If you’re seeking a straightforward answer to the question of whether overhead powerlines or underground power is better, you won’t find it here. Over 93% of Australian households are supplied with overhead service cables, but recent government initiatives have led to a gradual increase in underground electrical systems.

The decision between the two is not a simple one. Let’s delve into both options to understand the reasons behind the choice between overhead powerline service cables and underground electrical systems.

An overhead service cable consists of conductors that facilitate the flow of electricity. Suspended by poles, these cables can carry electrical energy over long distances. You’ve probably seen them in your front yard, running from the street’s network pole to your property or a private power pole.

Similarly, an underground consumer main draws power from the street’s network, but the difference lies in the cables being buried underground and connected to your property’s meter box. In some areas, especially new subdivisions, new suburbs, and parts of Sydney’s CBD, underground electrical systems are mandatory. These systems can provide either single or three-phase power supply.
