An overhead power line is a structure used in electric power transmission and distribution to transmit electrical energy along large distances. It consists of one or more conductors (commonly multiples of three) suspended by towers or poles. Since the surrounding air provides good cooling, insulation along.
Towers for support of the lines are made of wood (as-grown or laminated), steel or aluminum (either lattice structures or tubular poles).
Structures for overhead lines take a variety of shapes depending on the type of line. Structures may be as simple as wooddirectly set in the earth, carrying one or more cross-arm.
The most common conductor in use for transmission today is(ACSR). Also seeing much use is all-aluminum-alloy conductor (AAAC). Aluminum is.
Low voltage overhead lines may use either bare conductors carried on glass or ceramic insulators or ansystem. The number of conductors may be anywhere between two (most likely a phase and neutral) up to as many as six (three phase.
Overhead power transmission lines are classified in the electrical power industry by the range of voltages:• Low voltage (LV) – less than 1000 volts, used for connection between a residential or small commercial customer and the utility.
must support the conductors and withstand both the normal operating voltage and surges due to switching and .Insulators are broadly classified as either pin-type.
A compact overhead transmission line requires a smaller right of way than a standard overhead powerline. Conductors must not get too close to each other. This can be achieved either by short span lengths and insulating crossbars, or by separating the.Electricity is generated at power plants and moves through a complex system, sometimes called the grid. The grid includes electricity substations, transformers, and power lines that connect electricity producers and consumers.
