This looks to be very much cheaper than the Dupla cables I've seen.
I would very much be interested in learning more about this wire. My
criteria would be:
* Per-unit resistance such that 15-25 feet would provide 30-80
watts or so at low voltage levels (9-24VDC).
* Insulation thick enough to provide more protection than Radio
Shack wire-wrapping wire.
* Insulation thin enough to be flexible and give good heat
transfer.
* Stranded might be a plus -- to resist breakage.
Please post any details you can find. Thanks. BTW, does anyone have
a Dupla cable that they've not yet installed? Perhaps they could take
it to a local electrical supply house and ask about matching up some
bulk wire.
