wire sleeve for inductor winding

J

Jamie Morken

Hi,

I am winding some 12gauge equivalent litz wire (660 strands of 38 AWG
wire) onto a plastic inductor bobbin (EE65 ferrite core) and would like
to have 500Volt insulation between the windings. I was thinking a
fiberglass braided sleeve around the wire would work, is this a good
choice or is there a better way to insulate the wire from one turn to
the next? I plan on using 1 or two layers on the inductor, the max
voltage across the inductor is about 500V, so for one layer of 8 turns,
maybe the enamel on the litz wire is sufficient, or is it still good to
use a wire sleeve? The litz wire is "unserved", so it is just the 12
turns per foot, and no "circumferentially" wound string on it which
could help with insulation if it was there.

Here is some fiberglass sleeve I Was looking at:

Any other good solutions?

cheers,

Two layers of masking tape works well enough. Soak in hot wax to fix
things together semipermanently (ok fine, transformer varnish).
