電(dian)(dian)力講(jiang)解：電(dian)(dian)力安(an)裝中(zhong)電(dian)(dian)纜(lan)施(shi)工的注意(yi)事項電(dian)(dian)力安(an)裝是(shi)民生工程(cheng)之一，也是(shi)每個鄉村社區都不可少的施(shi)工項目，然而(er)，無論大型或小(xiao)型工程(cheng)施(shi)工，其中(zhong)電(dian)(dian)纜(lan)問(wen)題(ti)(ti)都是(shi)施(shi)工中(zhong)核心的問(wen)題(ti)(ti)，而(er)且電(dian)(dian)纜(lan)工程(cheng)直接涉(she)及到人身安(an)全問(wen)題(ti)(ti)，必須引起高度重視。

那么，電纜施工(gong)中有哪(na)些注意事(shi)項呢?

1、電力電纜的轉彎引起(qi)的機械(xie)性損(sun)傷：

由于電(dian)(dian)力(li)電(dian)(dian)纜(lan)外徑(jing)(jing)較(jiao)大，運(yun)輸、敷設比較(jiao)困難,電(dian)(dian)力(li)電(dian)(dian)纜(lan)對轉彎(wan)半徑(jing)(jing)的要求(qiu)也比較(jiao)嚴格，電(dian)(dian)纜(lan)施工(gong)過程中，要盡可能減少電(dian)(dian)纜(lan)受到的扭力(li)，在(zai)電(dian)(dian)纜(lan)轉彎(wan)和裕(yu)留電(dian)(dian)纜(lan)時(shi)，讓電(dian)(dian)纜(lan)處于自然彎(wan)曲，杜(du)絕內部(bu)機械損傷(shang)現(xian)象。

2、大電(dian)流電(dian)力電(dian)纜引(yin)發的渦流

電力(li)(li)電纜(lan)在(zai)施(shi)工中，有(you)采(cai)用鋼支(zhi)架的(de)，有(you)采(cai)用鋼質保護管的(de)，有(you)采(cai)用電纜(lan)卡(ka)與架空敷(fu)設的(de)，凡是在(zai)電力(li)(li)電纜(lan)周Χ形成鋼(鐵)性閉合回路，均有(you)可能(neng)形成渦流，特(te)別是在(zai)大(da)電流電力(li)(li)電纜(lan)系統中，渦流更大(da)，所以(yi)電力(li)(li)工程公司提醒，在(zai)電力(li)(li)電纜(lan)施(shi)工時必須采(cai)取措施(shi)，使電纜(lan)周Χ不能(neng)形成鋼(鐵)性閉合回路，防(fang)止(zhi)電纜(lan)引(yin)起渦流現象發生。

3、注意電力(li)纜(lan)防(fang)潮問題

據了解，中、低壓電(dian)(dian)(dian)(dian)力電(dian)(dian)(dian)(dian)纜(lan)故(gu)障(zhang)大部分是(shi)(shi)電(dian)(dian)(dian)(dian)纜(lan)中間(jian)接(jie)頭(tou)和終(zhong)端(duan)(duan)(duan)頭(tou)故(gu)障(zhang)，而中間(jian)接(jie)頭(tou)和終(zhong)端(duan)(duan)(duan)頭(tou)故(gu)障(zhang)則大部分是(shi)(shi)因(yin)密封不(bu)良，潮氣(qi)侵入而造成絕緣強度下降。而中、低壓電(dian)(dian)(dian)(dian)力電(dian)(dian)(dian)(dian)纜(lan)網多采用(yong)樹枝(zhi)狀(zhuang)供電(dian)(dian)(dian)(dian)方式，電(dian)(dian)(dian)(dian)纜(lan)終(zhong)端(duan)(duan)(duan)頭(tou)數量較多，因(yin)此把好(hao)電(dian)(dian)(dian)(dian)纜(lan)終(zhong)端(duan)(duan)(duan)頭(tou)和中間(jian)接(jie)頭(tou)堵?密封關是(shi)(shi)保證電(dian)(dian)(dian)(dian)纜(lan)安全可靠運行的(de)重要(yao)措施之一。
