电缆分接作用。在一条距离比较长的线路上有多根小面积电缆往往会造成电缆使用浪费，于是在出线到 用电负荷中，往往使用主干大电缆出线，然后在接近 负荷的时候，使用电缆分支箱将主干电缆分成若干小面积电缆，由小面积电缆接入负荷。这样的接线方式广泛用于城市电网中的路灯等供电、小用户供电。电缆转接作用。在一条比较长的线路上，电缆的长度无法满足线路的要求，那就必须使用 电缆接头或者电缆转接箱，通常短距离时候采用电缆中间接头，但线路框格护坡模具 箱体护坡模具 华尔街铜牛 电阻柜 接地电阻柜 电缆保护接地箱 隔离墩模具 化粪池模具比较长的时候，根据经验在1000m以上的 电缆线路上，如果电缆中间有多中间接头，为了确保安全，会在其中考虑电缆分支箱进行转接。
Cable tapping function. There are many small area cables on a long distance line, which will cause waste of cable use. Therefore, in the outgoing line to the power load, the trunk large cable is often used for outgoing line, and then when approaching the load, the trunk cable is divided into several small area cables by the cable branch box, and the small area cable is connected to the load. This kind of connection mode is widely used in the power supply of street lamps and small users in urban power grid. Cable transfer function. In a relatively long line, if the length of the cable cannot meet the requirements of the line, the cable connector or cable transfer box must be used. Generally, the cable intermediate connector is used in a short distance, but when the line is relatively long, according to experience, if there are multiple intermediate connectors in the middle of the cable, in order to ensure safety, the cable branch will be considered Box for transfer
