分支電(dian)纜的敷(fu)設對(dui)(dui)(dui)安裝(zhuang)(zhuang)(zhuang)人員的素質(zhi)要(yao)求較低，不同于母(mu)線槽(cao)，出廠(chang)后必須在現(xian)場(chang)連(lian)(lian)接拼裝(zhuang)(zhuang)(zhuang)。母(mu)線槽(cao)在用螺栓(shuan)(shuan)(shuan)連(lian)(lian)接時要(yao)保證適(shi)中的接頭力矩，這對(dui)(dui)(dui)安裝(zhuang)(zhuang)(zhuang)工人的要(yao)求較高。普(pu)(pu)通的母(mu)線槽(cao)廠(chang)家在現(xian)場(chang)安裝(zhuang)(zhuang)(zhuang)時對(dui)(dui)(dui)這方面沒有要(yao)求，安裝(zhuang)(zhuang)(zhuang)人員也僅(jin)用普(pu)(pu)通扳手憑感(gan)覺擰(ning)緊螺栓(shuan)(shuan)(shuan)。實際上，共(gong)箱封閉母(mu)線槽(cao)供應，現(xian)場(chang)螺栓(shuan)(shuan)(shuan)連(lian)(lian)接得過緊、過松都會對(dui)(dui)(dui)母(mu)線的內在性能質(zhi)量產(chan)生(sheng)潛(qian)在的影響。
