答(da)：電(dian)(dian)(dian)力電(dian)(dian)(dian)纜的(de)選擇應遵照以下(xia)原(yuan)則：①電(dian)(dian)(dian)纜的(de)額定電(dian)(dian)(dian)壓要大于或(huo)等(deng)于安裝點供電(dian)(dian)(dian)系統的(de)額定電(dian)(dian)(dian)壓；②電(dian)(dian)(dian)纜持(chi)續(xu)容許電(dian)(dian)(dian)流應等(deng)于或(huo)大于供電(dian)(dian)(dian)負載的(de)最大持(chi)續(xu)電(dian)(dian)(dian)流；③線芯(xin)截(jie)面要滿足供電(dian)(dian)(dian)系統短
了解詳(xiang)情
答(da)：①易安裝，因為它允許最小彎曲半徑小、且重量輕；②不受線(xian)路落差限制；③熱性能(neng)好，允許工作(zuo)溫度高、傳輸容量大；④電纜附(fu)件簡單(dan)(dan)，均(jun)為干式結(jie)構(gou)；⑤運(yun)行維護簡單(dan)(dan)，無漏油問題；⑥價格較低；⑦
了解詳情
答：夾具應(ying)(ying)無鐵件構成(cheng)閉(bi)合磁(ci)(ci)路，這是因為當電纜線芯通(tong)過電流時，在(zai)(zai)其(qi)周(zhou)圍產生(sheng)磁(ci)(ci)力線，磁(ci)(ci)力線與通(tong)過線芯的電流大小成(cheng)正比，若使用(yong)鐵件等導磁(ci)(ci)材料，根據(ju)電磁(ci)(ci)感應(ying)(ying)可(ke)知，將在(zai)(zai)鐵件中(zhong)產生(sheng)渦流使
