Densebusduct,highstrengthenclosedbusduct(CFW)

    該工藝不受板材的限制，外殼做成華夫餅狀，提高了母線的機(jī)械強(qiáng)度，母線的水平截面可達(dá)13m，由于外殼的盤繞，凹槽的位置被有意分開(kāi)固定，母線之間的距離為18mm。線路間通風(fēng)良好，明顯提高了母線槽的防潮散熱功能，更適合華南地區(qū)的氣候；線路間有一定的空隙，會(huì)引起導(dǎo)線溫度的升降，從而提高了過(guò)載能力，降低了磁振蕩噪聲。但其雜散電流和電感電抗遠(yuǎn)大于密集型母線，因此其導(dǎo)電桿截面必須大于密集型絕緣插入式母線截面。

    由于總線之間的連接器和銅的軟結(jié)合，南方地區(qū)的天氣潮濕，連接器容易氧化，這使得連接器和總線之間的接觸不良，并使接觸點(diǎn)易于加熱，因此在南方地區(qū)很少使用。節(jié)點(diǎn)間體積過(guò)大，水平母線截面尺寸不一致，外形不美觀。

    密集絕緣插入式母線槽（CMC）

    其含水量和散熱效果較差。在防潮方面，母線在施工過(guò)程中容易受到潮濕和水的影響，導(dǎo)致相間絕緣電阻降低。客車的散熱主要取決于外殼。由于導(dǎo)線排列緊湊，L2和L3相的熱能分布緩慢，母線槽溫升很高。密集絕緣插入式母線只能產(chǎn)生不超過(guò)3m的水平段，受外板限制。由于母線間氣隙小，當(dāng)母線通過(guò)大電流時(shí)，會(huì)產(chǎn)生強(qiáng)大的電力，導(dǎo)致磁振蕩頻率疊加，產(chǎn)生過(guò)大的噪聲。插入式母線槽是一種干線系統(tǒng)，具有體積小、結(jié)構(gòu)緊湊、運(yùn)行可靠、傳輸電流大、分接饋電方便、維護(hù)方便、能耗低、動(dòng)態(tài)熱穩(wěn)定性好等優(yōu)點(diǎn)
