Overhead lines are composed of conductors, poles, insulators, cross arms, line fittings and other parts. Some poles are equipped with cables, sheet piles, etc. .
Overhead lines are mainly composed of conductors, towers, insulators, cross arms, hardware and foundations.
1. Conductors are the main component of overhead lines and are responsible for transmitting electrical energy. Usually made of metal materials with good electrical conductivity, such as copper and aluminum. Wires are usually mounted on poles or towers to form transmission lines.
2. A tower is a structure that supports conductors, usually made of steel or concrete. The height and shape of the poles vary according to the voltage of the line and terrain conditions.
3. Insulators are devices used to secure wires and prevent current leakage. They are usually made of ceramic or glass and have high insulating properties.
4. Cross arms are metal components used to support conductors, usually made of angle steel or steel pipes. Cross arms can increase the stability of the wire and ensure smooth current transmission.
5. Fittings are metal accessories used to connect and fix wires. They include bolts, nuts, washers, terminal blocks, etc. of various shapes and sizes.
6. The foundation is the concrete structure used to support the tower. Depending on the terrain conditions, the form and size of the foundation will vary.
These components work together to ensure safe and stable operation of overhead lines. Overhead lines play an important role in the power system, providing people with electrical services and promoting economic development and daily life.
