Busway was born in the United States, first put into practical use in Japan, and then spread all over the mountains and regions in prosperous countries and regions. So what is a busway? Busway is a high-current trunk tappable power supply system, usually composed of a metal shell (iron or aluminum), a conductor (copper or aluminum bar), insulation materials and related accessories.
In recent years, with the construction of many basic equipment, people's demand for electricity is also increasing, and bus duct has gradually become the standard power supply method for industrial plants, high-rise buildings, commercial complexes and rail transit.
Busway is a closed metal device composed of copper and aluminum busbars, which is used to distribute large power to each component of the dispersion system. Wires and cables have been increasingly replaced in indoor low-voltage power transmission trunk projects. To put it simply, the busway is a long iron box for placing cables, covering the lid from the top to close the distribution cable (the cable that supplies the main power supply is not necessarily a copper bar, and the copper bar is not allowed to be closed) in between.
Because the bus bar is often very long, the iron box is actually connected together in many sections, and the joint end of each iron box should be connected with a soft wire (usually a soft copper belt), and finally a good grounding is made at the end to ensure that the leakage will not damage the human body. To use professional terms, the busway is a safe and reliable conduction equipment in order to face the huge electrical energy required by modern high-rise buildings and large workshops, and the strong current of hundreds or thousands of amperes.
The busway system is a kind of high-efficiency power distribution equipment, especially suitable for the needs of high-rise buildings and large factories for reasonable wiring. With the presentation of modern engineering equipment and equipment, the electricity consumption of all walks of life has increased rapidly, especially many high-rise buildings and large factories. The traditional cable as a transmission line can no longer meet the requirements of the high-current transmission system, and the parallel use of multiple cables has brought a lot of inconvenience to the on-site device and construction connection. As a new type of distribution wire, the bus duct came into being. Compared to conventional cables, it abundantly shows its advantages in terms of high current transmission. At the same time, because of the use of new technology and technology, the contact resistance and temperature rise at the junction of the two ends of the bus duct and the splicing of the branch port are greatly reduced, and the bus duct adopts high-quality insulating materials, which improves its safety and reliability and makes the whole system more perfect.
