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

The cable branch box is a kind of equipment which is used to carry out tap, branch, connection and conversion circuit of cable line. Most of the equipment is used in our country. The equipment is not used in our country for a long time. The industry and the power system use department know it. Understanding of the inconsistent, especially from the foreign European and American plug-in devices such as the existence of different views. The following cable branch box of the relevant technical elements for a brief introduction and discussion, for the power design and operation of the sector reference. type

The cable branch box according to its electrical composition is divided into two categories: one is not any switching equipment, the box only the cable end of the processing and connection of the attachment, the structure is relatively simple, smaller, Can be called ordinary branch box; the other is not only the general box of the box annex, also contains one or more switchgear, its structure is more complex, larger, more connected devices, manufacturing technology is difficult, cost High, can be called advanced branch box.

1. Ordinary cable branch box

Ordinary branch box without switching equipment, into the line and outlet in the electrical connection together, the same potential, suitable for tapping or branch wiring.Usually used to back into the line with the number of outlet called the number of branches. Branch box, each phase has three equipotential bonding points, can be used as one into the two or one out. Cable branch box containing U, V, W three-phase, three-phase circuit structure, the same Together.

2. Advanced cable branch box

The high-level branch box contains the switching equipment, which can act as the branching and branching function of the ordinary branch box, but also the control, the conversion and the change the operation mode of the power supply circuit.The switch fracture divides the cable circuit into the line side and the outlet The height of the high-level branch box is relatively large, the height is generally 1.4 ~ 1.8 m, the depth is about 0.9 ~ 1.0 m, the length is according to the included switch The number of devices, and more in the 1.0 m to 2.4 m between the box shape similar to the outdoor box-type transformer, the box has a number of activities of the door, and some doors for the operation of the switch device, and some The door is designed for installation or maintenance of cable connection devices
