絕(jue)緣(yuan)防護型母線（俗稱動力母線）指用(yong)高導電(dian)(dian)(dian)率的銅(tong)質(zhi)、鋁質(zhi)導電(dian)(dian)(dian)材料制成的，外(wai)面附有特殊絕(jue)緣(yuan)外(wai)殼，用(yong)以傳輸(shu)電(dian)(dian)(dian)能(neng)，具(ju)有匯集和分配電(dian)(dian)(dian)能(neng)能(neng)力的產品。電(dian)(dian)(dian)站(zhan)或變(bian)電(dian)(dian)(dian)站(zhan)輸(shu)送(song)電(dian)(dian)(dian)能(neng)的總導線，以及輸(shu)電(dian)(dian)(dian)干(gan)線與用(yong)電(dian)(dian)(dian)設備(bei)支線間(jian)的供電(dian)(dian)(dian)，通過它，把發電(dian)(dian)(dian)機、變(bian)壓器或整(zheng)流器輸(shu)出的電(dian)(dian)(dian)能(neng)輸(shu)送(song)給各個用(yong)電(dian)(dian)(dian)設備(bei)。

主要優點

1、動力母線具有安全性能高;使用壽命長(chang)，同時具有安裝簡單、維護方便等(deng)優點

2、相比于電纜線(xian)(xian)(xian)，動(dong)力母(mu)線(xian)(xian)(xian)在車間使用，更為(wei)經(jing)濟(ji)實(shi)用，動(dong)力母(mu)線(xian)(xian)(xian)固定(ding)好位置(zhi)后(hou)，就不再移動(dong)，同時，有(you)專門的接線(xian)(xian)(xian)配(pei)件(jian)，相對于電纜線(xian)(xian)(xian)來講，更經(jing)濟(ji)實(shi)用。

3、可(ke)以更大(da)限(xian)(xian)度利用(yong)車間(jian)有(you)限(xian)(xian)空(kong)間(jian)，進行(xing)布局(ju)動(dong)(dong)力(li)母(mu)線(xian)。而(er)且(qie)動(dong)(dong)力(li)母(mu)線(xian)靈活度高(gao)，可(ke)以延伸到車間(jian)任何(he)移動(dong)(dong)設(she)備。

鋁基動力母線選型參考

1、根據車間(jian)所用設備的功率情況，選型(xing)鋁基動力母線。

2、一般情況設(she)計院(yuan)會(hui)設(she)計出電纜橋架的規格型號，可以(yi)根據規格型號計算出所需電流(liu)，然后(hou)選擇(ze)出合適的動力母(mu)線。

3、動力母線下線電流選型一般是主(zhu)線的(de)(de)一半，下線長(chang)度(du)需要根據鋼結構車間的(de)(de)立柱高度(du)來計算(suan)，有(you)些特殊(shu)情況需要去現場(chang)看看。
