電力(li)講解：電力(li)安(an)裝(zhuang)中電纜施(shi)工(gong)的(de)(de)(de)注意事項電力(li)安(an)裝(zhuang)是(shi)(shi)民生工(gong)程之一，也是(shi)(shi)每個鄉村社區都不可少的(de)(de)(de)施(shi)工(gong)項目，然而，無(wu)論大型(xing)或(huo)小型(xing)工(gong)程施(shi)工(gong)，其中電纜問題都是(shi)(shi)施(shi)工(gong)中核(he)心的(de)(de)(de)問題，而且電纜工(gong)程直接涉及到人身安(an)全(quan)問題，必須引起高度重(zhong)視。

那(nei)么，電纜施工中有哪些注(zhu)意事項呢?

1、電力電纜(lan)的轉(zhuan)彎引起的機械性(xing)損(sun)傷：

由于電(dian)(dian)(dian)(dian)力電(dian)(dian)(dian)(dian)纜(lan)(lan)外徑較大，運(yun)輸(shu)、敷設比較困(kun)難,電(dian)(dian)(dian)(dian)力電(dian)(dian)(dian)(dian)纜(lan)(lan)對轉彎半徑的要(yao)求也(ye)比較嚴格，電(dian)(dian)(dian)(dian)纜(lan)(lan)施工過程中，要(yao)盡可能(neng)減少電(dian)(dian)(dian)(dian)纜(lan)(lan)受到的扭力，在電(dian)(dian)(dian)(dian)纜(lan)(lan)轉彎和裕留電(dian)(dian)(dian)(dian)纜(lan)(lan)時，讓電(dian)(dian)(dian)(dian)纜(lan)(lan)處于自然(ran)彎曲，杜絕(jue)內部機械(xie)損傷現象。

2、大電流(liu)電力電纜引(yin)發的(de)渦(wo)流(liu)

電(dian)(dian)(dian)力(li)(li)電(dian)(dian)(dian)纜(lan)在(zai)(zai)施工(gong)中，有采(cai)(cai)用(yong)鋼(gang)支架的(de)，有采(cai)(cai)用(yong)鋼(gang)質保(bao)護管(guan)的(de)，有采(cai)(cai)用(yong)電(dian)(dian)(dian)纜(lan)卡與架空敷設的(de)，凡(fan)是在(zai)(zai)電(dian)(dian)(dian)力(li)(li)電(dian)(dian)(dian)纜(lan)周Χ形(xing)(xing)成鋼(gang)(鐵)性(xing)閉合(he)回(hui)路，均有可能形(xing)(xing)成渦流(liu)(liu)，特別是在(zai)(zai)大電(dian)(dian)(dian)流(liu)(liu)電(dian)(dian)(dian)力(li)(li)電(dian)(dian)(dian)纜(lan)系統中，渦流(liu)(liu)更大，所以電(dian)(dian)(dian)力(li)(li)工(gong)程公司提醒，在(zai)(zai)電(dian)(dian)(dian)力(li)(li)電(dian)(dian)(dian)纜(lan)施工(gong)時必須采(cai)(cai)取措施，使電(dian)(dian)(dian)纜(lan)周Χ不能形(xing)(xing)成鋼(gang)(鐵)性(xing)閉合(he)回(hui)路，防(fang)止電(dian)(dian)(dian)纜(lan)引起渦流(liu)(liu)現象發(fa)生。

3、注意電力(li)纜防潮問題

據了解，中(zhong)、低壓電(dian)力電(dian)纜故障大(da)(da)部分是(shi)(shi)電(dian)纜中(zhong)間接頭(tou)(tou)(tou)和(he)終端頭(tou)(tou)(tou)故障，而中(zhong)間接頭(tou)(tou)(tou)和(he)終端頭(tou)(tou)(tou)故障則(ze)大(da)(da)部分是(shi)(shi)因密封(feng)不良，潮氣侵入而造(zao)成(cheng)絕(jue)緣強度下降。而中(zhong)、低壓電(dian)力電(dian)纜網多(duo)采用樹枝狀供電(dian)方式(shi)，電(dian)纜終端頭(tou)(tou)(tou)數量較多(duo)，因此(ci)把好電(dian)纜終端頭(tou)(tou)(tou)和(he)中(zhong)間接頭(tou)(tou)(tou)堵?密封(feng)關是(shi)(shi)保證電(dian)纜安全(quan)可靠運行的重要(yao)措施(shi)之一。
