1. Bus line refers to the copper (copper for busbars) and aluminum material made of high conductivity, which is used to transmit electricity and have products that collect and distribute power. A total conductor for transmission of electricity from a power station or substation. Through it, the power generated by the generator, transformer or rectifier is transmitted to individual users or other substations.
2. A line that is mathematically defined by the motion of a certain condition.
With the emergence of modern engineering facilities and equipment, power consumption surge in all walks of life, especially the emergence of many high-rise buildings and large workshop, as a traditional power transmission conductor cable in the large current conveyor system can not meet the requirements, the multiplex the parallel to the on-site installation of the cable connection brings much inconvenience. Plug type electrical bus bar as a new type of power distribution wire arises at the historic moment, compared with the traditional cable, when large current conveyor fully embodies its superiority, at the same time, the adoption of new technology, new process, greatly reduces the bus duct department joint or line mouth plug on both ends of the contact resistance and the temperature rise, and USES the high quality in the bus duct insulation materials, so as to improve the safety and reliability of the bus duct, make the system more perfect.
A bus bars manufacturers is a system of metal plates (steel plates or aluminum plates) for the protection of housing, conductive, insulating materials and related accessories. It can be made into a standard length section, and it is equipped with a split-junction box every other distance, which can also be made into a feeder type closed bus line with a junction box. It has brought great convenience to feed and install overhaul.
According to the development of the insulated way, the development of the bus slot has been experienced in the three-generation products of the air type plug, dense insulation plug, and high strength composite insulated plug. The busbar can be used as L+N+ PE, L1+L2+ L3, L1+L2+L3+ L3+ N, L1+L2+L3+N+PE system to set up the power conductor and protect the conductor to meet the needs of the load.
The plug - type bus groove is for ac three-phase four-wire or five-wire system, suitable for frequency 50 ~ 60Hz, rated current
100A ~ 6300A, rated voltage to 690V for distribution and distribution, especially for low-voltage distribution systems and high-rise residential buildings, hotels, hospitals and other power supply systems in industrial plants and mines.
In the power system, the bus connects the various current branch circuits of the power distribution device, and plays the role of collecting, distributing and transmitting electricity.
