單(dan)級安(an)(an)全滑(hua)(hua)觸(chu)線(xian)(xian)又稱滑(hua)(hua)觸(chu)線(xian)(xian)，滑(hua)(hua)線(xian)(xian)，安(an)(an)全滑(hua)(hua)線(xian)(xian),還可被稱為(wei)行車滑(hua)(hua)觸(chu)線(xian)(xian)，起重機滑(hua)(hua)觸(chu)線(xian)(xian)。安(an)(an)全滑(hua)(hua)觸(chu)線(xian)(xian)用于(yu)(yu)給移(yi)動(dong)(dong)中的設備(bei)供電(dian)，由(you)兩部分(fen)組成(cheng)，滑(hua)(hua)線(xian)(xian)導(dao)軌(gui)（固定(ding)部分(fen)，與(yu)電(dian)源相接(jie)，常導(dao)軌(gui)由(you)單(dan)長(chang)4m/根或者(zhe)6米/根連接(jie)而成(cheng)），集電(dian)器（滑(hua)(hua)動(dong)(dong)部分(fen)，可在滑(hua)(hua)線(xian)(xian)軌(gui)道(dao)上或內滑(hua)(hua)動(dong)(dong)并與(yu)銅條接(jie)觸(chu)取電(dian)，集電(dian)器用于(yu)(yu)與(yu)移(yi)動(dong)(dong)電(dian)機相連）。

安全(quan)滑(hua)(hua)觸線(xian)(xian),安全(quan)絕緣,防(fang)(fang)火阻(zu)燃,耐溫(wen),抗老化,防(fang)(fang)塵(chen)防(fang)(fang)腐(fu)蝕,防(fang)(fang)日曬雨淋. 安全(quan)滑(hua)(hua)觸線(xian)(xian)用(yong)于各種(zhong)行業的(de)橋式起重機,行車(che)天車(che)運輸機械等移(yi)動供電.

單極(ji)(ji)安(an)全滑(hua)觸線(xian)(xian)沿縱長方向用(yong)PVC塑(su)料(liao)作整體保護除(chu)下(xia)部開口處與(yu)導電器接觸處外。因此安(an)裝(zhuang)后滑(hua)線(xian)(xian)沒有導電外露部分。給安(an)裝(zhuang)和(he)維修帶(dai)來極(ji)(ji)大(da)方便。滑(hua)線(xian)(xian)整體塑(su)殼保護后使(shi)之(zhi)具備預(yu)防積灰、雨(yu)、露、冰雪侵襲之(zhi)功能，導軌(gui)與(yu)導軌(gui)之(zhi)間的連(lian)(lian)接采用(yong)專用(yong)連(lian)(lian)接器，能使(shi)導軌(gui)和(he)塑(su)料(liao)外殼同時(shi)伸入其間，故連(lian)(lian)接端同樣(yang)安(an)全可靠。
