õhuliini

õhuliini is an Estonian term that translates to "overhead line" or "overhead power line." It refers to a system of electrical conductors suspended on poles or towers to transmit electricity from generating stations to substations and then to consumers. These lines are a crucial component of the electrical grid, enabling the efficient transport of large amounts of power over long distances.

The construction of õhuliini involves various components, including high-voltage cables, insulators to prevent current leakage, and supporting structures like wooden poles or steel towers. The height and type of support structure depend on factors such as the voltage of the line, the terrain, and environmental conditions. Insulators are typically made of ceramic or glass and are designed to withstand significant electrical and mechanical stress.

õhuliini are a cost-effective method for power transmission compared to underground cables, especially over vast areas. However, they are also susceptible to environmental factors such as storms, ice accumulation, and falling trees, which can lead to power outages. Maintenance and repair are essential to ensure the reliability and safety of the overhead line network. The design and operation of õhuliini are subject to strict regulations to minimize risks to the public and the environment. In urban areas, efforts are sometimes made to place power lines underground to improve aesthetics and reduce vulnerability to weather.
