Bus duct is a new product developed in the United States. Use copper or aluminum as the conductor, support it with non-olefin insulation, and then install it in a metal channel to form the new conductor.

In 1954, Japanese companies truly solved practical applications, and the use of bus ducts has since gained social development. Nowadays, power systems have become an indispensable wiring method in electrical equipment such as high-rise buildings and factories.

Due to the electricity demand of various construction companies such as buildings and factories, and the needs of this development are increasing year by year, we have adopted our original circuit wiring design method, namely the pipe penetration method, which has caused many economic difficulties during construction. Moreover, when the distribution management system is to be changed, it is almost impossible to make it simple and understandable for some problems. However, if bus ducts can be used, it can easily achieve the purpose of teaching and make the building more beautiful.

Modern high-rise buildings and large factories require a large amount of electricity. Faced with such huge loads that require hundreds of thousands of amperes, safe and reliable conduction equipment must be selected. Busbar systems are a good choice. The busbar system is a power distribution device for enterprises to efficiently develop current transmission, especially to meet the needs of increasingly taller buildings and large production plants for economical structure and reasonable wiring.

Bus duct has gone through three generations from air type to composite insulation type.

The first generation air bus duct

Beginning in the mid-1950s, conductive strips were supported in the enclosure with insulating gaskets and insulated by the air ambient medium. The distance is 50 mm. In the humid climate of the south, due to the use of soft copper connections between busbar nodes, the busbar nodes are easily oxidized, resulting in poor contact between the busbar nodes and the busbar. Moreover, the volume between the joints is too large, the dimensions of the transverse busbar sections are inconsistent, and the shape design is not beautiful enough. The shell protection technical level is IP40~IP54.

The air bus duct uses copper bars to conduct electricity, and insulating spacers are added to separate the copper bars. The conductive strip is supported in the casing by an insulating gasket, and some metal material casing is installed for sealing. Insulated by the air environment medium, the distance between phases is 50mm. This bus duct is the primary basic technology in the development history of our country's bus duct. Due to defects in information technology, the busbars in the bus duct are exposed. When dust enters the system busbar due to moisture, the dust covers and agglomerates it, causing different short circuits between some conductive phase lines, causing accidents.

Second generation CCX, CMC, CFW

In addition to the conductive strip itself, the composite insulated busbar also has an insulating layer. The relationship between the phase lines also has a certain air environment dielectric insulation. In the later stage, four-way cross-linking was used to solidify the insulating layer, and there was no gap between the insulating layer and the conductive layer.

Third generation CCX2 type

Developed in the mid-1980s, conductive strips are covered with insulating structural material and then secured with two sides. A special type of bus produced during the evolution of the second generation bus is the intensive bus air socket. Due to changes in the production process, it can basically become a technology-intensive busbar-intensive socket, that is, an overall knowledge-intensive busway.

Fourth generation innovative application types

From the perspective of customer needs, we develop different field-specific bus slot products for different application fields;

▲The newly built energy-saving bus duct is used for power distribution in the factory of a large enterprise;

▲Cast busbars for outdoor and underwater use; fire-resistant busbars for emergency power fires;

▲Micropower busbar for large data computer rooms;

▲Used for lighting bus ducts in public service places such as large enterprise parking lots, stations, and airports.

Fifth generation: intelligent control energy-saving bus duct

▲Rely on Internet information technology to realize daily management and operation monitoring of bus ducts, discover and avoid financial risks in advance, and ensure the safety of enterprise operations.

▲The overall structure of the product has been upgraded. After the upgrade, it has better conductivity, insulation, energy saving, corrosion resistance and impact resistance than the previous generation busbar. The patented information technology of innovative enterprises that can be added to the application for installation and implementation makes implementation more convenient, and the overall social security will be improved in the future.

Innovative painting technology meets the needs of users, allowing the bus duct to become an artistic decorative space.
