Commencing Ruggedization

The ruggedized tungsten rods are in from the manufacturer. What a difference!

Per Derek:

I’ve been worried our ruggedization wouldn’t be rugged enough, but then I unpackaged the new tungsten rod we received today. I could do bicep curls with it! I had to take some pix before dropping it at Wolfgang’s—No more messing around, onward to 45kV!

Rods - before and after

Why “ruggedization”? To end mechanical and electrical breakdown of the insulators.

Here’s a look at where the tungsten rods go. Note that the thicker rod will now require a much bigger spark plug and the widening of the hole in the electrode plates. Animation pending!

Good luck!

Now THAT should deliver the goods!

To ruggedize the trigger electrodes
Use silver infiltrated tungsten instead of solid tungsten
Much better conductivity and toughness
These are used in large circuit breakers
242 kv at 2000 amps for 300 ms
tips of infiltrated tungsten are brazed to solid copper
