Read the student note for temprature and what the levels of voltage in the over head cables do to a human body
http://www.educationconnections.co.uk/images/P00203pylonsafety.pdfThe blood curdling sounds good
The pylon voltages are higher than the over head but they have been known to jump several meters so 3ft is a little jump
And answer me a question if the voltage is high enough to jump 3ft what use is 2" of rubber on the bottom of you feet gonna do (path of least resistance is around
)
I have worked with 230/240 volt all my life and been electicuted about a dozen times (smarts a bit but gets the heart running fast
) I sometimes work with 3 phase (415 volts across all phases and have a healthy respect for it (if I got pluged into it I would'nt be here now)
I knew someone who got it wrong with 3 phase (knew being the word) and have heard of a couple of people surviving but when you start talking about 20,000 volts you are in a different league I saw the results at the training course and I wouldn't want to see it for real
Rubber boots of mats will save you from low voltage/high ampage but high voltage is a different beast and can track round the outside
And most people that work on the rail wear rubber shoes or wellys and the result is that they melt when you plug the owner in
Only way to survive is to wear a faraday cage basicly a metal suit that covers all of you this diverts the current around you so you don't die and I wouldn't fancy trying it sounds Bl**dy dangerous to me
The bird on the lines die of old age or being shot they arn't tall enough to electicute themseves as you need to cotact both the line and ground (you can hang from a high voltage cable fairly safely if you are far enough away from any form of grounding but getting down would be hard
)
And the best way to remove someone from a live wire is to push them off with a non conductive pole (dry wooden broom) but if your in a rush and don't have a pole you can barge them off but you have to be moving fast and be either brave or stupid take you pick
And you might want to edit the last bit DK "Thunder" is the sound that Lightning makes as it travels through the air so it travels at the speed of sound whereas lightning travels a tad faster about 186000 miles per sec I think
