Bundled Conductors and Composite Conductors Difference

Composite Conductors:

In Composite conductors sub conductors touch each other. Composite conductors are typically stranded conductors. In Composite conductors different elements are used (In ACSR conductors aluminum has the properties of light weight, good conductivity and rutlessness and steel has the property of high tensile strength). Composite conductors are employed as they are flexible compared to solid conductor. Composite conductors reduce proximity effect and also reduces skin effect up to certain extent.

Bundled Conductors:

Bundled conductors are employed in Extra High Voltage (EHV) transmission as at higher voltages corona effect is significant. In bundled conductors sub conductors are placed as certain distance throughout the transmission lines. This reduces the corona discharge loss and interference with the communication lines nearby.
