電力(li)講解：電力(li)安裝中(zhong)電纜施(shi)(shi)工(gong)(gong)的注意事項電力(li)安裝是(shi)民生工(gong)(gong)程(cheng)之一，也是(shi)每個鄉村社區都不可少的施(shi)(shi)工(gong)(gong)項目，然(ran)而(er)，無論大型或小型工(gong)(gong)程(cheng)施(shi)(shi)工(gong)(gong)，其中(zhong)電纜問題都是(shi)施(shi)(shi)工(gong)(gong)中(zhong)核(he)心的問題，而(er)且電纜工(gong)(gong)程(cheng)直接涉及(ji)到人身安全問題，必須引起(qi)高度重視。

那么，電纜(lan)施工(gong)中有(you)哪些注意事項呢?

1、電力電纜(lan)的(de)轉彎引起的(de)機械(xie)性損傷：

由于電(dian)(dian)力(li)(li)電(dian)(dian)纜(lan)外徑較大(da)，運輸、敷設(she)比較困難,電(dian)(dian)力(li)(li)電(dian)(dian)纜(lan)對(dui)轉(zhuan)彎半徑的要(yao)求也比較嚴格，電(dian)(dian)纜(lan)施工過程中，要(yao)盡可能減少電(dian)(dian)纜(lan)受到的扭力(li)(li)，在(zai)電(dian)(dian)纜(lan)轉(zhuan)彎和裕留電(dian)(dian)纜(lan)時，讓電(dian)(dian)纜(lan)處于自然彎曲(qu)，杜(du)絕內(nei)部機械損(sun)傷(shang)現象。

2、大(da)電流電力(li)電纜引發的渦流

電(dian)(dian)力(li)(li)電(dian)(dian)纜(lan)(lan)(lan)在施工中(zhong)，有(you)(you)采(cai)用(yong)鋼(gang)(gang)支架的，有(you)(you)采(cai)用(yong)鋼(gang)(gang)質保(bao)護管(guan)的，有(you)(you)采(cai)用(yong)電(dian)(dian)纜(lan)(lan)(lan)卡與架空敷(fu)設的，凡是在電(dian)(dian)力(li)(li)電(dian)(dian)纜(lan)(lan)(lan)周(zhou)Χ形(xing)成(cheng)鋼(gang)(gang)(鐵)性閉(bi)合回(hui)路，均有(you)(you)可能(neng)形(xing)成(cheng)渦(wo)流(liu)(liu)，特別是在大電(dian)(dian)流(liu)(liu)電(dian)(dian)力(li)(li)電(dian)(dian)纜(lan)(lan)(lan)系統中(zhong)，渦(wo)流(liu)(liu)更大，所以電(dian)(dian)力(li)(li)工程公司提醒(xing)，在電(dian)(dian)力(li)(li)電(dian)(dian)纜(lan)(lan)(lan)施工時必須采(cai)取措施，使(shi)電(dian)(dian)纜(lan)(lan)(lan)周(zhou)Χ不能(neng)形(xing)成(cheng)鋼(gang)(gang)(鐵)性閉(bi)合回(hui)路，防止電(dian)(dian)纜(lan)(lan)(lan)引起渦(wo)流(liu)(liu)現(xian)象(xiang)發生。

3、注意(yi)電力纜(lan)防潮(chao)問題

據了解，中(zhong)(zhong)、低壓(ya)電(dian)(dian)力(li)(li)電(dian)(dian)纜故障(zhang)(zhang)大(da)部分是電(dian)(dian)纜中(zhong)(zhong)間(jian)接(jie)頭和(he)終端(duan)頭故障(zhang)(zhang)，而(er)中(zhong)(zhong)間(jian)接(jie)頭和(he)終端(duan)頭故障(zhang)(zhang)則大(da)部分是因(yin)密(mi)封不良，潮氣侵入而(er)造成絕緣強度下降。而(er)中(zhong)(zhong)、低壓(ya)電(dian)(dian)力(li)(li)電(dian)(dian)纜網(wang)多(duo)采用(yong)樹枝(zhi)狀(zhuang)供電(dian)(dian)方式，電(dian)(dian)纜終端(duan)頭數量較多(duo)，因(yin)此把(ba)好(hao)電(dian)(dian)纜終端(duan)頭和(he)中(zhong)(zhong)間(jian)接(jie)頭堵?密(mi)封關是保證電(dian)(dian)纜安(an)全可靠運行的重要措施之(zhi)一(yi)。
