電(dian)力(li)講解：電(dian)力(li)安(an)裝中電(dian)纜(lan)施(shi)工(gong)的注意事項電(dian)力(li)安(an)裝是(shi)民生工(gong)程(cheng)之一，也(ye)是(shi)每個鄉村社區都(dou)不可少的施(shi)工(gong)項目，然而(er)，無論大型或小型工(gong)程(cheng)施(shi)工(gong)，其中電(dian)纜(lan)問(wen)(wen)題(ti)都(dou)是(shi)施(shi)工(gong)中核心(xin)的問(wen)(wen)題(ti)，而(er)且電(dian)纜(lan)工(gong)程(cheng)直(zhi)接涉及到人(ren)身安(an)全(quan)問(wen)(wen)題(ti)，必須引起(qi)高度重(zhong)視。

那么，電(dian)纜施工(gong)中(zhong)有哪些注(zhu)意事項呢?

1、電力電纜(lan)的轉彎引起的機械性損傷(shang)：

由于電(dian)(dian)(dian)力電(dian)(dian)(dian)纜外(wai)徑較大，運輸、敷設比(bi)較困難,電(dian)(dian)(dian)力電(dian)(dian)(dian)纜對轉彎(wan)半徑的(de)要(yao)求也比(bi)較嚴格(ge)，電(dian)(dian)(dian)纜施工(gong)過程(cheng)中，要(yao)盡可(ke)能減少(shao)電(dian)(dian)(dian)纜受到的(de)扭力，在電(dian)(dian)(dian)纜轉彎(wan)和(he)裕(yu)留電(dian)(dian)(dian)纜時，讓(rang)電(dian)(dian)(dian)纜處于自然(ran)彎(wan)曲，杜絕內部(bu)機械損傷(shang)現(xian)象。

2、大(da)電(dian)流電(dian)力電(dian)纜(lan)引發的渦(wo)流

電(dian)(dian)(dian)力電(dian)(dian)(dian)纜在(zai)(zai)施工中(zhong)，有(you)采(cai)用(yong)鋼(gang)支(zhi)架的，有(you)采(cai)用(yong)鋼(gang)質保護管(guan)的，有(you)采(cai)用(yong)電(dian)(dian)(dian)纜卡與架空敷設的，凡是(shi)在(zai)(zai)電(dian)(dian)(dian)力電(dian)(dian)(dian)纜周Χ形成鋼(gang)(鐵)性(xing)閉合回(hui)路，均(jun)有(you)可能(neng)形成渦流，特別(bie)是(shi)在(zai)(zai)大電(dian)(dian)(dian)流電(dian)(dian)(dian)力電(dian)(dian)(dian)纜系統中(zhong)，渦流更大，所(suo)以電(dian)(dian)(dian)力工程公(gong)司提醒，在(zai)(zai)電(dian)(dian)(dian)力電(dian)(dian)(dian)纜施工時必須采(cai)取措施，使電(dian)(dian)(dian)纜周Χ不能(neng)形成鋼(gang)(鐵)性(xing)閉合回(hui)路，防止(zhi)電(dian)(dian)(dian)纜引(yin)起渦流現象發生。

3、注意電力(li)纜(lan)防潮問題

據了解(jie)，中、低(di)壓(ya)電(dian)力(li)電(dian)纜(lan)(lan)(lan)故(gu)(gu)障大(da)部(bu)分是(shi)電(dian)纜(lan)(lan)(lan)中間接(jie)(jie)頭(tou)和終端頭(tou)故(gu)(gu)障，而中間接(jie)(jie)頭(tou)和終端頭(tou)故(gu)(gu)障則大(da)部(bu)分是(shi)因密(mi)(mi)封不良，潮氣(qi)侵入而造成絕緣強度下降。而中、低(di)壓(ya)電(dian)力(li)電(dian)纜(lan)(lan)(lan)網(wang)多采用樹枝狀供(gong)電(dian)方式，電(dian)纜(lan)(lan)(lan)終端頭(tou)數量較多，因此把(ba)好(hao)電(dian)纜(lan)(lan)(lan)終端頭(tou)和中間接(jie)(jie)頭(tou)堵?密(mi)(mi)封關是(shi)保證電(dian)纜(lan)(lan)(lan)安全可(ke)靠(kao)運(yun)行的重要措施之一。
