The NEC doesn't apply to utility equipment, which the power pole is. 
Basically, the NEC's "domain" starts at the service entrance.

However...
I don't recall seeing a 1.5x clearance requirement in the NEC, either. 
Not that it isn't there, but I just don't remember seeing it.

The NEC does have rules about how high above the ground the feeder or a 
branch circuit has to be (10 ft over sidewalks, 12ft over driveways, etc.)


There's also the NESC (National Electrical Safety Code), which has rules 
about how high trees should be under power lines and such.

OSHA has rules about ladders, scaffolds, and the like, as well.
