Cesar,

That first pic in the first row is a good example of the insulators

The steel frame work is a Buss.This allows them to branch off different lines in various directions .the buss work also has disconnects so they can turn off a particular circuit without interruption to the others.In other words one transformer would feed 3 or 4 -3 phase circuits a 3 phase circuit is Cross arm on top 3 wires on top one wire below those.
