Professional Answer: The primary components of a typical utility pole, which serves as a line support, are:

1. The pole itself: The vertical structure made of wood, concrete, or steel.

2. Cross-arms: The horizontal beams that attach to the pole to support the other components.

3. Insulators: Mounted on the cross-arms, these are where the conductors are attached.

4. Conductors: The wires that carry the electricity.

5. Ground wire/lightning arrester: A wire running down the pole that is connected to the ground to protect the line from lightning strikes.
