Letter 30024
Non-conductive metal for lightning rod
[California]
|
++++
I'm asked to bid a 130' tall pole with a 2'6" base and
ground mounted in Las Vegas Nevada is there any non
conductive metals I could use.
Thanks,

First of two simultaneous responses ++++
NO. By definition, metals are conductive. Maybe
fiberglass? In any case, for something that tall you need a
structural engineer.

Second of two simultaneous responses ++++
Metals, by definition, as electrically conducting. The
only way to make them "non conducting" is to put an
insulator, such as a piece of plastic, in series between two
rods.

Yes you can use a Aluminium with Zinc plating bar which
is fully non-conductive. It is used for engine testing on
turbofan systems. Its an expensive but safe option.

Huh?
We appreciate the response, Jhon, but I think you've certainly
misunderstood something.

Where can I get some of that Aluminium with Zinc plating from? I
have really bright bulbs for my car, and it is melting away the
plastic plug. I want to make something that will stand the heat -
this Aluminium with Zinc plating sounds like a good idea if it isn't
conductive.

Teflon coating is a material which is zero conductivity and its
melting temperature is 327 degrees celcius. Hope it helps
