電(dian)力講解：電(dian)力安裝中(zhong)(zhong)電(dian)纜施(shi)(shi)工的(de)注意事(shi)項電(dian)力安裝是民生工程(cheng)之一，也是每個鄉村社區都不可少的(de)施(shi)(shi)工項目(mu)，然而，無論(lun)大型(xing)或(huo)小型(xing)工程(cheng)施(shi)(shi)工，其中(zhong)(zhong)電(dian)纜問題(ti)都是施(shi)(shi)工中(zhong)(zhong)核(he)心的(de)問題(ti)，而且電(dian)纜工程(cheng)直(zhi)接涉及到人身安全問題(ti)，必須引起(qi)高(gao)度重視。

那么，電(dian)纜(lan)施工中有(you)哪些注意(yi)事項呢?

1、電力電纜的(de)(de)轉(zhuan)彎引起的(de)(de)機械(xie)性損傷：

由于電(dian)力電(dian)纜外(wai)徑較大，運輸、敷(fu)設比較困難(nan),電(dian)力電(dian)纜對轉彎(wan)半徑的(de)要(yao)求也比較嚴格，電(dian)纜施(shi)工過程中，要(yao)盡可能減少電(dian)纜受到的(de)扭力，在電(dian)纜轉彎(wan)和裕留電(dian)纜時(shi)，讓電(dian)纜處于自然彎(wan)曲，杜絕(jue)內部機械(xie)損傷現象。

2、大電(dian)流電(dian)力電(dian)纜引發的渦流

電(dian)(dian)(dian)力(li)電(dian)(dian)(dian)纜(lan)在施(shi)工中，有采(cai)用(yong)(yong)鋼支(zhi)架的(de)，有采(cai)用(yong)(yong)鋼質保護(hu)管的(de)，有采(cai)用(yong)(yong)電(dian)(dian)(dian)纜(lan)卡與(yu)架空敷設的(de)，凡(fan)是(shi)在電(dian)(dian)(dian)力(li)電(dian)(dian)(dian)纜(lan)周(zhou)(zhou)Χ形成(cheng)(cheng)鋼(鐵)性(xing)閉(bi)合回路，均有可能形成(cheng)(cheng)渦流(liu)(liu)，特別是(shi)在大電(dian)(dian)(dian)流(liu)(liu)電(dian)(dian)(dian)力(li)電(dian)(dian)(dian)纜(lan)系統中，渦流(liu)(liu)更大，所以(yi)電(dian)(dian)(dian)力(li)工程公司提醒，在電(dian)(dian)(dian)力(li)電(dian)(dian)(dian)纜(lan)施(shi)工時(shi)必(bi)須采(cai)取措(cuo)施(shi)，使電(dian)(dian)(dian)纜(lan)周(zhou)(zhou)Χ不能形成(cheng)(cheng)鋼(鐵)性(xing)閉(bi)合回路，防止電(dian)(dian)(dian)纜(lan)引起渦流(liu)(liu)現象發生。

3、注意(yi)電力(li)纜防(fang)潮問題

據了解，中(zhong)、低壓電(dian)力電(dian)纜(lan)故(gu)(gu)障大部分是(shi)電(dian)纜(lan)中(zhong)間(jian)接頭(tou)和終(zhong)端頭(tou)故(gu)(gu)障，而中(zhong)間(jian)接頭(tou)和終(zhong)端頭(tou)故(gu)(gu)障則(ze)大部分是(shi)因(yin)密封不良，潮(chao)氣侵入(ru)而造成絕緣強(qiang)度下降。而中(zhong)、低壓電(dian)力電(dian)纜(lan)網多(duo)采(cai)用樹枝狀供電(dian)方式，電(dian)纜(lan)終(zhong)端頭(tou)數量較多(duo)，因(yin)此(ci)把(ba)好電(dian)纜(lan)終(zhong)端頭(tou)和中(zhong)間(jian)接頭(tou)堵?密封關(guan)是(shi)保證電(dian)纜(lan)安(an)全可(ke)靠運行的重要措施之一。
