答(da)：電(dian)(dian)(dian)力電(dian)(dian)(dian)纜(lan)的選擇應遵照以下原則：①電(dian)(dian)(dian)纜(lan)的額定電(dian)(dian)(dian)壓要大于或等(deng)于安裝點供電(dian)(dian)(dian)系(xi)統的額定電(dian)(dian)(dian)壓；②電(dian)(dian)(dian)纜(lan)持(chi)續容許電(dian)(dian)(dian)流應等(deng)于或大于供電(dian)(dian)(dian)負載的最大持(chi)續電(dian)(dian)(dian)流；③線芯截面(mian)要滿足供電(dian)(dian)(dian)系(xi)統短

答(da)：①易(yi)安裝，因為(wei)它允(yun)許(xu)最小(xiao)彎曲半徑小(xiao)、且重(zhong)量(liang)輕；②不受線路(lu)落差限制(zhi)；③熱(re)性能好，允(yun)許(xu)工作溫度(du)高(gao)、傳(chuan)輸容量(liang)大；④電纜附件簡單，均(jun)為(wei)干式結構；⑤運行(xing)維(wei)護簡單，無漏油(you)問題；⑥價格較(jiao)低；⑦

答：夾具應無(wu)鐵(tie)件(jian)構成閉(bi)合磁路，這是因為當(dang)電(dian)纜線(xian)芯通過電(dian)流時，在其(qi)周圍產生磁力線(xian)，磁力線(xian)與通過線(xian)芯的電(dian)流大小成正(zheng)比，若使用(yong)鐵(tie)件(jian)等導磁材料，根(gen)據電(dian)磁感應可知，將在鐵(tie)件(jian)中產生渦流使
