What are bundled conductors?

Bundled conductors refer to a configuration where multiple conductors are grouped together and used within a single phase of an electrical system. This design is often employed to decrease the electrical resistance and improve the overall capacity of the transmission line, which is vital for efficient power delivery over long distances. By utilizing multiple conductors, the reactive power losses are reduced, and the system's thermal performance is enhanced.

In addition to improving performance, the use of bundled conductors can also help mitigate issues related to electrical fields and reduce the impact of corona discharge, which can occur with higher voltages.

This configuration supports better load distribution and can result in a smaller effective diameter, which is beneficial in terms of wind loading and ice accumulation impacts. Thus, the concept of bundled conductors is integral in modern electric transmission systems, optimizing their capabilities and reliability.
