What Is The Difference Between Copper Busbar And Traditional Cable?

As traditional cables for transmission lines, they are no longer able to meet the relevant requirements in high current transmission systems. Copper bars are a high current conductive product with high current carrying capacity, and have replaced traditional cables as conductive connecting materials in many applications. Many friends are curious about the difference between copper busbar and traditional cables. Now, copper busbar manufacturer Paige Rui shares a few points with you.

In terms of current carrying capacity: copper bars have high current density and low resistance. Under the same current carrying capacity, the cable area requirement is larger than that of copper bars, which not only increases voltage drop, but also easily generates heat, resulting in significant energy loss and aging of the line. The current carrying capacity of traditional cables is not as good as that of copper bars, and the unique material and structure of copper bars determine their strong current carrying capacity.

From a structural perspective: cables are flexible and can be bent; The busbar is rigid and made of relatively hard material, which cannot be easily bent. Therefore, a specialized bending connection needs to be designed.

From the perspective of production technology: bus bar, also known as busbar, is a connecting busbar connected by multiple devices in parallel branches on a common path; Traditional cables are made from one or more insulated conductors. The installation and production of cables are quite complicated, and each electrical equipment needs to be independently wired and wired. The installation of copper busbar is more flexible and convenient, and is not prone to errors. One copper busbar can supply electricity to multiple devices at the same time.

From the perspective of function: the function of copper busbar is to collect and distribute current, so the current flowing through the busbar is relatively large. Therefore, it is necessary for the busbar to have a large carrying capacity, and there are also requirements for the cross-sectional area of the busbar. The function of cables is to transmit and distribute electricity. Cables have a strong ability to transmit current and are mainly used in three-phase circuits, so the vast majority of cable structures are designed with three or more cores.
