What Are the Advantages of Running Mains Power Underground?

Underground power installation work offers several benefits that you don't always see from overground connections. Of course, there is nothing wrong with a new mains connection that is conveyed over poles or pylons — this happens in nearly every part of the world. That said if you are thinking of connecting a building to the grid in Australia, especially a remote one that is nowhere near other structure, you may want to consider the merits of underground power installation. Why?

Less Visual Clutter

Although digging a trench is something that often creates some mess while it is being carried out, once a power cable is connected and the trench is filled in once more, there is nothing to see. In places where there is a beautiful natural environment to consider, the case for a subterranean power installation virtually makes itself. So long as tree roots can be avoided when the trench is dug, the impact on the natural world should be very minimal.

Narrow Strips of Land

When you install overhead cables on posts or pylons, you need clearance either side of them. In places where there is plenty of local bush growth, this means that a pathway will need to be cleared for the cables to run through. Importantly, it will also mean needing to maintain that corridor in the undergrowth for years to come so that overhanging branches, for example, do not fall onto the cables. With an underground power installation connection, none of this is an issue so you need a much narrower pathway from the grid to the property being electrified.

Electrical Losses

Something that many consumers do not realise is that there are fewer transmission losses with subterranean mains cable connections than there are with overhead ones. Depending on where your meter is installed, connecting a new power installation via a buried cable could save you a great deal of money. Even if the supply is metered locally, the losses you would otherwise see will reflect in your overall carbon footprint. Either way, underground installations tend to be best.


Finally, extreme weather conditions will often impact negatively on an overground power installation simply because the infrastructure that supports it is out in the open. So long as buried cables are placed in culverts with adequate drainage, the local weather conditions should not be an issue, thereby leading to fewer power outages in the long-term.
