電(dian)力講解(jie)：電(dian)力安(an)裝(zhuang)中電(dian)纜(lan)(lan)施工(gong)的注(zhu)意事項電(dian)力安(an)裝(zhuang)是(shi)民(min)生工(gong)程之一(yi)，也是(shi)每個鄉村(cun)社區都(dou)不可(ke)少的施工(gong)項目，然而(er)，無論大型或小型工(gong)程施工(gong)，其(qi)中電(dian)纜(lan)(lan)問(wen)題都(dou)是(shi)施工(gong)中核心(xin)的問(wen)題，而(er)且電(dian)纜(lan)(lan)工(gong)程直接涉(she)及(ji)到人身安(an)全問(wen)題，必須引(yin)起(qi)高度重視。

那么，電纜施工(gong)中有(you)哪些注意事項呢?

1、電(dian)力(li)電(dian)纜的(de)轉(zhuan)彎(wan)引起的(de)機械性(xing)損傷：

由于電(dian)(dian)力(li)電(dian)(dian)纜(lan)(lan)(lan)外徑較大，運輸、敷設比較困難,電(dian)(dian)力(li)電(dian)(dian)纜(lan)(lan)(lan)對轉彎半(ban)徑的要(yao)(yao)求也比較嚴格，電(dian)(dian)纜(lan)(lan)(lan)施工過程中，要(yao)(yao)盡(jin)可能減少電(dian)(dian)纜(lan)(lan)(lan)受(shou)到的扭力(li)，在電(dian)(dian)纜(lan)(lan)(lan)轉彎和裕留電(dian)(dian)纜(lan)(lan)(lan)時，讓電(dian)(dian)纜(lan)(lan)(lan)處于自然(ran)彎曲(qu)，杜絕內部機械損傷現(xian)象。

2、大電(dian)流電(dian)力電(dian)纜引發的渦(wo)流

電(dian)(dian)(dian)(dian)力(li)電(dian)(dian)(dian)(dian)纜(lan)在(zai)(zai)施工中(zhong)，有(you)采(cai)用(yong)鋼(gang)支架(jia)的，有(you)采(cai)用(yong)鋼(gang)質保護(hu)管(guan)的，有(you)采(cai)用(yong)電(dian)(dian)(dian)(dian)纜(lan)卡與(yu)架(jia)空敷設的，凡是在(zai)(zai)電(dian)(dian)(dian)(dian)力(li)電(dian)(dian)(dian)(dian)纜(lan)周(zhou)Χ形(xing)(xing)成(cheng)鋼(gang)(鐵)性(xing)閉合回路，均有(you)可能形(xing)(xing)成(cheng)渦(wo)流(liu)，特(te)別是在(zai)(zai)大電(dian)(dian)(dian)(dian)流(liu)電(dian)(dian)(dian)(dian)力(li)電(dian)(dian)(dian)(dian)纜(lan)系統中(zhong)，渦(wo)流(liu)更(geng)大，所以電(dian)(dian)(dian)(dian)力(li)工程公司提醒，在(zai)(zai)電(dian)(dian)(dian)(dian)力(li)電(dian)(dian)(dian)(dian)纜(lan)施工時必須(xu)采(cai)取措施，使電(dian)(dian)(dian)(dian)纜(lan)周(zhou)Χ不能形(xing)(xing)成(cheng)鋼(gang)(鐵)性(xing)閉合回路，防(fang)止(zhi)電(dian)(dian)(dian)(dian)纜(lan)引起渦(wo)流(liu)現象發生。

3、注(zhu)意(yi)電(dian)力纜(lan)防潮(chao)問題

據了解，中(zhong)(zhong)、低壓(ya)電(dian)(dian)(dian)(dian)力電(dian)(dian)(dian)(dian)纜(lan)(lan)故障(zhang)大(da)部(bu)分是電(dian)(dian)(dian)(dian)纜(lan)(lan)中(zhong)(zhong)間(jian)接頭(tou)和(he)終端(duan)頭(tou)故障(zhang)，而中(zhong)(zhong)間(jian)接頭(tou)和(he)終端(duan)頭(tou)故障(zhang)則大(da)部(bu)分是因密(mi)(mi)封(feng)不良(liang)，潮(chao)氣侵入而造(zao)成絕(jue)緣(yuan)強度下(xia)降(jiang)。而中(zhong)(zhong)、低壓(ya)電(dian)(dian)(dian)(dian)力電(dian)(dian)(dian)(dian)纜(lan)(lan)網多(duo)采用樹枝狀供電(dian)(dian)(dian)(dian)方式，電(dian)(dian)(dian)(dian)纜(lan)(lan)終端(duan)頭(tou)數量較多(duo)，因此(ci)把好電(dian)(dian)(dian)(dian)纜(lan)(lan)終端(duan)頭(tou)和(he)中(zhong)(zhong)間(jian)接頭(tou)堵?密(mi)(mi)封(feng)關是保證(zheng)電(dian)(dian)(dian)(dian)纜(lan)(lan)安全可(ke)靠運行(xing)的重要措施(shi)之一。
