There are several advantages that are associated with the laying electric cables under the ground for transmitting electricity.
The following is a brief outline of these advantages.
Compared to overhead cables, underground cables are much safer. This is because underground electric cables are not exposed to the many dangers that ead power cables are exposed to.
It is cheaper to maintain underground cables over the course of time as compared to overhead ones. In practice, the cost of installing underground cables far exceeds what is associated with the installation of overhead ones. But once the underground cables have been installed, it is highly unlikely that will have to be repaired every now and then as it is the case with overhead electrical cable types.
Underground transmission of electricity is associated with reliability. This is because instances of constant disruption in the supply of power as a result of storms or faults that are associated with overhead transmission lines are not common when power transmission lines are laid underground.
