A film based adhesive tape will work for a short period of time until the water begins to cause delamination at the edges.  This method will work for short term experiments, but will not hold up under long term exposure.

Does anyone  have any links or references to how far out the "skin effect"  goes vs voltage applied, ie... how thick can the insulator be for a given voltage?

I know I can find dielectric properties of different materials, but how far out the "skin effect" reaches seems somewhat mysterious to me.

Thanks,
Mike

I think the insulator needs to the glued  to the cathode just like JNL.

My test cell is 3/4 in diameter by 3" long, when It was insulated using a finger from a latex glove, outside water, the latex was nice and snug against the tube, but when in water, the latex would get loose and kind of expanded and be almost toucing the outer tube.

ya'll are actin fuckin crazy with the tape and googly-rubber glove talk.
Water tight  the top and bottom of the inner tube and letting nature build its own non-conductive coating over the outside of the tube like it already does.

Or just use plates and insulate the ends.

I have read that 3M makes a tape which can be molded very well and is for high voltages. Called 3M grey rubber self bonding silicone HV tape I believe...

Hi,

I have insulated my tube with heat shrinkable polymer and its strong and 100% waterproof.
Important is to use a NON POLAR  material.

Hi guys, I'm not  real smart about this but have a suggestion.
Sometimes wireing is coated with varnish so how about some marine varnish.
Sounds simple, did someone try.

Hi,

I made an extra topic for my JL replication to keep it all together for myself.
If you want the same, just ask..... 8) or make one your selfs
