滑觸線用于給移動中的(de)設備(bei)供電(dian)(dian)，由兩部(bu)分組成，滑線導軌（固(gu)定部(bu)分，與電(dian)(dian)源(yuan)相接，常導軌由單長(chang)4m/根(gen)或者6米(mi)/根(gen)連接而成），集電(dian)(dian)器

滑觸線(xian)集(ji)(ji)(ji)(ji)電(dian)(dian)(dian)器(qi)(qi)主(zhu)要有靴片、靴盒、彈簧、集(ji)(ji)(ji)(ji)電(dian)(dian)(dian)器(qi)(qi)支架、集(ji)(ji)(ji)(ji)電(dian)(dian)(dian)器(qi)(qi)支撐部分等部件組成(cheng)。集(ji)(ji)(ji)(ji)電(dian)(dian)(dian)器(qi)(qi)分為重型(xing)(xing)(xing)集(ji)(ji)(ji)(ji)電(dian)(dian)(dian)器(qi)(qi)和輕(qing)型(xing)(xing)(xing)集(ji)(ji)(ji)(ji)電(dian)(dian)(dian)器(qi)(qi)，選(xuan)擇輕(qing)型(xing)(xing)(xing)集(ji)(ji)(ji)(ji)電(dian)(dian)(dian)器(qi)(qi)還是重型(xing)(xing)(xing)集(ji)(ji)(ji)(ji)電(dian)(dian)(dian)器(qi)(qi)

機構結構設計合理(li)，具有工(gong)藝先(xian)進、造型美觀、表面平滑(hua)、薄厚一致，機械(xie)強度高，安(an)裝方便、抗腐蝕及(ji)老(lao)化(hua)的優(you)點

防火封堵是(shi)消防工程(cheng)設計中一個重(zhong)要組(zu)成(cheng)部(bu)分,同時(shi)又是(shi)一項容易(yi)被忽視的(de)工作，殊(shu)不知(zhi),火災的(de)形成(cheng),往(wang)往(wang)從那些隱(yin)蔽的(de)被人遺忘的(de)隱(yin)蔽部(bu)位發生,然后(hou)迅速蔓延,以致釀成(cheng)大禍,造(zao)成(cheng)嚴重(zhong)后(hou)果

網格(ge)式橋架的開(kai)放結構(gou)能讓線(xian)(xian)纜最(zui)大幅度的 通風散熱，跟裝在空氣中一(yi)樣，熱量不會聚集在橋架中，因此可以(yi)節約(yue)能耗，優化線(xian)(xian)纜性能
