Wire for high voltage pulse

R

Ron H

Guest
Can I use some RG-58/9 coax as a conductor for a fencer? The unit pulses
about once per second at about 2500 volts. I need to feed a fence with about
25 feet of conductor underground so I thought maybe using the coax leaving
the shield ungrounded might work. Any thoughts? I figured that if I grounded
the shield, it might act as a choke......

Ron:

There are many types of RG/6 58 or 59. They all have different
dielectrics so the ratings will all be different depending on the type.
However, I do not believe any of them would have a 2500 Volt rating.
Probably more like 300 or 600 volt.

If you are dead set on using coax, don't hook the shield to anything on
either end. And, put it in some PVC conduit when you burry it. This might
work. To do it right I would get some HV wire at your local TV shop. Also,
this would need to be in a PVC pipe of some kind to keep water and critters
away from it.

At this sort of frequency, the shield acts mostly like a bit of
capacitance. And that doesn't vary much whether you ground it or not,
once the cable is buried, since the soil surrounding the cable is also
"grounded". But leaving it floating makes it a shock hazard. I would
ground it. I also suggest that you strip the shield back a couple
inches from the ends of the internal insulation, to keep the center
wire from arching to the shield at the ends.
 
The data sheet that I have indicates that the RG-58/9 center conductor has a
dielectric breakdown voltage between 1900 (58) and 2300 (59) volts. The
outer covering is probably in the 500-600 volts range. Thus I am assuming
that they would hold up for the max 2500 pulse leaving the shield
unconnected.

Do you really think that the PVC pipe is necessary?

That depends on weather you want to dig it up again someday..

I suppose you could find some "Direct Burry" coax, that would last longer.

John:

I see you are up to your usual arrogance.

I apologize, I forgot your opinion is the only one that counts.

Your very special.

You may want to consider removing the word "Professional" from you self
description, Last I heard, "Professionals" don't act like children.

And you will notice this time I am replying to the entire group so
everyone can whiteness your behavior.. (thanks for the heads up)

This fucking moron, Ziegler, obviously has no clue, so I bottom posted
his reply, above, so this exchange would make sense.

If you care to continue, Ziegler, please reply with bottom posts and
run your posts through a spell checker since you can't seem to get it
right natively.

Now, as for the statement that you're replying to the group "this
time", let me then take the little discussion which has led to your
getting your panties in a bunch public as well.


First, I received this Unsolicited Commercial Email (SPAM, asshole)
message from you:


John:
You might want to look at our selection of National Control Timers.
We might have what you need allready put together.


To which I replied:

If you'd have bothered to post to the relevant newsgroup instead of
SPAMming me, your lead might have been useful and appreciated.


To which you replied:

Geeze!

I only replied to your question. I thought you might find the
information useful, as in there may have been something there to help
you out. Why so sensitive?


To which I replied:

---
No, you didn't reply to my question since I never asked one about an
off-delay relay. Matter of fact, If you'd have read the thread you'd
have seen that I sent the OP to Grainger's for exactly what he was
looking for.

I'm sensitive because I don't like SPAM or UCE. You sent me an
Unsolicited Commercial Email message (SPAM) and I don't appreciate
that. If you have comments to make about posts on newsgroups the
proper netiquette is to keep those comments on the newsgroups.

Please don't email me again unless I specifically request "help".

Thank you,


To which you replied:

Wow!

Chill out on the caffine.

No worries, I'll make sure and avoid you.


---
So, since I pegged you for the SPAMshit you are and made that crack
about "Big help" (which I thought was warranted since you're supposed
to be in the electronics biz and should have known where to send him
for this direct "burrial" coax) you're now trying to to defend
yourself with your stupid slurs? Keep it up, dumbass, I _love_ to
pin back the ears of stupid shits like you in public.

GTO-15 is another good choice. Check your local neon sign shop(s).

Are you stuck with a bunch of coax cable or something? It's a terrible
choice for this job. Go get a 100' spool of high-voltage wire at the
TV repair shop - the kind they use for the anode lead. And put it
in PVC pipe.

Good Luck!
