The Benefits of Switching to Underground Electrical Power

Four separate incidents involving contact with overhead power lines resulted in serious injury and tragedy in the first half of 2023. These incidents highlight a concerning trend, but a solution is on the rise.

The underground cable market is projected to grow significantly by 9.4% annually between 2024 and 2031. This shift towards burying power lines below ground represents a move towards a safer, more reliable future for workers and communities alike.

Let’s explore the advantages of underground power lines and why they’re becoming the preferred choice.

What Are Underground Power Lines?

Underground power lines are essential components of modern electrical systems, offering a reliable and safe power supply.

Definition and Components

Underground power lines consist of underground cables and buried power lines that form part of the underground electrical systems. Unlike overhead lines, these lines can be installed beneath your property, reducing the need for power poles.

Underground cables and underground electric infrastructure involve electrical cables and underground utilities that distribute electric power to your home.

Differences from Overhead Lines

Underground power installation is often more expensive than overhead power systems. Yet, the benefits of underground power lines include being less susceptible to severe weather and high winds, which can cause power outages in overhead power lines.

Underground systems are more reliable and have a lower environmental impact. Overhead power poles require regular maintenance and are easily damaged.

Underground lines can also enhance property values and are much more aesthetically pleasing. Western Power and local government initiatives, like the underground power program, aim to replace overhead electrical infrastructure with underground service lines.

Why Consider Burying Your Power Lines?

Burying power lines offers several advantages that improve safety, reliability, and aesthetics.

Enhanced Safety

Installing underground service lines reduces hazards associated with overhead electrical infrastructure. Underground power cables are protected from external factors like falling branches, providing reliable, safe power.
