Most extended length power lines don’t use insulation within the conductors themselves. Insulating in this manner must be so thick that it wouldn’t be cost effective. In its place, most of the insulation originates from air gaps, or simply spacing everything much enough aside. Transmission towers and pylons are truly tall to stop any individual or any automobile on the bottom from inadvertently acquiring shut enough to conductors to make an arc. Bulk energy is transmitted in three phases, And that's why you’ll see most transmission conductors in groups of three. Every single stage is spaced much adequate from the other two to avoid arcing involving the phases. The conductors are linked to Each and every tower by way of prolonged insulators to keep enough distance concerning energized lines and grounded pylons.
