單(dan)級(ji)滑觸線與(yu)多級(ji)管(guan)式滑觸線有什么區別？

單(dan)(dan)級(ji)(ji)滑(hua)觸(chu)(chu)(chu)線(xian)(xian)(xian)(xian)與多極管式滑(hua)觸(chu)(chu)(chu)線(xian)(xian)(xian)(xian)都屬于安全滑(hua)觸(chu)(chu)(chu)線(xian)(xian)(xian)(xian)，在本質(zhi)上(shang)沒什(shen)么區別，只是產品(pin)構造上(shang)不(bu)同(tong)，單(dan)(dan)級(ji)(ji)滑(hua)觸(chu)(chu)(chu)線(xian)(xian)(xian)(xian)一般是三線(xian)(xian)(xian)(xian)或者四線(xian)(xian)(xian)(xian)組合(he)起來使(shi)用(yong)。單(dan)(dan)級(ji)(ji)滑(hua)觸(chu)(chu)(chu)線(xian)(xian)(xian)(xian)每兩根線(xian)(xian)(xian)(xian)之間間距比較(jiao)大，另外單(dan)(dan)級(ji)(ji)滑(hua)觸(chu)(chu)(chu)線(xian)(xian)(xian)(xian)材質(zhi)分為銅和(he)鋁(lv)兩種。單(dan)(dan)級(ji)(ji)滑(hua)觸(chu)(chu)(chu)線(xian)(xian)(xian)(xian)適用(yong)于大型移(yi)(yi)動(dong)設(she)備(bei)移(yi)(yi)動(dong)供(gong)電(dian)使(shi)用(yong)。

多(duo)極滑(hua)觸線是由三根(gen)線或者(zhe)四根(gen)線在(zai)一(yi)根(gen)絕緣(yuan)護(hu)套內使用，結構(gou)比(bi)較緊湊，多(duo)極管(guan)式滑(hua)觸線只(zhi)有銅(tong)排一(yi)種．多(duo)極滑(hua)觸線只(zhi)適(shi)合于小型移動設備供電(dian)使用。
