Question

What are the three types of transmission lines?

Answer 1

The three main types of transmission lines are:

1. Overhead Transmission Lines:
   

   - These are the most common type of transmission lines, especially for long-distance power distribution.
   - They consist of conductors (wires) supported by tall poles or towers.
   - They are exposed to the environment, making them more vulnerable to weather conditions but cheaper to install and maintain.

1. Underground Transmission Lines:
   

   - These lines are buried underground and are used in areas where overhead lines are impractical or unsightly.
   - They are more expensive to install than overhead lines but are protected from weather conditions and reduce visual pollution.

1. Submarine Transmission Lines:
   

   - These lines are laid on the seabed or under the sea to connect power between land masses or offshore platforms.
   - They are used in cases where traditional land-based transmission lines cannot be used, like when crossing large bodies of water.

Each of these types serves a different purpose depending on the location, cost, and other factors.
