korkeajännitevastustyyppejä

Korkeajänniteverkko refers to the high-voltage electricity transmission network in Finland. This network is essential for transporting large amounts of electricity from power generation facilities to substations, from where it is then distributed to consumers at lower voltages. The Finnish high-voltage network operates at several voltage levels, with the highest typically being 400 kilovolts (kV) and 220 kV. These lines are crucial for ensuring a stable and reliable electricity supply across the country, covering long distances and connecting major population centers and industrial areas.

The primary operator of the Finnish high-voltage transmission grid is Fingrid Oyj. They are responsible for the planning, construction, operation, and maintenance of this critical infrastructure. Fingrid's role extends to ensuring the secure and efficient functioning of the entire electricity market, including managing the flow of electricity and maintaining the balance between supply and demand. The high-voltage lines are characterized by their tall pylons and long spans, traversing various landscapes to connect power plants, such as nuclear or large thermal power stations, with the national grid. The integrity and modernization of the korkeajänniteverkko are vital for Finland's energy security and its transition towards renewable energy sources, as these often require efficient long-distance transmission.
