Answer 1

Bundling of conductors

Bundled conductors are those conductors that form from two or more stranded conductors, bundled together to get more current carrying capacity.

Advantages of Bundled Conductors:

Bundling of conductors leads to reduction in line inductance. By reducing the inductance, the power transfer capability of the transmission line increases.
The capacitance of the line increases. Now by decreasing inductance and increasing capacitance, the surge impedance loading of the line also increases.
Bundling conductors reduces corona loss by increasing the effective radius and spreading the electric field, thereby decreasing the electric field strength near the conductors and the likelihood of corona discharge.
As the bundled conductors have more effective surface area exposed to air, it has better and efficient cooling and hence better performance compared to a single conductor.
