The debate about overhead and underground wire cable system has caused strife between the residents of Australia. Although overhead wires can deface the facade of a building, and is more prone to environmental factors and may even be a risk for danger and other electrical accidents, most people opt for overhead cable wires because it is cost effective and accessible for electric repair. Most states already have an underground cable system since it is made compulsory by the government. B but in some cases, especially in old neighbourhoods and streets, overhead cable wires are used.

How do we decide about choosing between overhead and underground power cable system? Here are facts about the cable system that may help you decide which one to choose.

Let’s start with the advantages of an overhead cable system:

- Due to its visibility, we can easily detect if power lines are damaged.

- It is easy to install or replace damaged wires.

- It is safe from flood and flood-related electrical accidents.

- It is cost-effective--it’s less expensive to repair and upgrade.

- It has longer power line lifespan

- Installation of power lines is quick and easy. Electrical posts can be placed on any part of your building area, as long as its location is strategically safe.

The disadvantages of an overhead cable system:

- Unattractiveness. It could lessen the beauty of a house.

- Prone to environmental factors such as bad weather, extreme heat, moisture, harsh winds, dust, and animal disruptions.

- Susceptible to damages caused by nearby vegetation and branches of trees and possible vehicle collisions.

- Vulnerable to lightning damages.

Here are the advantages of an underground cable system:

- No right of way trimming required

- Secured wirings, power lines are intact and safe inside electrical piping conduits.

- Less susceptible to environmental elements.

- Low maintenance

- Suitable for densely populated areas.

- Avoids illegal connections.

- Power lines pose no threat to wildlife, trucks and other possible contact accidents.

While here are the disadvantages for underground cable system:

- Costly--the installation is expensive, electrical conduits cost more especially if it is durable, whereas, in overhead, the cables don’t need conduits.

- Impossible to detect wiring damages.

- Metal corrosion on electrical pipes, and it can be a factor that leads to power line disruptions.

- It may be low maintenance, but once damages are noticeable, the repair cost is high.

Choosing between overhead and underground power lines should be determined by the following criteria:

- The situation of area (location).

- The budget of clients.

- Electrical and building laws of a specific state.

- Which method is more beneficial?
