And if you don't believe the 'high-end' part brush up against a
66-block
while your well grounded, you will be singing in the high-end!!!  At
that voltage I think the differential created by the twists would cancel
anything including small animals out along the line.

It's only 130VDC, at moderate (but not high by any means) current.  This is 
26AWG, after all.

(only...  I work in industrial power, in fact there's 575VAC at my desk
where
I'm typing...)  The medium voltage (4160VAC) stuff is out back.  :-)
