密集型母線(xian)槽適(shi)(shi)用于(yu)交流(liu)三相(xiang)四線(xian)、三相(xiang)五線(xian)制，頻(pin)率50~60Hz，額定電壓(ya)至690V,額定工作電流(liu)250~5000A的供配(pei)電系(xi)統，作為工礦、企(qi)事(shi)業和高層建筑中(zhong)供配(pei)電設(she)備的輔助(zhu)設(she)備，特別適(shi)(shi)用于(yu)車間(jian)、老企(qi)業的改造。
密集型母線(xian)槽結構特(te)點:
1）散熱(re)能力較(jiao)強(qiang)
密集型母線槽相(xiang)與相(xiang)及相(xiang)與外殼均緊貼在一起(qi)，故(gu)能(neng)(neng)承(cheng)受(shou)較(jiao)大的電動應力和熱應力。并能(neng)(neng)將(jiang)導電排所產生(sheng)的熱量迅速(su)散發，載流量大。
接(jie)頭用絕緣螺栓(shuan)緊固(gu)，同時采用雙連接(jie)銅(tong)排連接(jie)，有效增(zeng)加了接(jie)頭接(jie)觸面積，大(da)大(da)降低了接(jie)頭部位(wei)溫升。
2）新(xin)一代環保產品
密(mi)集(ji)型母線槽(cao)導(dao)電排纏繞有(you)(you)阻(zu)燃型交(jiao)聯聚乙烯熱(re)縮套管，具有(you)(you)較(jiao)強的絕(jue)緣(yuan)性能(neng)，在(zai)遇火時無有(you)(you)毒氣體散發。
3）布線靈活
密集型(xing)母線槽(cao)插接口設置靈活方(fang)便，可設置大量(liang)的插口，通用(yong)性較強，當調整(zheng)用(yong)電(dian)設備位置時(shi)，無需變動供電(dian)系統。

高強度封閉母(mu)線(xian)槽。
其工(gong)藝制(zhi)造不受板(ban)材限(xian)制(zhi)，外(wai)殼做(zuo)成瓦溝(gou)形(xing)式(shi)，使(shi)(shi)(shi)母(mu)(mu)線(xian)機械強度(du)增加，母(mu)(mu)線(xian)水平段可生產至１３ｍ長。由于外(wai)殼做(zuo)成瓦溝(gou)形(xing)式(shi)，坑溝(gou)位置有(you)意將母(mu)(mu)線(xian)分隔固(gu)定，母(mu)(mu)線(xian)之間有(you)１８ｍｍ的(de)間距(ju)，線(xian)間通風良好，使(shi)(shi)(shi)母(mu)(mu)線(xian)槽(cao)(cao)的(de)防潮和散熱功能有(you)明顯的(de)提高(gao)，比較適應南方(fang)氣候；由于線(xian)間有(you)一定的(de)空(kong)隙，使(shi)(shi)(shi)導(dao)線(xian)的(de)溫升下降，這樣就(jiu)提高(gao)了過載能力(li)，并(bing)減少了磁(ci)振蕩噪聲。但它(ta)產生的(de)雜散電流及感抗(kang)要(yao)比密(mi)集型母(mu)(mu)線(xian)槽(cao)(cao)大得(de)多(duo)，因此在(zai)同(tong)規格比較時，它(ta)的(de)導(dao)電排截面必須比密(mi)集絕(jue)緣插(cha)接母(mu)(mu)線(xian)槽(cao)(cao)大。
