Cable and telephone lines are located further down the pole and are directly attached to power poles without insulators. Electric lines carry high voltages and are always placed at the top of utility poles. Telephone lines and cable lines are placed lower on the poles.
Why are there 3 power lines?
Because they carry 3-phase alternating current. When there are just 3 cables, the circuit is closed by ground. When there are 6 cables, it is a double-circuit power line. When there is a 4th cable, that is the ground cable and it is above the others, to protect them from lightning.
