電力(li)(li)電纜(lan)在施(shi)工中，有(you)采用(yong)(yong)鋼支架的(de)，有(you)采用(yong)(yong)鋼質(zhi)保護管的(de)，有(you)采用(yong)(yong)電纜(lan)卡與架空敷(fu)設的(de)，凡是在電力(li)(li)電纜(lan)周(zhou)圍(wei)形(xing)成(cheng)(cheng)鋼（鐵）性(xing)(xing)閉合回路的(de)，均(jun)有(you)可能形(xing)成(cheng)(cheng)渦流，特(te)別(bie)是在大電流電力(li)(li)電纜(lan)系(xi)統中，渦流更大。在電力(li)(li)電纜(lan)施(shi)工時(shi)，***采取措施(shi)，使電纜(lan)周(zhou)圍(wei)不(bu)能形(xing)成(cheng)(cheng)鋼（鐵）性(xing)(xing)閉合回路，防止電纜(lan)引起渦流現象發生。

電(dian)(dian)(dian)(dian)(dian)力電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)的(de)(de)轉(zhuan)彎(wan)引起(qi)的(de)(de)機械性損(sun)傷(shang)(shang)問題由于(yu)電(dian)(dian)(dian)(dian)(dian)力電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)外(wai)徑較大(da)，運(yun)輸、敷設(she)(she)較為困難，電(dian)(dian)(dian)(dian)(dian)力電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)對轉(zhuan)彎(wan)半(ban)徑的(de)(de)要(yao)求(qiu)也比較嚴格。電(dian)(dian)(dian)(dian)(dian)力電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)在施(shi)(shi)工中，如果轉(zhuan)彎(wan)角度過大(da)，可能(neng)使導體內部(bu)受(shou)到機械損(sun)傷(shang)(shang)，而機械損(sun)傷(shang)(shang)因被電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)絕緣強度下降，直到出現故障，施(shi)(shi)工中發現一(yi)次電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)頭(tou)(tou)(tou)故障，在電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)頭(tou)(tou)(tou)制作時(shi)，三(san)根電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)頭(tou)(tou)(tou)長度一(yi)致，與設(she)(she)備連(lian)接(jie)時(shi)由于(yu)受(shou)地(di)形限制，中相電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)頭(tou)(tou)(tou)偏長而成為拱形，電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)頭(tou)(tou)(tou)根部(bu)受(shou)損(sun)放電(dian)(dian)(dian)(dian)(dian)。后(hou)采取(qu)措施(shi)(shi)，在設(she)(she)備的(de)(de)連(lian)接(jie)，適(shi)當縮短中相電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)頭(tou)(tou)(tou)連(lian)接(jie)長度，使三(san)相電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)頭(tou)(tou)(tou)均不受(shou)外(wai)力，實踐證明運(yun)行效果良好。由此可見(jian)，電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)施(shi)(shi)工過程中，要(yao)盡可能(neng)減少電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)受(shou)到的(de)(de)扭力，在電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)轉(zhuan)彎(wan)和裕(yu)留電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)時(shi)，讓電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)處于(yu)自然(ran)彎(wan)曲，內部(bu)機械損(sun)傷(shang)(shang)現象。

電(dian)力(li)纜防潮問(wen)題(ti)運(yun)行經驗表(biao)明(ming)，中(zhong)、低(di)壓電(dian)力(li)電(dian)纜故(gu)障(zhang)大部分(fen)為電(dian)纜中(zhong)間(jian)接(jie)頭(tou)和終(zhong)端(duan)頭(tou)故(gu)障(zhang)，而中(zhong)間(jian)接(jie)頭(tou)和終(zhong)端(duan)頭(tou)故(gu)障(zhang)則大部分(fen)是因密(mi)封不良，潮氣侵入(ru)而造成絕緣強度下(xia)降(jiang)，而中(zhong)、低(di)壓電(dian)力(li)電(dian)纜網(wang)多采用樹枝狀供(gong)電(dian)方式，電(dian)纜終(zhong)端(duan)頭(tou)數量較多，因此把好(hao)電(dian)纜終(zhong)端(duan)頭(tou)和中(zhong)間(jian)接(jie)頭(tou)堵(du)漏密(mi)封關是保證電(dian)纜安全(quan)可靠(kao)(kao)運(yun)行的重要(yao)措(cuo)施(shi)之一。在(zai)公用中(zhong)、低(di)壓電(dian)力(li)電(dian)纜網(wang)上(shang)，由(you)于三相負荷(he)不是相等(deng)的，因此，如果(guo)采用有(you)金屬(shu)護層的電(dian)纜，***考慮金屬(shu)護層的接(jie)地問(wen)題(ti)，并保證在(zai)金屬(shu)護層的任一點非接(jie)地處的正常感應電(dian)壓不得大于100V。我認為，在(zai)中(zhong)、低(di)壓電(dian)纜網(wang)中(zhong)，所(suo)有(you)電(dian)纜接(jie)頭(tou)處均(jun)應設置(zhi)接(jie)地極（網(wang)），并使(shi)金屬(shu)護層可靠(kao)(kao)接(jie)地。
