Absolutely, If you come into contact with them you can be seriously injured or killed. There is an enormous amount of power running through them. There is also the proposed idea that living near them can increase ones risk of cancer due to the strong electromagnetic fields produced by the lines. I would go further and warn that you don't even have to come in contact to be hurt. Very high voltages can arc over some distance, so even getting close can kill. If you encounter a downed line, the current flow through the ground can produce a 'voltage gradient'. This means as you get further away from the line, the voltage present on the ground decreases. If you take a step toward the line, one foot could be standing where the voltage is, say, 500 volts. No problem so far. But as you step, the other foot could land where the voltage is 700 volts. Oops, now you have a voltage from foot to foot of 200 volts! Nasty. Bottom line - stay far away from high voltage lines! If one is down on or near your vehicle, avoid the temptation to jump out and run. Remember the voltage gradient. Wait for rescue workers to de-energize the line.

Why overhead electric cables sag on hot sunny days?
There's little choice. Conductors (not 'cables') sag, because of their weight. However, there's also a practical reason for deliberately allowing conductors to sag; if they were too 'tight', then they would not be able to contract during cold weather without pulling the poles over.
What has the most common element used in wires?
Copper is used in electric wires because it is the best conductor of electricity that is known, apart from silver which is slightly better. For overhead wires a common material to use is aluminum because it is much lighter, although not such a good conductor. Overhead high-voltage wires usually use aluminium stranded wire with one or more steel strands in the centre to give strength.
What two metals are most common in electric wires?
The two most common metals in electric wires are copper and aluminum. Copper is highly conductive and is used in most household wiring, while aluminum is often used for overhead power lines due to its lower cost and lighter weight.
What happened when sparky crossed the wires for his electric blanket and his toaster?
If Sparky crossed the wires of his electric blanket and toaster, there would likely be a short circuit, leading to a potential risk of electric shock, overheating, or even fire. It is extremely dangerous to mix different electrical devices in this way, so it should be avoided at all costs.
Who fixes electric poles and wires?
Electric poles and wires are usually maintained and repaired by electric utility companies, such as power companies or municipal electric departments. These organizations have trained technicians and lineworkers who are responsible for installing, maintaining, and fixing electric poles and wires to ensure a reliable electricity supply.
What normal household objects are 2 2.5 and 3 millimeters in diameter?

Why are wires hung loosely in summer?
beacuse is good
How does electric get to your home from a dam?
Along wires. Copper wires underground or aluminium overhead.
Why are frayed wires dangerous?
Frayed cables/wires can cause fires.
Why not touch overhead cables with branches?
Touching overhead cables with branches can be extremely dangerous because these cables often carry high voltage electricity. If a branch comes into contact with the wires, it can create a path for electrical current to travel, potentially causing electrocution or fires. Additionally, the added weight of branches can cause the cables to sag, increasing the risk of accidents. It's important to maintain a safe distance from overhead power lines to prevent these hazards.
What does a utility pole do?
Usually, supports overhead electric/telephone wires and equipment.
How has copper been used?
Copper has been used lately in wires and cables like coaxial and electric wires.
Why is it dangerous of overheating cables?
overheating cables can cause the insulation and other wires to melt and this removes dangerous fumes. this can also lead to a fire or an explosion.By: Aleeq Salim

Can you play the guitar well without any wires?
The "wires" are called guitar chords or patch cables. And yes you can, if you have a guitar with an acoustic body (not an electric guitar, but acoustic or acoustic electric).
Why are overhead electricity cables never tightly over a pylon?
Overhead electricity cables are not tightly strung over a pylon to account for factors like temperature changes, wind-induced movements, and maintenance needs. Having some slack in the cables helps to reduce stress on the wires and prevent damage or breakage.
