電(dian)力講解：電(dian)力安裝(zhuang)中(zhong)電(dian)纜施(shi)工(gong)(gong)(gong)的注意事項電(dian)力安裝(zhuang)是(shi)民生工(gong)(gong)(gong)程之(zhi)一，也是(shi)每個鄉村社區都(dou)不可(ke)少的施(shi)工(gong)(gong)(gong)項目(mu)，然而(er)，無(wu)論大(da)型(xing)或小型(xing)工(gong)(gong)(gong)程施(shi)工(gong)(gong)(gong)，其(qi)中(zhong)電(dian)纜問題都(dou)是(shi)施(shi)工(gong)(gong)(gong)中(zhong)核心的問題，而(er)且電(dian)纜工(gong)(gong)(gong)程直接(jie)涉及到人身(shen)安全問題，必須引(yin)起高度重(zhong)視。

那(nei)么(me)，電纜(lan)施工中(zhong)有哪些注意事項呢?

1、電力電纜的轉彎引(yin)起的機(ji)械性(xing)損傷：

由(you)于電(dian)(dian)(dian)力(li)電(dian)(dian)(dian)纜(lan)(lan)外徑較(jiao)大，運輸、敷設(she)比較(jiao)困難,電(dian)(dian)(dian)力(li)電(dian)(dian)(dian)纜(lan)(lan)對轉(zhuan)彎(wan)(wan)半徑的要求也(ye)比較(jiao)嚴格(ge)，電(dian)(dian)(dian)纜(lan)(lan)施工過程中，要盡(jin)可能(neng)減(jian)少電(dian)(dian)(dian)纜(lan)(lan)受到的扭(niu)力(li)，在(zai)電(dian)(dian)(dian)纜(lan)(lan)轉(zhuan)彎(wan)(wan)和裕留電(dian)(dian)(dian)纜(lan)(lan)時，讓電(dian)(dian)(dian)纜(lan)(lan)處于自然彎(wan)(wan)曲，杜絕內(nei)部機(ji)械損(sun)傷現象。

2、大電流電力(li)電纜(lan)引發的渦(wo)流

電(dian)力電(dian)纜(lan)在施(shi)工中，有采(cai)(cai)用鋼(gang)支架的(de)，有采(cai)(cai)用鋼(gang)質保(bao)護管的(de)，有采(cai)(cai)用電(dian)纜(lan)卡(ka)與架空敷(fu)設的(de)，凡(fan)是在電(dian)力電(dian)纜(lan)周(zhou)Χ形成(cheng)鋼(gang)(鐵)性閉合回路，均有可能形成(cheng)渦流(liu)，特別是在大電(dian)流(liu)電(dian)力電(dian)纜(lan)系統中，渦流(liu)更(geng)大，所以電(dian)力工程公(gong)司提醒，在電(dian)力電(dian)纜(lan)施(shi)工時必須采(cai)(cai)取措施(shi)，使電(dian)纜(lan)周(zhou)Χ不能形成(cheng)鋼(gang)(鐵)性閉合回路，防止電(dian)纜(lan)引(yin)起渦流(liu)現象發生(sheng)。

3、注意電力纜防潮問題

據了(le)解，中(zhong)(zhong)、低壓(ya)電(dian)力電(dian)纜(lan)故(gu)(gu)障(zhang)大(da)部(bu)(bu)分是電(dian)纜(lan)中(zhong)(zhong)間(jian)接(jie)頭(tou)(tou)和終(zhong)端頭(tou)(tou)故(gu)(gu)障(zhang)，而(er)中(zhong)(zhong)間(jian)接(jie)頭(tou)(tou)和終(zhong)端頭(tou)(tou)故(gu)(gu)障(zhang)則大(da)部(bu)(bu)分是因密封(feng)不良，潮(chao)氣(qi)侵(qin)入而(er)造成絕緣強(qiang)度下降。而(er)中(zhong)(zhong)、低壓(ya)電(dian)力電(dian)纜(lan)網多(duo)(duo)采(cai)用樹枝狀(zhuang)供電(dian)方式(shi)，電(dian)纜(lan)終(zhong)端頭(tou)(tou)數量較多(duo)(duo)，因此把好電(dian)纜(lan)終(zhong)端頭(tou)(tou)和中(zhong)(zhong)間(jian)接(jie)頭(tou)(tou)堵?密封(feng)關(guan)是保證電(dian)纜(lan)安全可(ke)靠運(yun)行的重要措施之一(yi)。
