Re: Worker Gets Fried when Scaffold Hit Powerlines
Death can sometimes be as quick as a blink of an eye, like the wtc jumpers - that's instantaneous. I think it's more likely this poor guy's leg was moving from muscle contractions caused by the electricity. Dude got completely FRIED...no way he made it through THAT

Re: Worker Gets Fried when Scaffold Hit Powerlines
\\\ wrong, anything in the overhead world has at most 600v insulation for low voltage lines 120/240/480 going to your house called triplex or open wire depending on age of home or upgrading of service. overhead (OH) transmission and distribution lines are not insulated, unless there underground (UG). OH conductors might have insulation but only rated 600v. 4kv jumpers are insulated because of prox. to lineman workings and climbing space. the OH conductor can carry any voltage from 120/240/480 to sky's the limit. the man became a source to ground, period. we use hot sticks made of fiberglass or wood. i have rubbered gloves 12kv from a pole. look up and live might have helped him. the guy who used the stick knew what he was doing. i used a hammer once to knock a guy's hand free, wooden handle :) he lived and his hand healed |

Re: Worker Gets Fried when Scaffold Hit Powerlines
What your talking about is American I assume, and I'd venture to say that in most asian countries it's a completely different standard yet again. Typically where I live transmission are 4160v in residential areas, not 120/240/480, and you're not going to get those until you get to a transformer. 12kv is a measure of amperage not voltage. The minimum working distances from high voltage conductors is rated by the voltage, not KVA or amperage. If you grab a high voltage conductor with an insulating material that is not rated sufficiently, you will get lifted, I don't give a fuck if your hot stick is fibreglass, wood, or whatever...... If it's not rated you will get fucked up. |
