電(dian)(dian)力講解：電(dian)(dian)力安裝中電(dian)(dian)纜施(shi)(shi)工的注意(yi)事項(xiang)電(dian)(dian)力安裝是(shi)民生工程(cheng)之一，也是(shi)每個鄉(xiang)村社區(qu)都不可少(shao)的施(shi)(shi)工項(xiang)目，然而，無論大型或小(xiao)型工程(cheng)施(shi)(shi)工，其中電(dian)(dian)纜問(wen)題(ti)都是(shi)施(shi)(shi)工中核(he)心的問(wen)題(ti)，而且電(dian)(dian)纜工程(cheng)直接涉(she)及到人身安全問(wen)題(ti)，必(bi)須引起高度(du)重視。

那(nei)么，電纜(lan)施(shi)工中有哪(na)些注意事(shi)項(xiang)呢?

1、電力電纜的轉彎引起(qi)的機(ji)械性損傷(shang)：

由于電(dian)(dian)力(li)(li)電(dian)(dian)纜外(wai)徑(jing)較(jiao)大，運輸(shu)、敷(fu)設(she)比(bi)較(jiao)困難,電(dian)(dian)力(li)(li)電(dian)(dian)纜對轉彎(wan)(wan)半徑(jing)的要(yao)求(qiu)也(ye)比(bi)較(jiao)嚴(yan)格，電(dian)(dian)纜施工過程中，要(yao)盡可能(neng)減少電(dian)(dian)纜受(shou)到的扭力(li)(li)，在電(dian)(dian)纜轉彎(wan)(wan)和裕留電(dian)(dian)纜時，讓電(dian)(dian)纜處于自(zi)然彎(wan)(wan)曲，杜(du)絕內部機(ji)械損(sun)傷現象(xiang)。

2、大電(dian)流電(dian)力電(dian)纜引發的渦流

電(dian)(dian)(dian)(dian)力(li)(li)(li)電(dian)(dian)(dian)(dian)纜(lan)(lan)在施工(gong)中(zhong)，有(you)采(cai)(cai)用鋼(gang)(gang)(gang)支(zhi)架的，有(you)采(cai)(cai)用鋼(gang)(gang)(gang)質保(bao)護管的，有(you)采(cai)(cai)用電(dian)(dian)(dian)(dian)纜(lan)(lan)卡與架空敷設的，凡是在電(dian)(dian)(dian)(dian)力(li)(li)(li)電(dian)(dian)(dian)(dian)纜(lan)(lan)周(zhou)Χ形(xing)成(cheng)(cheng)鋼(gang)(gang)(gang)(鐵(tie))性閉(bi)合(he)(he)回路，均有(you)可能形(xing)成(cheng)(cheng)渦(wo)流，特(te)別是在大(da)電(dian)(dian)(dian)(dian)流電(dian)(dian)(dian)(dian)力(li)(li)(li)電(dian)(dian)(dian)(dian)纜(lan)(lan)系(xi)統(tong)中(zhong)，渦(wo)流更大(da)，所以電(dian)(dian)(dian)(dian)力(li)(li)(li)工(gong)程(cheng)公(gong)司提醒，在電(dian)(dian)(dian)(dian)力(li)(li)(li)電(dian)(dian)(dian)(dian)纜(lan)(lan)施工(gong)時(shi)必須采(cai)(cai)取措施，使(shi)電(dian)(dian)(dian)(dian)纜(lan)(lan)周(zhou)Χ不能形(xing)成(cheng)(cheng)鋼(gang)(gang)(gang)(鐵(tie))性閉(bi)合(he)(he)回路，防止電(dian)(dian)(dian)(dian)纜(lan)(lan)引起渦(wo)流現象發生。

3、注意(yi)電力纜防潮問題

據(ju)了解，中、低壓(ya)電(dian)(dian)力電(dian)(dian)纜(lan)(lan)故障大(da)部分(fen)是電(dian)(dian)纜(lan)(lan)中間(jian)(jian)接(jie)頭和(he)終端頭故障，而(er)中間(jian)(jian)接(jie)頭和(he)終端頭故障則大(da)部分(fen)是因密封(feng)不良，潮氣(qi)侵(qin)入(ru)而(er)造成絕(jue)緣強(qiang)度(du)下降。而(er)中、低壓(ya)電(dian)(dian)力電(dian)(dian)纜(lan)(lan)網多(duo)采用樹枝狀供電(dian)(dian)方(fang)式，電(dian)(dian)纜(lan)(lan)終端頭數量較(jiao)多(duo)，因此把好電(dian)(dian)纜(lan)(lan)終端頭和(he)中間(jian)(jian)接(jie)頭堵?密封(feng)關是保證電(dian)(dian)纜(lan)(lan)安全可靠運行(xing)的重要措(cuo)施之(zhi)一。
