Advantages of tubular aluminum buspipe

Tubular aluminum buspipe offers several advantages over flat conductive aluminum bars. Its shape reduces the corona discharge onset voltage, enhancing stability, while its natural tubular structure provides superior heat dissipation, ensuring stable system operation. Additionally, tubular designs exhibit lower skin effect, resulting in uniform current density distribution, reducing power loss, and increasing transmission efficiency.

The inherent rigidity of the tubular shape in all directions enables it to withstand wind and ice loads, as well as short-circuit forces, making it particularly suitable for outdoor substations and switch structures that require large-span supports.

6101 round tubular aluminum buspipe

Round tubular buspipe, due to its low skin effect ratio, is the most effective ac bus conductor shape. Although its smaller heat dissipation surface area limits current ratings, the seamless tubular design makes it ideal for heavy-duty generators and switch busbars at central stations. The high-conductivity 1350 alloy and high-strength 6101 alloy are excellent options for this application.

6101 square tubular aluminum buspipe

Square tubular buspipe also features a low skin effect ratio and is easy to mount on base insulators. Its flat sides facilitate the connection of branch terminals, making it commonly used in generator and station busbars. Alloys like 6101 t61 and 6063 t6 are typically used, with staggered ventilation holes on the top and bottom surfaces for enhanced cooling.


Technical requirements for mastar metal aluminum tubular buspipe

Mastar metal aluminum tubular buspipe is manufactured using advanced hot-top casting, seamless tube processing, and tmtp heat treatment technology, ensuring smooth surfaces, high dimensional accuracy, strong tensile strength, and robust resistance to discharge and deformation. These features provide excellent thermal convection cooling, low temperature rise, minimal loss, high conductivity, and large current-carrying capacity in power systems. Specific technical requirements include:

  • Pipes must have flat ends, perpendicular to the axis.
  • The permissible length deviation range is +15mm to +25mm.
  • Straightening spiral marks are allowed as long as they do not affect the outer diameter, with a maximum depth of 0.5mm.
  • The buspipe's bend must satisfy m/l < 2.0 mm.
  • The gap between the buspipe and the liner must not exceed 0.5mm, ensuring installation requirements are met.
  • The surface should be smooth and free of cracks, wrinkles, inclusions, deformation, and twisting.
  • The elastic modulus must be controlled to ensure that the deflection after installation remains within the specified range.

6063 T6 Fair Fair Excellent Excellent Excellent Excellent
1350 H111 Excellent Poor Excellent Excellent Excellent -

6101 offers higher mechanical strength than 6063, making it suitable for applications requiring greater mechanical stress resistance. While its conductivity is slightly lower than that of 1350, it still provides excellent electrical performance, ideal for high-efficiency power transmission and distribution systems.

6063 is easy to extrude and has good mechanical properties. Although its conductivity is slightly lower, its excellent workability makes it perfect for complex substation piping layouts and bus system installations.

1350, being pure aluminum, boasts extremely high conductivity, making it the best choice for applications demanding very high electrical conductivity, particularly in power transmission and distribution systems where maximizing current transmission efficiency is critical.

Each alloy and temper offers unique advantages and is suited to specific applications. Choosing the right product should depend on the specific project requirements and budget.

The difference between Aluminum bus pipe and aluminum bus tube

Bus pipe is manufactured to a "nominal" (not actual) diameter. The wall thickness is described by a "schedule." I.e. 4" sch40. Bus

Tube is a round hollow material manufactured to a specific outside diameter (o.d.) And wall thickness. It is produced to meet the end users requirements.

Factors to consider when choosing bus conductors

When selecting bus conductors, it's important to consider factors such as the type of current, current-carrying capacity, frequency, operating voltage, voltage drop, short-circuit current, available space, taps, and connections. For high-current applications, current density is critical, while outdoor substations must account for weather conditions. Industrial design should focus on temperature rise, current capacity, and power loss.

Seamless vs. Structural pipes in substation construction

In substation construction, seamless pipes are recommended because they lack welded seams, which prevents splitting under repeated bending. Structural pipes, which have welded seams, are only suitable for structural applications and are not appropriate for handling fluid pressure or repeated bending.

Maximum buspipe length offered by Mastar Metal

Mastar metal typically offers buspipes ranging from 3 meters to 15 meters (10 to 50 feet) in length. Due to transportation limitations, the maximum length available is 15 meters (50 feet). For detailed information on buspipe lengths, please contact mastar metal.

How to order Mastar Metal aluminum buspipe

To order mastar metal aluminum buspipe, first determine the required outer diameter, wall thickness, alloy, and temper based on your project needs. Then, confirm the specific product performance parameters, such as conductivity, tensile strength, and yield strength. Finally, select the appropriate packaging method, and finalize payment terms and delivery dates.
