The problem is not Temperature.

your wire insulator for any Bifilar that will oeperate at HV, will have to handle the max voltage. so Stan talked about 20KV, each wire insulation will have to handle at least 12KV.

I got a quote for the perfect wire for this but a little to much for my wallet;

Subject : RE: Need price on some wire for R&D

Hi,

I'm doing some R&D and need some magnet wire to make
an high voltage transformer 20KV. the HV winding is
to be bifilar wound so the wire would need to resists
the HV field that will build between the 2 windings.

I was looking at your website and it looks like your
24-27B51S migh be the right product for this
transformer.

let me know your opinion, a price list and where can
I get the wire.

Thank You

Here is the responce:


I think the part number you referenced would work. PN
24-38B44S has an even higher voltage withstand due to
additional insulation thickness.

PN 24-27B51S (~686 ft/lb) $29.26 /lb. 20 lb. min.
PN 24-38B44S (~670 ft/lb) $42.96 /lb. 20 lb. min.

This wire is sold directly from the factory. How much
wire are you looking for?

I wrote back asking if they would cell only 4 lb, and they never responded.

Lol i knowm somebody who told me the same ...

Thats why i'm not getting bifilar , you need to have them seperated by the bobbin material.

jolt,

I don't think Stan used such exotic insulations.  I have discharged HHO from water with very small insulated wires and the water released the gasses before the insulation broke down.  I may be all wrong but remember we are looking at a .0625 gap in the cell.  I believe that even double insulated core wire will send voltage across that gap before going to ground through the insulation.

Very exotic... Pyre-Ml is the highest temp rating

240 degrees

But true it wasnt as thick as that lol

This is the wire I plan on using
Secondary 36 AWG
Primary 30 AWG
Chocks 41 AWG or 430FR 36

ENGINEERING HIGHLIGHTS
1. THERMAL CLASSIFICATION
THERMALEX 200® is class 200 when measured
in accordance with the ASTM D 2307 test
method. Heat shock resistance exceeds 220°C.
2. THERMOPLASTIC FLOW
Thermoplastic flow or cut-through temperature
of THERMALEX 200® is in the 365°C plus range;
well above maximum process conditions found
in molded coil work, trickle impregnation
processes and standard pre-heat varnish cycles
specified for normal Class 130, 155, 180 and
200 systems.

jolt,

You may be right I may need this higher class insulation.  I remember a long time ago trying to shoot a blasting cap with a taser gun and couldn't get it to fire because of shorting out in the wires by the gun.  But this vic voltage is going to be built through the pulsing electro action of the circuit and not loaded into the secondary and chocks all at once so i suspect that the .0625 gap will get to disscharge all of it.

Bro you got amazing quality would love to have that 41 awg and 28  ...

The polynylon is very common , you have more than needed its better..

dankie,

I've got to try both of them before I can give them up.  But I have more than I need and couuld cut some of it out for you.  If it works I'll have to have more anyway.
