Hi Gary,
Unfortunately, we do not have a spec sheet. While our wire is rated for direct burial, the intended use is for in-ground pet fences. In-ground pet fence transmit a radio signal rather than any kind of electric current which it sounds like you need for your application. While our wire could be used for these applications, we did not have a spec sheet prepared because we did not anticipate the wire to be used in any application other than in-ground dog fencing.
