insulated cable installed on poles via a steel messenger cable for the purpose of delivering power at distribution voltage levels.

a unit of measure for the flow of electricity. Often referred to as load.

a substation that reduces voltage from transmission levels to distribution levels. e.g. from 138,000 volts to 13,000 volts.

an overhead distribution system comprised of wire, transformers, switches, and vacuum reclosers installed on poles. An auto-loop will automatically isolate a fault on open wire, reducing the amount of customers interrupted.

a switch that automatically disconnects power to a circuit in the event of an electrical fault condition. May also be operated manually to disconnect power.

an electrical fault caused by the breakdown of the insulation on cable.

a large rigid conductor, usually constructed of copper, used for delivering power.

an insulated fitting for carrying a conductor through a metal enclosure of electrical equipment such as transformers or capacitors.

an insulated conductor that can be installed either overhead or underground.

a device which helps to improve the efficiency of transmission and distribution circuits by reducing power losses.
