távvezeték

Távvezeték, also known as a transmission line, is a type of electrical conductor used to carry alternating current (AC) over long distances. It consists of two or more parallel conductors, typically wires or cables, which are insulated from each other and from the ground. The primary purpose of a távvezeték is to minimize power loss and maintain the integrity of the electrical signal over long distances.

The design of a távvezeték is crucial for efficient power transmission. It includes several key components: the conductors, which are usually made of aluminum or copper; the insulation, which prevents electrical arcing and short circuits; and the protective sheath, which provides mechanical protection and insulation from the environment. The spacing between the conductors is carefully calculated to ensure optimal performance and safety.

Távvezetéks are used in various applications, including power transmission between power plants and substations, and between substations and distribution networks. They are also used in telecommunications to transmit radio frequency signals. The choice of távvezeték depends on factors such as the voltage level, the distance to be covered, and the environmental conditions.

Maintaining a távvezeték is essential for its longevity and performance. Regular inspections, cleaning, and repairs are necessary to prevent faults and ensure safe and reliable operation. Advances in technology have led to the development of more efficient and reliable távvezetéks, including high-voltage direct current (HVDC) transmission lines and composite insulated conductors.
