In simple words, a **transmission line** is used to **carry electrical power** from one place to another—usually from power stations (where electricity is generated) to homes, factories, and cities.
Here’s **what is in a transmission line**:
---
### 1. **Conductors (Wires)**
* These are the **actual wires** that carry electricity.
* Usually made of **aluminum** or **copper** because they are good conductors.
* In high voltage lines, they are often **stranded** (many small wires twisted together) for strength and flexibility.
---
### 2. **Insulators**
* These are materials that **do not conduct electricity**.
* They **hold the conductors** and **prevent electricity from leaking** to the poles or towers.
* Made of **ceramic, glass**, or **polymer**.
---
### 3. **Towers or Poles**
* These **support the conductors** and **keep them high above the ground**.
* Can be **steel towers**, **wooden poles**, or **concrete poles**.
* Keep the lines safe from people and trees.
---
### 4. **Ground Wire (Earth Wire)**
* A **wire at the top** of the tower used for **lightning protection**.
* It carries lightning to the ground and **protects the transmission line**.
---
### 5. **Spacers and Dampers**
* **Spacers** keep wires apart, so they don’t touch each other.
* **Dampers** reduce vibration due to wind, preventing damage.
---
### 6. **Electrical Power (Inside the wires)**
* What’s actually **flowing inside the conductor** is **alternating current (AC)** electricity.
* The voltage is usually very **high** (like 132 kV, 220 kV, 400 kV) to reduce losses during long-distance transmission.
