Yep, there it  is.
I'm suggesting you use the higher voltage (24v is good) on the long cable
run
and add the small switching regulator at the point of the servo. Each servo
would have it's own regulator within a few inches of the servo.

All the above _is_ the "actual servo powering". Not the PWM data pulse.
