電(dian)(dian)力講解：電(dian)(dian)力安(an)裝(zhuang)中(zhong)(zhong)電(dian)(dian)纜施(shi)工(gong)的注意事項電(dian)(dian)力安(an)裝(zhuang)是(shi)民生工(gong)程之一(yi)，也是(shi)每個鄉村社區都不可少的施(shi)工(gong)項目，然而，無論大型或小型工(gong)程施(shi)工(gong)，其中(zhong)(zhong)電(dian)(dian)纜問(wen)題(ti)(ti)都是(shi)施(shi)工(gong)中(zhong)(zhong)核心(xin)的問(wen)題(ti)(ti)，而且電(dian)(dian)纜工(gong)程直接涉及(ji)到人身安(an)全問(wen)題(ti)(ti)，必須引起高(gao)度重視。

那么，電纜施工中有哪些(xie)注意事項(xiang)呢?

1、電(dian)力電(dian)纜的(de)轉彎引起的(de)機械性損(sun)傷：

由(you)于電(dian)(dian)(dian)力電(dian)(dian)(dian)纜(lan)外徑較(jiao)大，運輸、敷設比(bi)(bi)較(jiao)困難,電(dian)(dian)(dian)力電(dian)(dian)(dian)纜(lan)對轉(zhuan)(zhuan)彎(wan)半徑的要求也(ye)比(bi)(bi)較(jiao)嚴格，電(dian)(dian)(dian)纜(lan)施(shi)工(gong)過程中，要盡(jin)可能減少電(dian)(dian)(dian)纜(lan)受到(dao)的扭力，在電(dian)(dian)(dian)纜(lan)轉(zhuan)(zhuan)彎(wan)和裕留(liu)電(dian)(dian)(dian)纜(lan)時(shi)，讓電(dian)(dian)(dian)纜(lan)處(chu)于自然彎(wan)曲，杜絕內部機(ji)械損(sun)傷(shang)現(xian)象。

2、大電流電力電纜引發的渦流

電(dian)(dian)力電(dian)(dian)纜(lan)(lan)在(zai)施(shi)工(gong)(gong)中，有采(cai)(cai)用鋼(gang)(gang)支架的，有采(cai)(cai)用鋼(gang)(gang)質保(bao)護管的，有采(cai)(cai)用電(dian)(dian)纜(lan)(lan)卡與架空敷(fu)設的，凡是在(zai)電(dian)(dian)力電(dian)(dian)纜(lan)(lan)周(zhou)Χ形成鋼(gang)(gang)(鐵(tie))性閉合(he)回路，均有可能形成渦(wo)流(liu)，特別是在(zai)大電(dian)(dian)流(liu)電(dian)(dian)力電(dian)(dian)纜(lan)(lan)系統中，渦(wo)流(liu)更大，所以電(dian)(dian)力工(gong)(gong)程公司提醒，在(zai)電(dian)(dian)力電(dian)(dian)纜(lan)(lan)施(shi)工(gong)(gong)時必(bi)須采(cai)(cai)取措施(shi)，使電(dian)(dian)纜(lan)(lan)周(zhou)Χ不能形成鋼(gang)(gang)(鐵(tie))性閉合(he)回路，防止電(dian)(dian)纜(lan)(lan)引起(qi)渦(wo)流(liu)現象發生(sheng)。

3、注意(yi)電(dian)力纜防潮問題

據了解，中、低壓(ya)電(dian)(dian)力電(dian)(dian)纜(lan)故障(zhang)大(da)部(bu)分(fen)(fen)是電(dian)(dian)纜(lan)中間(jian)接頭(tou)(tou)和終(zhong)端頭(tou)(tou)故障(zhang)，而中間(jian)接頭(tou)(tou)和終(zhong)端頭(tou)(tou)故障(zhang)則大(da)部(bu)分(fen)(fen)是因(yin)(yin)密封不良，潮氣侵(qin)入而造(zao)成絕緣(yuan)強度下降。而中、低壓(ya)電(dian)(dian)力電(dian)(dian)纜(lan)網多(duo)采用樹枝狀供(gong)電(dian)(dian)方式，電(dian)(dian)纜(lan)終(zhong)端頭(tou)(tou)數量較多(duo)，因(yin)(yin)此把好電(dian)(dian)纜(lan)終(zhong)端頭(tou)(tou)和中間(jian)接頭(tou)(tou)堵?密封關是保證電(dian)(dian)纜(lan)安全(quan)可(ke)靠(kao)運行的重要措施之一。
