　　1、具有優良的(de)供(gong)電可(ke)靠性

　　（1）主干電纜(lan)導體無(wu)接頭(tou)，連(lian)續性好，減少(shao)了故障點。

　　（2）預制分支電纜(lan)接頭采用工廠全程機械(xie)化制作，大大降低了人為因(yin)素造成(cheng)質量不穩定現象。

　　（3）分支(zhi)接頭(tou)結構合理并引(yin)進日(ri)本(ben)先進工藝制作(zuo)，接觸電阻極小，不受熱脹冷縮影響。

　　（4）短時間(jian)完成(cheng)(cheng)分支接(jie)頭成(cheng)(cheng)型，避免了接(jie)頭處銅導體長時間(jian)暴露(lu)空氣中(zhong)產生氧化(hua)而導致(zhi)接(jie)觸電阻變(bian)化(hua)。

　　2、可明顯降低配電成本(ben)

　　與母(mu)線槽比(bi)，可降低工程造價，并(bing)且技術經(jing)濟(ji)指標高，綜(zong)合經(jing)濟(ji)效益(yi)顯著。

　　3、品種規格多，選(xuan)用靈活，任意組合

　　（1）主干電纜從10 mm 2~630 mm 2,支線電纜從6 mm 2~400 mm 2任意(yi)組(zu)合。

　　（2）電纜的(de)品(pin)種(zhong)較多，主要有FZ-VV、FZ-ZR-VV、FZ-NH-VV、FZ-YJV、FZ-ZR-YJV、FZ-NH-YJV、FZ-WL-ZR-YJE、FZ-DL-NH-YJV等，可根據需(xu)要選(xuan)用。

　　（3）分(fen)支接頭可根(gen)據樓層需要任意(yi)設定分(fen)支位(wei)置(zhi)。

　　4、安裝(zhuang)環境要求低、施工方便(bian)

　　（1）占用(yong)建(jian)(jian)筑面積小，有(you)(you)利于建(jian)(jian)筑面積的有(you)(you)效使用(yong)，對土建(jian)(jian)的空間尺寸要求低。

　　（2）使(shi)用環(huan)境要求(qiu)低，安裝(zhuang)精度要求(qiu)低。

　　（3）安(an)裝簡單方便，安(an)裝技術要求不高(gao)，安(an)裝設備僅(jin)需一(yi)臺卷繞機(ji)即可，且安(an)裝周期短，僅(jin)為母線槽安(an)裝工時的(de)5%-10%，安(an)裝勞動強度低。

　　（4）由于電纜的(de)彎曲半徑(jing)小，大大降低了(le)安(an)裝難度，縮小了(le)空間尺寸。

　　5、優良的(de)抗震(zhen)性(xing)、氣(qi)密性(xing)、防水性(xing)和耐火性(xing)

　　（1）優良的抗(kang)震(zhen)性，一(yi)般機械連接母線槽接頭，在墻體震(zhen)動(dong)(dong)后會發生(sheng)接頭松動(dong)(dong)，而預(yu)制分支電纜則不會受到影響。特(te)別是在通過建筑沉降(jiang)縫時不需(xu)要任何(he)措(cuo)施。
