Comparison of Advantages and Disadvantages between Copper Conductor Busbar and Aluminum Conductor Busbar
Advantages of Copper Conductor Safety Busbar:
1. Due to the use of T2 purple copper material for the conductor, the copper conductor busbar has good conductivity, low resistivity, low electrical loss for long-distance transmission. At the same time, the contact surface between the copper conductor busbar and the current collector is copper-to-copper, which has better electrical transmission performance than aluminum conductor.
2. Due to the properties of copper itself, the copper conductor busbar can be applied in special environments, such as workshops with water vapor, dust, corrosive gases, and other relatively harsh environments.
3. The accessories of the copper conductor busbar also use copper materials, which can also reduce electrical loss. The service life of copper conductor busbar in conventional indoor environments is about 10 years.
4. Since most copper materials in China are imported, and copper is more scarce than aluminum, the price of copper is higher than aluminum, about 3 to 4 times more expensive.
5. Since the copper conductor busbar is in direct contact with the current collector without a wear-resistant layer, its wear resistance is not as good as that of aluminum single-pole.
Advantages and Disadvantages of Aluminum Conductor Safety Busbar:
1. The conductor of the aluminum single-pole safety busbar adopts 6101A professional conductive profile, which contains copper elements, providing higher conductivity and lower resistivity compared to other similar aluminum profiles. Of course, compared to copper conductors, aluminum has higher resistance than copper.
2. The slot of the aluminum single-pole safety busbar is embedded with 304 stainless steel strip, which can improve the wear resistance of the busbar, better than copper. At the same time, the 304 stainless steel strip can also enhance the mechanical properties of the busbar conductor.
3. The price of aluminum conductor safety busbar is lower than that of copper conductor. In conventional workshops, using aluminum single-pole safety busbar can reduce costs for enterprises and improve the utilization efficiency of the busbar. The service life of aluminum conductor busbar in conventional workshops is about 10 to 15 years.
4. The shells of copper conductor safety busbar and aluminum conductor safety busbar use the same material, which has flame-retardant properties, ensuring their safe use.
Application Suggestions:
1. If applied in conventional workshops (without corrosive gases and water vapor), Dema Electric recommends the user to adopt aluminum conductor busbar.
2. For workshops with a length exceeding 150 meters, such as a 260-meter long workshop, with three-wire system installation, it is recommended to add 6 temperature compensators to prevent deformation of the busbar due to thermal expansion and cold contraction caused by indoor temperature differences.
