BusbarIt is a closed metal device composed of copper and aluminum busbars, used to distribute more power to each component in a distributed system. The replacement of wires and cables in household low-voltage power transmission projects is increasing.

BusbarMade of copper or aluminum as the conductor, supported by a new type of non-olefin insulating material, and formed by placing it in a metal can.BusbarThe real application is in 1954 in JapanSince then, it has begun to develop. Today, it has become an indispensable wiring method for electrical equipment and power systems in high-rise buildings, factories, etc. Because the electricity demand of buildings is high, for example, the electricity demand of buildings increases year by year. Using the original wiring method, that is, the direct pipe method, will bring many difficulties to construction. In addition, it is almost impossible to reform the allocation system to make it simpler. But if you useBusbarmode, it is easy to achieve the goal, and it can also make the building more beautiful. Economically,BusbarThe Price itself is slightly higher than that of cables, but compared with various accessories, including wiring and the entire power system,Busbarthe construction cost is much lower, especially in the case of large current capacity.

With the advent of modern engineering facilities and equipment, the electricity consumption of various industries has rapidly increased, especially with the emergence of a large number of high-rise buildings and large factories. Traditional power transmission lines in the form of cables can no longer meet the requirements of high-current power transmission systems, and the use of multi-channel cables brings inconvenience to on-site installation and construction.BusbarThe plug is a new type of power distribution wire.

Compared with traditional cables, its advantages are fully reflected under high-current transmission conditions. At the same time, due to the adoption of new technologies and processes,Busbarthe contact resistance and temperature rise of the two-end connection parts and the branch port plug-in parts are greatly reduced,BusbarInsulating materials are used to improveBusbarsafety and reliability, making the whole system more perfect.

ClosedBusbar(AbbreviationBusbar) is a busbar system composed of metal plates (steel plates or aluminum plates) used to protect the shell, insulating materials, and related accessories.

The present invention can manufacture an insertable closed busbar with insertion-type junction boxes within a certain distance, or a feeder closed busbar without insertion-type junction boxes in the middle.

In the power supply system of high-rise buildings, power and lighting lines are usually set up separately,Busbaras the backbone of power supply, vertically installed along the wall in the electrical well once or several times.

BusbarGenerally, it consists of the frontBusbar、Busbarthrough(strip and non-strip), L-shaped vertical (horizontal) cable busbar, Z-shaped vertical (horizontal) offsetBusbar、T-shaped vertical (horizontal) three-wayBusbar、X-shaped vertical (horizontal) four-way busbar, varactor diodeBusbarexpansionBusbarend-to-end, junction boxes and plug boxes. According to the insulation method,Busbarcan be divided into air plug-insBusbarhigh insulation density plug-insBusbarand high strength plug-insBusbar. According to its structure and application, it can be divided into dense insulation, air insulation, air-added insulation, fireproof insulation, resin insulation and sliding contact insulation. According to its shell material, it can be divided into steel shell, aluminum shell and steel-aluminum mixed shellBusbar。

BusbarCopper rods or aluminum plates are used as conductors, with large current capacity, good electrical and mechanical properties, and a metal can as the shell, so it has strong burning resistance, safety and reliability, and a long service life. Compared with traditional power distribution or comparison, the equipment footprint is greatly reduced, the appearance is beautiful, and it is very beneficial to the construction and power distribution of large buildings.
