Question

Comparison between bundled and stranded conductors

Answer 1

Since most long distance power lines in India are either 220 kV or 400 kV, avoidance of the occurrence of corona is desirable. The high voltage surface gradient is reduced considerably by having two or more conductors per phase in close proximity. This is called conductor bundling

Standard conductors. The conventional bare overhead conductor are characterized by the maximum operating temperature that is up to 80°C. These kinds of conductors are defined as standard because you can find them on international normative (EN50182, ASTM B231, B399, B232).
