Question

Question: For EHV lines, a common practice of conductor bundling is used. Why?

Short answer

Answer

Hence the common practice for EHV line is bundling.

Step-by-step solution

Concept of bundle conductor.

When two or more two stranded conductors are used as one per phase, then it is known as the bundle conductor.Conductors are keyed together to increase the current carrying capacity of the conductor. Conductor Bundle conductor used is system where voltage is or more than .

Reason to use the conductor bundling.

The bundle conductor reduces the electrical field strength at the conductor's surface, which minimizes the corona losses and increases the Geometric mean radius of the conductor. Therefore, inductance per phase reduces, and capacitance per phase increases.

The bundle conductor also reduces power loss, communication interference, and diminished audible noise.
