Sagging Power Lines; Where Does The Responsibility Lie?
Electricity is one of the great inventions to be discovered. It brings life to almost any machine and place. In this century, nearly all inventions created and those yet to come will run on some form of electricity. Today we get to use cars and other machines that run solely on electricity. This form of power has been proven cost-effective. We are discovering more ways of generating electricity with each passing day. When we get home from work, the first thing we do is switch on the electrical outlets in our homes to use our much-needed electrical appliances.
How does this electricity get into our homes and commercial facilities?
Electricity for decades has used one popular of getting to their destination, and this is through power lines. These power lines have been designed for this purpose. Power cables are usually made with copper or aluminum. These materials are used because they are great conductors of electricity. The diameter and length of wires will depend on their function. Power cables for electrical installation for domestic households and smaller commercial facilities are smaller in diameter and shorter in length than power cables that carry power to towns and cities.
So before we understand why sagging power lines occur and who is responsible for them, we need to explain what it is?
Sagging power lines usually happen when power lines or cables made of copper or aluminum expand and contract. Or, when there is an increase in temperature, the wires then increase in length. When temperatures decrease, the copper or aluminum in the wires starts to contract, reducing the size of these power lines. Another thing that causes power line sagging is when there is high consumption through that particular power line. In areas with a very high population, these power lines tend to be seen as sagging than sites with a lower population, signifying a low consumption rate.
What is the measure for whether a power line is sagging?
National Electricity Safety Codes have guidelines to determine whether a power line is hanging too low. We measure it by the distance between the ground and the lowest point in the curve of the power line.
Now to our main topic, the people responsible for sagging power lines are the electrical utility company in that particular area. These utility companies are responsible for this electrical installation and at the same time are in charge of maintaining them. Based on the National Electrical Safety Code, these electrical utility companies must determine which power lines are sagging too low and which ones they need to readjust. Sagging power lines pose a lot of dangers to people and property located around them. In addition, these low-hanging power lines are more dangerous in the rainy seasons because they carry high volts of electricity flow through them. Therefore they must be addressed as soon as possible.
What are the electrical safety codes concerning sagging power lines?
According to the National Electrical Safety Code, there are laid down rules and responsibilities for electrical utility companies in charge of power lines that are sagging. However, these codes differ from country to country, so you might want to check your country’s electrical safety codes before taking any action. Although these companies regularly inspect and repair these power lines, they must replace sagging power lines beyond repair. In addition, safety codes demand that electric utility companies have the trained electricians. The latter can attend to issues of sagging power lines.
When you come across a down power line that is too low and looks like a hazard, the best people to get in contact with is your local electrical utility company.
