Overhead versus underground cables – what’s the difference?

Overhead service cables are cables that are suspended by poles and can carry energy over a pretty significant distance. They’re likely what you’ll see over head of suburban homes, from street or private power poles. They’re useful because they can be either single or three-phase depending on the needs of the property. A whopping 93% of Aussie suburbs use overhead rather than underground, generally because they’re cheaper to install and maintain, and it’s easy to identify and fix any issues.

Underground cables carry mains power from the street network to the property’s meter box, and are mandatory for new subdivisions, suburbs, and some CBDs. Undergrounds offer the benefit of being out of site, and being underground, mean that there’s less likely damage during storms or risk to wildlife.
