õhuliin

Õhuliin is an Estonian term referring to an overhead power line. These lines are a common method for transmitting and distributing electrical energy from power plants to consumers. They consist of electrical conductors supported by poles or towers, which are typically made of wood, steel, or concrete. The conductors are usually made of aluminum or copper and are insulated to prevent short circuits.

Overhead power lines are a cost-effective solution for electricity transmission, especially in rural areas where underground cabling would be prohibitively expensive. However, they are susceptible to damage from weather conditions such as strong winds, ice accumulation, and lightning strikes. Wildlife, particularly birds, can also pose a risk to overhead lines, sometimes leading to power outages or bird electrocution.

Maintenance of õhuliin is crucial for ensuring a reliable power supply. This involves regular inspections, repairs, and vegetation management to keep trees and branches away from the lines. In recent years, there has been a trend towards burying power lines underground in urban areas to improve aesthetics, reduce vulnerability to weather, and minimize bird-related incidents, though this is a more expensive undertaking. The design and placement of õhuliin are subject to various regulations and standards to ensure safety and operational efficiency.
