電(dian)力(li)講解：電(dian)力(li)安(an)裝中電(dian)纜施(shi)工的注意事項電(dian)力(li)安(an)裝是(shi)民生(sheng)工程之一，也是(shi)每個鄉村社(she)區(qu)都(dou)不可少的施(shi)工項目，然而(er)，無論大型或小型工程施(shi)工，其中電(dian)纜問題(ti)都(dou)是(shi)施(shi)工中核心的問題(ti)，而(er)且電(dian)纜工程直接涉及到人(ren)身安(an)全(quan)問題(ti)，必須引(yin)起高度(du)重視。

那(nei)么，電(dian)纜(lan)施工中(zhong)有哪些注意事項呢?

1、電力電纜的轉彎引起的機械性損(sun)傷(shang)：

由(you)于(yu)電力(li)電纜(lan)(lan)外徑(jing)較(jiao)大(da)，運輸、敷設比較(jiao)困(kun)難(nan),電力(li)電纜(lan)(lan)對轉彎(wan)半(ban)徑(jing)的要求也比較(jiao)嚴格，電纜(lan)(lan)施工過程中(zhong)，要盡可能減少電纜(lan)(lan)受到的扭力(li)，在電纜(lan)(lan)轉彎(wan)和(he)裕留電纜(lan)(lan)時(shi)，讓電纜(lan)(lan)處于(yu)自(zi)然(ran)彎(wan)曲，杜絕內部(bu)機械損傷(shang)現象。

2、大電流(liu)電力電纜引發的渦流(liu)

電(dian)(dian)(dian)(dian)力電(dian)(dian)(dian)(dian)纜(lan)(lan)在(zai)(zai)施工中(zhong)，有(you)采用(yong)鋼(gang)(gang)支(zhi)架的，有(you)采用(yong)鋼(gang)(gang)質保(bao)護管的，有(you)采用(yong)電(dian)(dian)(dian)(dian)纜(lan)(lan)卡與架空敷設的，凡是在(zai)(zai)電(dian)(dian)(dian)(dian)力電(dian)(dian)(dian)(dian)纜(lan)(lan)周Χ形(xing)(xing)成鋼(gang)(gang)(鐵(tie))性閉合(he)回路，均有(you)可能形(xing)(xing)成渦流(liu)，特(te)別是在(zai)(zai)大(da)電(dian)(dian)(dian)(dian)流(liu)電(dian)(dian)(dian)(dian)力電(dian)(dian)(dian)(dian)纜(lan)(lan)系統中(zhong)，渦流(liu)更大(da)，所以(yi)電(dian)(dian)(dian)(dian)力工程公司提醒，在(zai)(zai)電(dian)(dian)(dian)(dian)力電(dian)(dian)(dian)(dian)纜(lan)(lan)施工時必須采取(qu)措施，使電(dian)(dian)(dian)(dian)纜(lan)(lan)周Χ不能形(xing)(xing)成鋼(gang)(gang)(鐵(tie))性閉合(he)回路，防止電(dian)(dian)(dian)(dian)纜(lan)(lan)引起渦流(liu)現象發生。

3、注意電力纜防潮問題(ti)

據了解，中(zhong)、低壓(ya)電(dian)力(li)電(dian)纜故(gu)障(zhang)大部(bu)分是(shi)電(dian)纜中(zhong)間接頭(tou)和(he)終端頭(tou)故(gu)障(zhang)，而中(zhong)間接頭(tou)和(he)終端頭(tou)故(gu)障(zhang)則大部(bu)分是(shi)因(yin)(yin)密封(feng)不良(liang)，潮氣(qi)侵入而造(zao)成絕緣強度下降。而中(zhong)、低壓(ya)電(dian)力(li)電(dian)纜網多采用(yong)樹枝(zhi)狀(zhuang)供電(dian)方式(shi)，電(dian)纜終端頭(tou)數量較多，因(yin)(yin)此把好電(dian)纜終端頭(tou)和(he)中(zhong)間接頭(tou)堵(du)?密封(feng)關是(shi)保(bao)證(zheng)電(dian)纜安全可靠運(yun)行的重要措施(shi)之一(yi)。
