dian)纜(lan)系(xi)統中，渦(wo)流更大，所以電(dian)(dian)(dian)(dian)力(li)工(gong)(gong)程(cheng)公司提醒，在電(dian)(dian)(dian)(dian)力(li)電(dian)(dian)(dian)(dian)纜(lan)施工(gong)(gong)時(shi)必須采(cai)取措施，使電(dian)(dian)(dian)(dian)纜(lan)周Χ不能形(xing)成(cheng)鋼(gang)(鐵(tie)(tie))性閉合回(hui)路，防(fang)止電(dian)(dian)(dian)(dian)纜(lan)引(yin)起渦(wo)流現象發(fa)生。

3、注意電力纜防潮(chao)問題

據了解(jie)，中(zhong)(zhong)(zhong)、低(di)壓電(dian)(dian)(dian)(dian)力電(dian)(dian)(dian)(dian)纜故障(zhang)大部分是電(dian)(dian)(dian)(dian)纜中(zhong)(zhong)(zhong)間接(jie)頭和終端(duan)頭故障(zhang)，而中(zhong)(zhong)(zhong)間接(jie)頭和終端(duan)頭故障(zhang)則大部分是因(yin)密封不良，潮(chao)氣侵入而造(zao)成絕(jue)緣強度下降(jiang)。而中(zhong)(zhong)(zhong)、低(di)壓電(dian)(dian)(dian)(dian)力電(dian)(dian)(dian)(dian)纜網多采(cai)用(yong)樹枝狀供電(dian)(dian)(dian)(dian)方(fang)式，電(dian)(dian)(dian)(dian)纜終端(duan)頭數量較多，因(yin)此把(ba)好電(dian)(dian)(dian)(dian)纜終端(duan)頭和中(zhong)(zhong)(zhong)間接(jie)頭堵?密封關是保證電(dian)(dian)(dian)(dian)纜安(an)全可靠運(yun)行的重要(yao)措施之一。
