High-voltage conductor used to carry electrical power from one place to another.
a conductor for transmitting electrical or optical signals or electric power
a distributed-parameter network where voltages and currents can vary in both magnitude and phase over its length
a high-voltage overhead power line - the lines operated by National Grid
a medium through which energy and signals are transmitted
an electrically suitable structure used to guide the signal energy between two points
a pair a conducting wires held apart by an insulator or dielectric
a pair of parallel conductors exhibiting certain characteristics due to distributed capacitance and inductance along its length
a sub-category of waveguides that uses some physical configuration of metal and/or dielectrics to direct a signal along the desired path
A power line carrying high-voltage electricity between regions. Most transmission lines are built on steel towers and operate at voltages between 60 and 765 kV.
Power line used to efficiently carry electric current long distances from a power generation source to a substation. These lines carry higher voltages. Some common transmissions lines in northern New Mexico are 69 kV, 115 kV and 345 kV lines. See Distribution line.
A structure that guides electromagnetic energy.
A pipeline, other than a gathering or distribution line, that transports gas from a gathering or storage facility to a distribution center or storage operates at a hoop stress of 20 percent or more of the specified minimum yield stress of the pipe, or transports gas within a storage field. (See 49 Code of Federal Regulations 192)
Pipeline transporting natural gas from principal supply areas to distribution centers, large volume customers or other transmission lines. Transmission lines generally have a linear configuration, may be quite large in diameter, operate at relatively high pressure, and traverse long distances.
A pair of conductors separated by a dielectric.
The material medium or structure that forms all or part of a path from one place to another for directing the transmission of energy, such as electric currents, magnetic fields, acoustic waves, or electromagnetic waves.
A device designed to guide electrical or electromagnetic energy from one point to another.
A signal-carrying circuit with controlled electrical characteristics used to transmit high- Frequency or narrow-pulse signals.
A path from one place to another, used for directing the transmission of electromagnetic energy.
A signal-carrying circuit composed of conductors and dielectric material with controlled electrical characteristics used for the transmission of highfrequency of narrow pulse type signals.
Facility for transmitting electrical energy at high voltage from one point to another point. Transmission line voltages are normally 115 kilovolt or larger.
The poles, towers and lines used to move bulk electricity from a generating plant to a substation.
Any high-voltage line that operates at 69,000 volts or more.
A signal carrying composed of conductors and dielectric material with controlled electrical characteristics used for the transmission of high frequency or narrow- pulse type signals.
A power line that carries power from the generating plant to the substation.
Any line operating at 69,000 or more volts.
An arrangement of two or more conductors, a coaxial cable, or a waveguide used to transfer signal energy from one location to another.
A line used for bulk transfer of electricity between a generating plant or receiving point and major substations or delivery points.
The connecting link allowing the radio frequency energy generated by the radio to be delivered to the antenna. (Coaxial cable, microstrip or coplanar lines in our industry.)
A conductor that is configured to have a specific impedance value. See microstripline and stripline.
A connection over which data devices communicate. There are five main types of transmission lines: circuits, channels, lines, trunks, and virtual circuits.
Structures an conductors that carry bulk supplies of electrical energy from power-generating units.
Any conductor that carries energy from the source to its load.
Conducting line used to transmit signal energy between two points.
A transmission line is the material medium or structure that forms all or part of a path from one place to another for directing the transmission of energy, such as electromagnetic waves or acoustic waves, as well as electric power transmission. Components of transmission lines include wires, coaxial cables, dielectric slabs, optical fibres, electric power lines, and waveguides.
