Have you ever looked at a telephone pole and noticed those glass or porcelain pieces on top? They might look like just decorations, but they actually have an important job in communication. These helpful items are called insulators, and they help keep our electrical wires safe and our phone calls clear.
Safeguarding the Flow of Electricity
Insulators have a key job: they stop electrical wires from touching the pole or the ground. Imagine trying to make a long-distance call, and your voice suddenly cuts out after a little while. That wouldn’t be fun, right? Insulators make sure all the electricity stays in the wires so our important phone calls can keep going without any problems.
The Variety of Insulators
These simple objects come in many different styles and colors. While a lot of the older insulators were made from glass or porcelain, some were made from wood and glass, and even animal parts! You’d be surprised at some of the unusual materials used. The size of the insulator is important too. Smaller ones are used for telephone and telegraph wires, while larger ones are made for high-voltage electrical wires. It’s like having a special section for insulators based on how much voltage they can handle!
Keeping Voltage in Check
When it comes to power lines, the voltage affects how big the insulator needs to be. Electricity can be a bit tricky and might try to jump across a distance. That’s where the design of insulators helps out. Insulators with wide “umbrella” shapes and large lower parts act like careful bouncers at a nightclub, keeping the wires away from the pole and stopping any accidents from happening.
A Surprising Hobby
Believe it or not, collecting insulators is a popular hobby! This started becoming popular in the 1960s when utility companies began burying their wires, leaving a lot of old insulators behind. As the saying goes, one person’s trash is another person’s treasure. People who collect insulators come from all different backgrounds. Some like these glass pieces for how they look and use them to decorate windowsills and gardens, adding a bit of shine to their space. Others look for specific types of insulators. Prices can vary a lot; you might find one for less than a dollar or even get one for free at flea markets!
A Historical Touch
Most insulators that collectors have are between 70 and 145 years old, and some types haven’t been made since the early 1900s. Anything that’s old and no longer being produced often becomes collectible, and insulators are no different. They hold a piece of history and connect us to a time when communication was just starting to grow.
Appreciating the Role of Insulators
The next time you see one of those interesting glass or porcelain insulators on a telephone pole, take a moment to appreciate how important they’ve been in the history of communication. They might seem like old items, but they’ve made a lasting impact on how we connect with each other, whether through a phone call or a quick text message. Who knows? You might even feel inspired to start your own collection and join the many people who find beauty and history in these simple artifacts!
Firefighters warn public on the hazards of leaving water bottles in vehicles
The hot weather and high temperatures can have a range of effects on people’s everyday life. It is widely known that prolonged exposure to heat can lead to heatstroke, which is why it is recommended to avoid being under direct sunlight for longer periods of time. At the same time, it is essential to stay hydrated and limit strenuous activities during the hottest parts of the day.
This weather can also significantly increase the risk of fires.
Dry heat, strong winds, and low humidity represent ideal conditions for a fire to start. One way of accidentally starting a fire is by leaving water bottles inside a vehicle during high heat. The reason why is that the bottles, especially if they are translucent, can act as magnifying lenses if exposed to high temperatures, focusing sunlight and creating concentrated beams of light.
When light enters a clear or translucent bottle, it can be focused and intensified into a concentrated heat spot. This concentrated heat can build up on nearby flammable materials, like paper or fabric, and potentially ignite them, leading to a fire withing minutes.
This is why firefighters urge people not to leave water bottles inside their vehicle.
In July 2017, Dioni Amuchastegui, a battery technician with Idaho Power, noticed smoke emerging from beneath the center console of his truck during his lunch break.
“At first I thought it was dust, but the window was rolled up so there was no wind,” he shared with Today. “Then I noticed that light was being refracted through a water bottle and it was actually smoke.”
Amuchastegui was quick to get rid of the bottle and prevent fire from starting.
He told his story to his colleagues at Idaho Power and they came up with the idea of filming a video and warning people of the potential dangers of a simple act of leaving a water bottle inside the car when the temperatures are high.
