加拿大大型鋁厂,采用多芯鋁导綫代替普通的电压700伏的母綫向鋁电解槽供电。这可省去对母綫弯曲、切割、钻孔、及压紧固定等繁重作业,大大减少由于綫路太长造成的过多的联接点,并容易做成各种交叉。結果可节省初次投資10—20％槽子总电流容量为100000安,敷設18条导綫供电,每条导綫通电能力为6700—7500安,鋁綫截面为2840毫米~2,四根导綫結成一組(图1),用鋁的緩冲支撑及不銹鋼带装配成組,每組最大长度为28米。
Large Canadian aluminum mills use aluminum multiconductor cables instead of conventional 700 volt bus bars to supply aluminum cells. This eliminates the need for cumbersome bending, cutting, drilling, and pinching of the busbars, greatly reducing excessive connection points due to the long lines and easily making various kinds of crossovers. As a result, initial investment of 10-20% can be saved. The total current capacity of the tank is 100000A, and 18 conductors are laid. Each conductor has a capacity of 6700-7500A and an aluminum cross section of 2840mm2. One set (Figure 1), assembled with aluminum cushioning braces and stainless steel bands, each with a maximum length of 28 meters.
