ilmajohtoverko

Ilmajohtoverkko refers to an overhead power line network used for transmitting and distributing electricity. These networks consist of a system of cables, poles, insulators, and other supporting structures that carry electrical current through the air from generating stations to consumers. The cables are typically made of conductive materials like aluminum or copper, and they are supported at intervals by poles or towers. Insulators are used to prevent the electricity from flowing into the supporting structures and to the ground.

Overhead power lines are a common and cost-effective method for electricity distribution, especially in rural and less densely populated areas. They are generally easier to install and maintain compared to underground cables. However, they are also more susceptible to damage from weather events such as storms, lightning, and falling trees. Power outages can occur when these lines are compromised. The design and construction of ilmajohtoverkko systems adhere to strict safety regulations to minimize risks to people and property. Maintenance involves regular inspections, repairs, and upgrades to ensure reliability and safety of the electricity supply.
