3 phases and a neutral pass over the pole
1 phase and 1 neutral pass over the pole while 1 phase and 1 neutral dead-end at the pole
Though it's grainy, you can see 3 phases and a neutral dead-ending at the pole
1 phase and 1 neutral pass this pole at an angle
1 phase and 1 neutral dead-end at the pole. You'll get some weird variation of the spec with poles like this. "A5-1S" for example.
1 phase and 1 neutral pass over the pole
It's likely the neutral is connected to the pole below the picture. There are 2 phases passing over the pole.
This one is tricky. One could assume this is some variation of a C5 (amongst other things). There are 3 phases and 1 neutral dead-ending at the pole on the left. It seems they slack over to the other pole to continue the line. There's not a good way of knowing why the poles are framed like this without seeing the surrounding area.
We can see 3 fuses hanging from the crossarm, so we know there are 3 phases and we can assume there is a neutral below. The lines dead-end on opposite sides of the pole with no angle.
