Line clearance question.

[jefflovstrom]

I got in my lineman books It take 1 tenth of 1 volt for 1 sec in any voltage to kill. The 1 second part is because that is how long it takes for musle contraction. Ohms is resistance and your bodys is about the same as water. I cant posibly rember all of it to many books to many years. Rope thanks for posting that u got me off my but and into the books. James

That's why we call him 'Rope'!

We still glove 4kv of pole under my contract, but do so as little as poss. It was good talking with you.

It was good talking with you as well, I bet you test them gloves regular if gloving off the pole, anyway stay safe friend. I know a little of the lines man side, very little and a lot on the line clearance side

Ok guys I am getting some flak about my ohms being the killer deal. I will try to explain my meaning and please understand I am simplistic. Since this subject is line clearance and the known voltage and amperage is well above the 1/10 of one amp in 12vdc known to kill a human.

I will explain by example what I am meaning as ohms is killer! Example one we have a climber with high tie in, he is standing on a limb above a burning "close in line clearance terminology" limb. He is using a kiln dried, dry ash pole pruner tested to infinite ohms, as most safety gear is for power line work. He is clearing the close twigs to obtain enough clearance to rope the limb clear. He clips one twig that makes contact with primary but feels nothing.
Next example he is in same situation but is using a aluminum silky pole saw what, besides stupidity, just made the difference and killed this climber?

With distribution lines the example is consistent with my point but as voltage and amperage increases like on 500kv lines humid air etc can reduce resistance, so all factors come into play it is just resistance to me is the buffering factor.

Enough talk about powerlines whats wrong with that 200t.

Hey .. think Rope threw his 200T in pile behind garage :thinking:

But .. enough talk about powerlines.. for that matter lets get this snow melted and get some tree work done.

It is a manufacturing dilemma and engineering mishap

Can we quote you on that !

Hey .. think Rope threw his 200T in garbage pile :thinking:

But .. enough talk about powerlines.. for that matter lets get this snow melted and get some tree work to do.

Fixed it fer ya:angel:

Sure and add overpriced and hyped rubix cube that's well marketed

Rope do u not like the 200t. That supprizes me. How much for it I need anouther.

Lol I will have to repair it before selling it. I liked it when it ran right but that was short lived. Its in a gazillion pieces right now and if I make a little extra dollars will probably get it going again. I wish they were priced right 600 for a 8 month saw is too high. I also wish flippy's were optional

What kind of parts you looking for. I run 3 of them so none of them get a whole lot of time but 8months sounds pretty short. But then again I have a 08 395 that only made it 2 weeks, they dont last long if u dont move them out of the trucks way. Let ur brandnew 395 get ran over. I almost teared up.

To hell with that..... I have a (new to me) sled and want to use it. Besides, I need a couple of months for the body to recoup before climbing again.



As to the power question, you're all wrong...... its being grounded that kills you.:hmm3grin2orange:

Ok.. how is a couple more weeks Beginning of Feb .. is that compromise enough.

...... its being grounded that kills you.:

Well one way to look at it.. mind you I can take you to a transformer station (actually any of them).. and get you pretty warm even if you are not touching ground.

See in a round about way thats ohmsoke:

Lol started work each mourning at the sub station

It is in my safety materials 1/10 in 12vdc not saying yours is not right too but I tested on this rule. No matter it is very little voltage ohms is what kills you imho.

Amps do the killing.
Volts are what pushes the amps through your bod.
Ohms is what protects you from the volts & amps.

Sooo...I gotta disagree rope. Ohms is NOT what kills, it's not having enough of them that will kill you, given some exposure to the volts and the amps.

A little high school physics: V=IR
where V is volts, I is the amperage, and R is ohms resistance. When Voltage is very high, in order to keep the electrocuting current very low, you need almost infinite resistance.
