One in and five out cable distribution box DFW distribution box

Types of cable distribution boxes Cable distribution boxes are divided into two categories according to their electrical composition. The first category does not contain any switching equipment. There are only accessories for processing and connecting cable ends in the box. The structure is relatively simple and the volume is relatively small. Small, with a single function, it can be called an ordinary tap box. The other type is a box that not only contains the accessories of an ordinary tap box, but also contains one or more switchgear. Its structure is relatively complex, the volume is large, and there are many connecting devices. , the manufacturing technology is difficult and the cost is high, so it can be called a high-end distribution box.
Through tap box
There is no switching device in the ordinary tap box. The incoming and outgoing wires are electrically connected together and have the same potential, so they are suitable for tap or branch wiring. It is usually customary to add the number of incoming lines to the number of outgoing lines as the number of branches. For example, a three-branch cable distribution box has three equipotential connection points on each phase, which can be used as one in and two out or two in and one out. The cable distribution box contains three phases. The three-phase circuit structures are the same and arranged together in sequence.
Grade tap box
The advanced tap box contains switch equipment, which can not only function as a tap branch of an ordinary tap box, but also control and convert the power supply circuit and change the operating mode. The switch break roughly separates the cable circuit into the incoming side and the outgoing side, and the potentials on both sides can be different. The switchgear itself has a large volume, so the overall dimensions of the high-end distribution box are relatively large. The height is generally about 100cm and the depth is about 10cm. The length depends on the number of switchgear devices contained, mostly in the middle. The shape of the box is similar to that of an outdoor box-type transformer. There are several movable doors on the box. Some doors are designed for the operation of switching equipment, and some doors are designed for the installation, construction or maintenance of cable connection devices. .
