If you plan to set up a new industrial plant, the electrical power supply you use is quite possibly among your main priorities. As such, you might have a hard time choosing between overhead and underground power transmission lines.
However, underground power lines have several advantages that might interest you. Take a look at a few main reasons why these lines are a good option for your industrial plant.
They Are Less Likely to Suffer Damage in a Storm
When a storm hits your area, underground power lines are less likely to get damaged than overground power lines. That's because underground power lines are buried deep in the ground, unlike overhead lines that remain suspended above the ground.
Overhead lines are exposed to all kinds of precipitation, be it rain, sleet, snow or hail. That's why they're more likely to get damaged when a storm hits your area. Underground lines, on the other hand, lie deep in the ground where they are less exposed to these elements.
Underground power lines may still be damaged by water, though. So if a storm is accompanied by extremely heavy rain that causes flooding right above the underground lines, there's still a risk of damage.
But a good power line installation expert will ensure that the exposed cable terminations aren't too close to potential flood areas. In addition, they will use special power cables that can resist any water that finds its way down to the underground cables.
They Limit Electromagnetic Interference
If your plant uses sensitive equipment, underground power lines are typically a better option than overhead lines. That's because underground power lines have less electromagnetic interference (EMI), which is the energy radiated by electrical and electronic equipment toward other devices.
EMI can interfere with sensitive equipment or telephone lines and affect their performance. This interference might create problems for employees, particularly those who handle the sensitive equipment or perform other electrical work.
Thankfully, most underground power lines have a protective sheath that prevents any interference between the underground power cables and other electrical equipment. Plus, the earth above it will add another layer of protection against EMI. So, if you use underground power lines at your industrial plant, you can be sure that electrical power won't affect the operation of your sensitive equipment or communication channels.
If you use underground power lines for your industrial plant, you'll benefit from these lines' resistance to damage by wind and storms, their ability to limit EMI, and the ease of installation. Reach out to power line installation professionals to learn more.
