Attached below is an image of a Power transmission pole. What I am interested in is the cylindrical shaped objects attached to the transmission tower.
Some other observations and relevant information:
- These objects are not present in every tower but on one in every few towers or so.
- These towers are from a mixed Residential and commercial neighborhood
- The towers in question are in Japan. I have not observed these cylindrical objects on similarly sized transmission towers in my Home country
A less relevant observation is that even though these are overhead transmission lines, they are insulated, perhaps because of the proximity of the houses and buildings to the towers
EDIT: There is a similar question linked here, however, this picture has both a single phase and larger 3 phase transformer while this earlier question had only a single phase one. Further, the question uses different terminology to describe the transformer (cylinder vs canister)
