There are 3 answers for this:
1-its indicating the low flying aircrafts that there is a power transmission line.
2.its avoinding the collision of power transmission lines between one another.
3.its used for the purpose of creating a 'sag' in order to avoid voltage loss during transmission in over head lines.
mostly these are made up of non-conductive,light reflective type fibre.

They are made of fiber glass and they are areodynamic and keep the lines steady during a high wind. The lines won't whip back and forth with them on them.

They are made of glass fibre and are used make the power lines more visible to pilots.

usually markers so that low flying aircraft or large ground vehicles (like cranes) can easily spot and avoid hitting them

They are there to help airplanes see the lines so they don't fly into them.
