1、電線電纜型號的選擇選用電線電纜時，要考慮用途，敷設條件及安全性；例如：（1）根據(jù)用途的不同，可選用電力電纜、架空絕緣電纜、控制電纜等；（2）根據(jù)敷設條件的不同，可選用一般塑料絕緣電纜、鋼帶鎧裝電纜、鋼絲鎧裝電纜、防腐電纜等；（3）根據(jù)安全性要求，可選用阻燃電纜、無鹵阻燃電纜、耐火電纜等。 2、電線電纜規(guī)格的選擇確定電線電纜的使用規(guī)格（導體截面）時，一般應考慮發(fā)熱，電壓損失，經(jīng)濟電流密度，機械強度等選擇條件。根據(jù)經(jīng)驗，低壓動力線因其負荷電流較大，故一般先按發(fā)熱條件選擇截面，然后驗算其電壓損失和機械強度；低壓照明線因其對電壓水平要求較高，可先按允許電壓損失條件選擇截面，再驗算發(fā)熱條件和機械強度；對高壓線路，則先按經(jīng)濟電流密度選擇截面，然后驗算其發(fā)熱條件和允許電壓損失；而高壓架空線路，還應驗算其機械強度。若用戶沒有經(jīng)驗，則應征詢有關專業(yè)單位或人士的意見。天津民用電線電纜改造需要多少錢電線電纜是國家經(jīng)濟建設中的一項重要產業(yè)。</p><div

用于信息傳輸系統(tǒng)的電線電纜主要有市話電纜、電視電纜、電子線纜、射頻電纜、光纖纜、數(shù)據(jù)電纜、電磁線、電力通訊或其他復合電纜等。 3、機械、儀表系統(tǒng) 此部分除架空裸電線外幾乎其他所有產品均有應用，但主要是電力電纜、電磁線、數(shù)據(jù)電纜、儀器儀表線纜等。使用電纜保護套管保護電纜的優(yōu)勢：強度高、剛度高。</p><div
