在一條距離比較長的線路上有多根小面積電纜往往會造成電纜使用浪費，大理交流充電樁價格于是在出線到用電負荷中，往往使用主干大電纜出線，生產交流充電樁價格然后在接(jie)近負荷的(de)時(shi)候，使用(yong)電(dian)(dian)纜分支箱將主干電(dian)(dian)纜分成若干小面(mian)積(ji)，電(dian)(dian)纜，由(you)小面(mian)積(ji)電(dian)(dian)纜接(jie)入負荷。這樣的(de)接(jie)線方式廣泛用(yong)于城市電(dian)(dian)網中的(de)路燈等供(gong)電(dian)(dian)、小用(yong)戶供(gong)電(dian)(dian)。
