1.Aluminum Aluminium Seamless Bus Tube Pipe
Aluminum Aluminium Seamless Bus Tube Pipe refers to the seamless aluminium Tube Pipe which is extruded from pure aluminium or aluminium alloy to be hollow along its longitudinal length. The Aluminum Aluminium Seamless Bus Tube Pipe has uniform texture and better performance than the seamed Tube Pipe, so the Aluminum Aluminium Seamless Bus Tube Pipe has better mechanical and electrical properties than the ordinary aluminium alloy bus tube.
The alloy commonly used for Seamless Bus Tube Pipe is 6063, 6061 and 6101. The 6063 alloy is widely used in outdoor high-voltage substation Bus Tube Pipe due to its excellent mechanical and electrical properties. In the case of high strength and low conductivity, the 6061 aluminum alloy Bus Tube Pipe is used. In the case of high electrical conductivity and minimum mechanical loss, 6101 alloy Bus Tube Pipe is used.
 
1) Implementation standard: GB/T27676-2011 aluminum and aluminum alloy bus tube pipe conductor or ASTM B 317M-07
2) Product Alloy: 6063,6101,6061
3) Product Temper: T6 
4) The product is hollow tubular structure with glossy surface, beautiful appearance and uniform size.
5)The outer diameter is from 60mm to 450mm.
6)The Wall thickness from 3mm to 15mm.
7) The length of a single bus tube pipe conductor can reach up to 15 meters.

4.The main performance of Aluminum Aluminium Seamless Bus Tube Pipe as follows:
1)  Aluminum Aluminium Seamless Bus Tube Pipe  adopts hot-top casting seamless pipe tube etc a series of advanced technology, with smooth surface, high dimensional accuracy, high tensile strength, not easy to discharge and deformation, low power loss, equivalent to 40% of rectangular bus and cable;
2) Aluminum Aluminium Seamless Bus Tube Pipe has excellent machining, welding, conducting and heat resistance. The products were certified by the science and technology department and reached the international advanced level.
3) The convection heat dissipation condition is good, the temperature rise is low, the loss is small, the electrical conductivity is strong, the carrying capacity is big.
4) The installation area is small, and the combined busbar is the 1/3 of the soft conductor installation area.
5) The inner grain structure is compact, the corrosion resistance is strong,and it is not easy to ice coating, the ability to resist disasters is strong, and the service life is long.
6) Easy installation, beautiful appearance, safe, stable and reliable operation, convenient for maintenance.
5.The usage of Aluminum Aluminium Seamless Bus Tube Pipe:
Aluminum Aluminium Seamless Bus Tube Pipe is mainly used as overcurrent conductor in power construction projects, such as conductor connection between power grid transmission conductor and transformer substation, jumper in transmission line, connection conductor in power equipment and high current DC ice melting device,It is a new conductor to replace the traditional rectangular, groove, bar-shaped bus and soft conductor.
It is one of the key equipment (materials) in power transmission and transformation system, and plays a vital role in the safe and reliable operation of power transmission and transformation system and power equipment.
