Re: [TCML] Wire recommendation for new secondary

[mddeming@xxxxxxx]

Hi Craig,

There is no "ideal" size. A majority of coilers find a "good, workable" compromise is 1200 to 1800 turns on a secondary.
You don't say if 30" is the desired length of the winding or the over-all length of the tube. Assuming you want a 30" winding, and 1200 to 1800 turns, then the wire thickness, including insulation, for a close-wound coil would be 30/1800 to 30/1200 or 0.0167" to 0.025". For example, a heavy-build Essex magnet wire, this would be from 23 to 27 AWG. Some successful coils have been reported with as little as 700 turns or as many as 2200 turns and some people leave extra space between windings (space-wound), but these are exceptions.
A nominal 6" coil will require 38"-40" per turn so your looking at 4000'-6000' of wire. A rough rule of thumb is a 6" coils needs at least a mile of wire.

Hope this helps,

Matt D.

Hi all, 
 
I am winding a new 6" x 30" secondary coil. What awg wire size would be
referred for this size coil? I have a 16K/65ma transformer which can handle
ore than its rated load for short periods.
 
Thanks,
 
Craig
