The appearance of aluminum alloy tube bus is more beautiful, and uniform size, its structure is hollow tube shape, the longest single length of aluminum tube bus is generally up to 15 meters.Of course, the appearance of the aluminum alloy tube bus is also a certain requirement, in the appearance of the requirements of aluminum alloy tube bus surface to be smooth and smooth, so qualified aluminum tube bus is not there will be cracks, folds and inclusions or deformation distortion and other phenomena.The orifice must also be flat and perpendicular to the axis.Actually, also be to allow aluminium alloy tube bus to have a few small threads to appear, but cannot affect outside diameter dimension, it is to point to straightening the existence of helical mark commonly, but the depth of helical mark cannot exceed 0.5mm.These reflect the appearance of the aluminum alloy tube bus bar requirements are very high.
2. Performance of 3A21 aluminum alloy tube bus
The practice shows that the aluminum alloy tube bus is not only a new type of energy-saving conductive material, but also can replace the traditional steel-cored aluminum wire, trough and rectangular aluminum bus.Its surface is very smooth, and its dimensional precision is very high, at the same time, its tensile strength is very large, so, in normal circumstances, it will not produce deformation and discharge.In addition, its convective heat dissipation conditions are also good, the loss is also small, it can carry a large amount of current, and its conductive ability is very strong.Although its function is much and performance is strong, but the space area that it installs place to need is small, install rise very convenient also.It has to be mentioned that the heat resistance of aluminum alloy tube bus is very high, and it has very strong mechanical strength at very high temperature. Therefore, it can improve the safety and reliability of power transmission and transformation system.Its life is relatively long, disaster resistance is also very strong, but also easy to test and maintenance.
3. Use of 3A21 aluminum alloy tube bus
Mention the use of aluminum alloy tube bus, we have to mention that it is one of the leading products of the bus oh!At the same time, it is also one of the key equipment materials in the power transmission and transformation system!Moreover, it also plays a very important role in the safe operation of power transmission and transformation system.In general, aluminum alloy tube busbar is mainly used in power construction projects, usually used to connect power grid transmission wires and transformer substations, so it is also the connection conductor in power equipment, it can also be in the large current DC ice melting device as the over-current conductor.It can be seen that its role is really not small!Because of this, it is regarded as a new kind of conductor, which can not only replace the traditional rectangular, groove and bar busbar, but also replace the soft conductor to work.
