Types and characteristics of cable branch box

Cable branch box's main function is to tap or transfer cables. With the more and more extensive application, there are more and more product modeling designs. Due to the different quality requirements of projects in different places, the model functions used are also different. Let me talk about the role of cable branch box and other related knowledge.

Types of cable branch box and their respective characteristics;

At present, cable branch box is divided into American branch box, European branch box and cable branch box with load switch.

1. American-style cable branch box: The American-style branch box is characterized by one-way door opening and transverse multi-channel bus bars, which has obvious advantages such as small width, flexible combination, complete insulation and complete sealing. According to the rated current, it can be generally divided into 600A main circuit and 200A branch circuit. 600A main circuit is fixedly connected with screw-in bolts; 200A branch adopts plug-in connection, which can be plugged and unplugged with load.

2. European-style cable branch box: The main feature of European-style cable branch box is that it opens doors in two directions, and adopts wall bushing as the connecting bus, which has obvious advantages such as short length, clear cable arrangement and no need for large-span crossing of three-core cables.

Generally, bolts with rated current of 630A are used to fix the connected cable joints. 3. On-load switch breaking cable branch box: The main feature of on-load switch breaking cable branch box is that it can break short circuit and load current in the line, and its branch box combination mode is simple, convenient and flexible, fully insulated, fully sealed, maintenance-free, safe and reliable. It can greatly save the investment of equipment and cables and improve the reliability of power supply. The advantage of the new cable branch box is that the incoming line is equipped with a protective device. Once a user loses power, only the corresponding faulty user is disconnected, and the normal power consumption of other users is not affected, which not only reduces the number of over-the-top trips, but also reduces the power outage area and improves the power supply reliability of distribution network users.

The role of cable branch box:

Cable distribution box is the supporting equipment for cable transformation in urban network.

It can be installed in outdoor, indoor or underground places, and can connect power cables with box-type transformers, load switch cabinets, negative-melting combined electrical cabinets, ring network power supply units, etc. , and plays the role of tap, shunt, relay or conversion, which provides great convenience for wired networking. Main features: prefabricated cable plug device is adopted, which has excellent performance of full insulation, full sealing, full waterproof, maintenance-free, safety and reliability. Cable plug-ins have various varieties and complete specifications, and are equipped in series: rated current: 200A, 400A, 630A rated voltage: 0.4kV.
