10kV high-voltage cable branch box products are as follows:

cable box is a device for the implementation of cable lines, branch, connection and conversion circuit equipment, mostly for outdoor. The equipment in our country the use of time is not long, the personage inside course of study of electric power system and department awareness and understanding of it is not consistent, especially of a quote from abroad European and American plug devices, such as the existence of different views. The following is a brief introduction and discussion of the relevant technical elements of cable trunk, for power design and operation department reference. The cable branch box type < cable branch box according to the electrical form into two categories: a class is not containing any switching equipment, the box body only of the cable terminal head for processing and connecting accessories, structure is simple, volume small, function of a single, universal common denominator in a box; another box not only ordinary branch box accessories, also contains one or more switching devices, its structure is more complex, larger, connector pieces, technical difficulty to manufacture large, high cost, for the senior branch box.

1. ordinary cable branch box < ordinary branch box is not switching equipment, wire connected together on the electrical, the same potential, suitable for tap or branch connection. Usually used to line number plus outlet called branches. For example, three branch cable branch box, each of which has three equal potential connection points, can be used as one into two or two into one. Cable box containing U, V, W three-phase, three-phase structure of the same structure, along the line.

2. senior cable branch box < senior branch box to contain switch equipment, which has an ordinary branch box tap, the role of the branch and up power supply circuit control, conversion and change the operation mode. The switch fracture generally separates the cable circuit into the inlet and outlet side, and the potential can be different. Switching equipment itself has a larger volume, so the shape and the size of the senior branch box is relatively large, the height is generally 1.4 ~ 1.8 m, depth of about 0.9 to 1.0 m, length according to the number of switching devices and, in 1.0 m to 2.4 m between. Body shape is similar to an outdoor box type transformer, box shell has a plurality of movable door, the gate is for switch equipment operation, some is
