Conventional rectangular bus has not been able to meet people's standards, the need for a high-performance replacement, Insulation aluminum tube busbar with its high performance, high quality into the field of vision, trusted.
Insulation aluminum tube busbar , the essence is the use of aluminum tube as a conductor, external insulation of a kind of bus products.And the corresponding insulation copper busbar. Insulation aluminum tube busbar with large current, the current maximum can reach 12000A, high mechanical strength, good insulation, wide range of application and other characteristics, so more and more customers recognized and accepted.
Conventional rectangular bus is more and more difficult to meet the requirements of bus heating and short circuit electric power technically and structurally, which leads to additional loss, increase of skin effect coefficient, decrease of interception capacity and uneven distribution of current.Especially when the capacity of a single main transformer is 180MVA or above, the 10kV outgoing side of the main transformer not only has the electrodynamic and heating problems of the bus bridge itself, but also has the heating problems caused by induced eddy currents in the electromagnetic field caused by the post insulator of the bus bridge, the steel frame, the concrete upper column near the bus bridge and the steel bar in the foundation.
Insulation aluminum tube busbar as a replacement for rectangular bus.It has the following characteristics.
1. Large carrying capacity
2. Good insulation
3. High mechanical strength
4. Good heat dissipation, low temperature rise and low loss
5. High heat resistance coefficient, strong resistance to electric shock
6. Free from environmental interference and high reliability
7. Bus architecture is simple, layout is clear, installation is convenient, and maintenance workload is low.
Conventional rectangular bus has been unable to meet people's needs, Insulation aluminum tube busbar into the market, will continue to replace the rectangular bus.
