Advantages of 1070 Aluminum Busbar Compared to Copper
| Advantage | Description |
| Cost-effective: Lower material and installation costs | 1070 Aluminum Busbar offers significant cost advantages compared to copper. The price of aluminum is generally lower than copper, so using aluminum busbars can effectively reduce initial procurement costs. Additionally, the installation costs of 1070 aluminum busbars are lower, as aluminum has a lower density than copper, making transportation and handling more convenient. With both material and installation cost savings, 1070 aluminum busbars provide a more cost-effective solution for power systems. |
| Lightweight: Reduces structural support requirements | Due to its lower density, 1070 Aluminum Busbar is much lighter than copper. This lightweight feature reduces the need for supporting structures during installation, thereby lowering the cost and difficulty of the supporting infrastructure. Especially in large power systems, using aluminum busbars can significantly reduce the overall weight burden, simplify structural design, and make transportation and installation more efficient. |
| Abundant: Readily available and sustainable choice | 1070 Aluminum Busbar is a very abundant resource, with a relatively stable and widely available supply of aluminum, making this material easy to source in the market. Aluminum is also a sustainable material, as its recycling process is simple and efficient, meeting green environmental requirements. The high recycling rate of aluminum allows it to be remelted and processed after use, further reducing the demand for new resources. |
1070 Aluminum Busbar Compared to 1350 Aluminum
The conductivity of 1070 Aluminum Busbar is slightly lower than that of 1350 aluminum, but it remains a highly suitable choice, especially for fixed installations. While the conductivity of 1350 aluminum is approximately 63% IACS, which is commonly used for overhead lines and applications requiring higher conductivity, 1070 aluminum busbars offer an excellent cost-performance ratio, making them an economical choice for fixed installations.
Although 1070 aluminum busbars have slightly lower conductivity than 1350 aluminum, their lower cost makes them very popular in many fixed installation scenarios. Especially in environments where the conductivity requirements are not extremely stringent, 1070 aluminum can provide sufficient current-carrying capacity while significantly reducing material procurement and installation costs. Due to its good mechanical strength and durability, 1070 aluminum busbars remain stable during long-term use, making them an economical and reliable solution.
Therefore, 1070 aluminum busbars not only offer cost efficiency in applications but also meet most fixed installation needs, especially when extremely high conductivity is not required, making them an ideal alternative to 1350 aluminum.
Advantages and Limitations of 1070 Aluminum Busbar
The 1070 aluminum busbar has significant advantages in terms of lightweight construction, conductivity, and cost-effectiveness, but it also has certain limitations regarding strength and connection technologies.
