[Lowfer] Al Loop Conductor?

[Scott Tilley]

Hi Warren

My 100m perimeter LF loop is constructed of similar AL wire.  You'll 
find it the PERFECT loop conductor as it's much lighter and cheaper than 
copper.  The conductivity issue is not that big of a deal as my 
conductor had much better conductivity than calculated.  I figure this 
is due to the increased surface area based on the stranded nature of its 
construction.

Another nice feature of neutral supported cable type conductor is the 
insulation is tough and will have been tested by UL/CSA or similar to 
have a dielectric withstand in excess of 3KV.  No arcing here ever.

Just ensure you use a suitable compound on any joints to mitigate oxidation.
