Non-conductive metal for lightning rod

Non-conductive metal for lightning rod

Letter 30024

++++

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,

NO. By definition, metals are conductive. Maybe fiberglass? In any case, for something that tall you need a structural engineer.

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 Celsius. Hope it helps
