2)根據(jù)電線電纜型號(hào)的選擇確定電線電纜導(dǎo)體截面的時(shí)候,一般都應(yīng)該考慮產(chǎn)品的發(fā)熱,電壓的損失,經(jīng)濟(jì)電流的密度以及機(jī)械強(qiáng)度等等諸多的條件再進(jìn)行選擇電纜線型號(hào)。小編根據(jù)以往的經(jīng)驗(yàn)來(lái)判斷:
1.低壓動(dòng)力線因?yàn)槠浔旧淼呢?fù)荷電流會(huì)比較大,所以一般會(huì)先按照發(fā)熱條件進(jìn)行選擇導(dǎo)體截面,然后再去驗(yàn)算它的電壓損失以及機(jī)械強(qiáng)度;
2.低壓照明線會(huì)因?yàn)楫a(chǎn)品本身對(duì)電壓的水平要求比較高,就可以先按照條件允許的電壓損失進(jìn)行選擇截面,再去驗(yàn)算其發(fā)熱條件以及機(jī)械強(qiáng)度;
3.對(duì)于高壓線路來(lái)講,則必須先按照經(jīng)濟(jì)電流的密度進(jìn)行選擇導(dǎo)體截面,然后再去驗(yàn)算其發(fā)熱的條件以及其本身允許的電壓損失;
4.而對(duì)于高壓架空線路這種電纜線型號(hào),還應(yīng)該去驗(yàn)算它的機(jī)械強(qiáng)度。
廣泛應(yīng)用于數(shù)控機(jī)械?冶金、石油天然氣、石油化工、化工、造紙印刷、紡織印染、機(jī)械、電子制造、汽車制造、煙草、塑膠機(jī)械、電力、水利、水處理/環(huán)保、市政工程、鍋爐供暖、能源、輸配電。
