1. Transmission towers: These are tall structures that support the overhead transmission lines and carry the weight of the conductors. They are typically made of steel or concrete and are spaced at regular intervals along the transmission line route.
2. Insulators: Insulators are used to support the conductors and prevent them from coming into contact with the transmission towers or other structures. They are typically made of porcelain or glass and are designed to withstand high voltages.
3. Crossarms: Crossarms are horizontal structures attached to the transmission towers that support the conductors. They are typically made of wood or steel and are designed to distribute the weight of the conductors evenly.
4. Guy wires: Guy wires are used to provide additional support to transmission towers, especially in areas with high winds or other environmental factors that could cause the towers to sway or lean. They are typically made of steel and are anchored to the ground to provide stability.
5. Grounding systems: Grounding systems are used to protect the transmission line from lightning strikes and other electrical disturbances. They provide a path for electrical current to safely dissipate into the ground, reducing the risk of damage to the transmission line or surrounding structures.
6. Spacer dampers: Spacer dampers are devices that are attached to the conductors to prevent them from vibrating or oscillating in high winds. They help to reduce the risk of conductor fatigue and extend the lifespan of the transmission line.
7. Lightning arrestors: Lightning arrestors are devices that are installed on transmission towers to protect the line from lightning strikes. They divert the electrical current from the lightning strike away from the transmission line, reducing the risk of damage to the conductors or other components.
