Definition

1. Noun:
   • A conductor for transmitting electrical or optical signals or electric power: A physical structure, such as a wire, cable, or waveguide, designed to carry energy efficiently from one point to another with minimal loss.

Usage Examples

• Noun:
  • The new transmission line will carry electricity from the solar farm to the city.
  • Engineers are repairing the damaged optical transmission line that carries internet data.
  • High-voltage transmission lines are a common sight across the countryside.

Advanced Usage

• "to be strung along transmission lines": to be suspended or hung on the cables used for power transmission.

  • The new fiber-optic cables were strung along the existing transmission line towers.

• "transmission line theory": the electrical engineering principles governing the propagation of signals along conductors.

  • Understanding transmission line theory is essential for designing high-speed communication circuits.

Variants and Related Words

• Power line (n): A type of transmission line specifically for carrying electrical power.

  • The storm knocked down several power lines.

• Waveguide (n): A hollow metallic conductor used as a transmission line for microwaves or radio waves.

  • The radar system uses a waveguide to direct the signal to the antenna.

• Feed line (n): A transmission line that connects a radio transmitter or receiver to its antenna.

  • The technician checked the feed line for any impedance mismatches.

Synonyms

• Conductor: A material or object that allows the flow of electrical current or transmits energy.
• Power cable: An insulated assembly of conductors for transmitting electrical power.

Related Phrases

• Overhead transmission line: A transmission line suspended on towers or poles above the ground.

  • Most long-distance electricity is carried by overhead transmission lines.

• Underground transmission line: A transmission line buried beneath the earth's surface.

  • The downtown area uses underground transmission lines for aesthetic and safety reasons.
