Overhead Lines vs Overhead Cables: Which Option Is Right for Your Subdivision?

Electricity distribution network service providers are the companies that you need to turn to when you want to connect your residential or commercial subdivision with electricity. These companies control the whole process of bringing the electrical service all the way from the distribution grid's substations to your private property.

Electricity is delivered to homes and businesses across Australia in two main ways: by using overhead lines or underground cables. Each option has specific pros and cons that must be weighed up to determine the right method of power distribution to new subdivisions. Continue reading to learn more about overhead and underground electricity distribution systems.

1. Overhead lines

This system of electrical distribution requires using utility poles to deliver electricity to consumers. It is by far cheaper than undergrounding because it simply requires the installation of wires on poles. It also minimises disruption to land since no deep excavations are required to install the electricity supply infrastructure. 

Overhead lines can carry higher voltages than underground cables because they have no insulation that may inhibit heat dissipation. They're the ideal choice for property owners that want the maximum possible voltage supplied to their properties. They're also easier to access for maintenance and repair purposes.

On the downside, overhead power lines can be a public safety concern because they're installed in the open. Plus, they may not augur well for property owners that prefer to keep their utility services out of sight.

2. Underground cables

As the name suggests, this electrical distribution system requires using buried wires to power up a property. It costs more upfront because it requires digging trenches, cables, conduits, manholes, and many more. However, it is the safest method of power delivery to homes and businesses across the country. Plus, it is great for aesthetics because no visible signs of the electrical service can be seen above ground.

Just like overhead lines, there are disadvantages to keeping your power supply cables buried outside. Limited heat dissipation in underground cables can reduce the maximum voltages that can be carried by the cables. Plus, underground systems are more difficult and expensive to access when it's time to undertake maintenance and repair on them.

When it comes to connecting new subdivisions with electricity, no system is regarded as the best one for all situations. The right electricity distribution method will depend on your specific needs, as well as the specific type of power distribution network that exists in your area.
