Tehojohtojen
Tehojohtojen, often translated as power lines or transmission lines, are essential components of electrical power systems. They are designed to transmit electrical energy from power generation plants to substations and then to consumers. These lines typically consist of conductors, insulators, and supporting structures. The conductors are usually made of highly conductive materials like aluminum or copper, often reinforced with steel to increase strength. Insulators are crucial for preventing electrical current from flowing into the supporting structures and the ground, thus ensuring safety and efficiency. Common insulating materials include porcelain, glass, or composite polymers.
The supporting structures for tehojohtojen can vary significantly depending on factors such as voltage, terrain, and
