ilmajohtoverkko

Ilmajohtoverkko, also known as an overhead power line network, refers to the system of electrical conductors suspended above the ground on poles or pylons. These networks are a common method for transmitting and distributing electrical power over varying distances. The conductors, typically made of aluminum or copper, are supported by insulators to prevent the flow of electricity to the supporting structures.

The design and construction of ilmajohtoverkko take into account factors such as voltage levels, current capacity, environmental conditions, and safety regulations. Different types of poles and pylons are used depending on the terrain and the span between supports. The placement of these lines is crucial for efficient power delivery and minimizing potential hazards.

While ilmajohtoverkko are a cost-effective and relatively simple solution for power transmission, they are susceptible to damage from weather events like storms, ice accumulation, and high winds. They can also pose risks to aviation and wildlife. Consequently, regular maintenance and inspection are essential to ensure their reliability and safety. In some areas, underground cable networks are preferred to mitigate these issues, though they are generally more expensive to install.
