Question

why some of the buildings do not have lightning conductor?​

Answer 1

Explanation:

Why it is necessary to have a lightning conductor or rod in all new buildings?

All tall buildings now have lightning conductors. Lightining conductors carry the electrical current away from the building and safely to the ground. If an unprotected building is struck then any moisture within the fabric of the building turns instantly to steam, with dramatic results.

Modern Lightning Rods

You don't see them because they aren't the tall monstrosities that they once were. Most people won't notice or recognize them because they are very inconspicuous.
