korkeajännitejohtimien

Korkeajännitejohtimien is a Finnish term that translates to "high-voltage conductors" in English. These are electrical wires designed to transmit electricity at very high voltage levels, typically ranging from tens of thousands to hundreds of thousands of volts. They are a critical component of the power grid, responsible for carrying electricity over long distances from power generation plants to substations where the voltage is reduced for distribution to consumers.

High-voltage conductors are usually made of aluminum or copper, often reinforced with steel for strength, especially in overhead lines. They are typically bare (uninsulated) in overhead transmission lines because the high voltage creates sufficient electrical insulation in the air. However, they are insulated when used in underground cables or within electrical equipment. The design and material of these conductors are chosen to minimize electrical resistance and energy loss during transmission.

The installation and maintenance of high-voltage conductors are subject to strict safety regulations due to the inherent dangers of high voltage. They are supported by large towers or poles for overhead lines and are often buried in conduits for underground systems. The efficient and reliable operation of high-voltage conductors is essential for the functioning of modern society, providing power for homes, industries, and infrastructure.
