OverviewOverhead lines (transportation)ConstructionClassification by operating voltageStructuresInsulatorsConductorsCompact transmission lines
Overhead lines or overhead wires are used to transmit electrical energy to trams, trolleybuses or trains. Overhead line is designed on the principle of one or more overhead wires situated over rail tracks. Feeder stations at regular intervals along the overhead line supply power from the high-voltage grid. For some cases low-frequency AC is used, and distributed by a special traction current network.
Decoding the Power Pole: Residential Electrical Service
Often, there will be three cables, known as a triplex, running from the transformer to an access point on your home or business. Within the triplex are two insulated, or hot, wires and a bare neutral wire.

A Field Guide To Transmission Lines
Transmission lines are always built with sets of three conductors with an optional small wire or two at the top of the structure to serve as lightning protection.
Understanding Electric Distribution Pole Anatomy
The thick bundle of cables lower on the pole, and the many small wires from them are for telephone and cable TV. The boxes on hte pole just below those wires are a micro cell phone repeater.
Types of Electrical Wires and Cables
Choosing the right types of cables and electrical wires is crucial for all of your home improvement projects. Our guide will help you unravel the options.
three phase
As far as I know, the wires on top are not neutral, they are for distributing lightning strikes to multiple towers. Most long distance high voltage transmission is done in 3-phase Delta
Types of Electrical Wires and Cables
A wire is made of a single electrical conductor while a cable is a group or bundle of multiple wires inside a common sheathing. Both of them are used for carrying electrical current.
