單(dan)級滑(hua)觸線(xian)與多級管式滑(hua)觸線(xian)有什么區別？

單級(ji)滑(hua)(hua)(hua)觸(chu)線(xian)(xian)(xian)(xian)與多(duo)極管(guan)式滑(hua)(hua)(hua)觸(chu)線(xian)(xian)(xian)(xian)都屬(shu)于(yu)安(an)全滑(hua)(hua)(hua)觸(chu)線(xian)(xian)(xian)(xian)，在本(ben)質上(shang)沒(mei)什么區別，只是(shi)產(chan)品構造上(shang)不同(tong)，單級(ji)滑(hua)(hua)(hua)觸(chu)線(xian)(xian)(xian)(xian)一般是(shi)三線(xian)(xian)(xian)(xian)或者四(si)線(xian)(xian)(xian)(xian)組(zu)合起來使用(yong)(yong)。單級(ji)滑(hua)(hua)(hua)觸(chu)線(xian)(xian)(xian)(xian)每兩(liang)(liang)根線(xian)(xian)(xian)(xian)之間間距比較大，另外單級(ji)滑(hua)(hua)(hua)觸(chu)線(xian)(xian)(xian)(xian)材質分為銅和(he)鋁兩(liang)(liang)種。單級(ji)滑(hua)(hua)(hua)觸(chu)線(xian)(xian)(xian)(xian)適用(yong)(yong)于(yu)大型移(yi)(yi)動設備移(yi)(yi)動供電使用(yong)(yong)。

多極(ji)滑(hua)觸線(xian)是由三根(gen)線(xian)或者四(si)根(gen)線(xian)在一根(gen)絕緣護套內(nei)使用，結構比(bi)較緊湊(cou)，多極(ji)管(guan)式滑(hua)觸線(xian)只(zhi)有銅(tong)排一種(zhong)．多極(ji)滑(hua)觸線(xian)只(zhi)適(shi)合(he)于小型移動設備供電使用。
