anyone have a good source for high voltage wire?

What gauge?, What insulation rating (voltage?), single conductor? Multi-conductor?

Automotive spark plug wire either resistive or solid conductor is available in 25 ft.
rolls. Should be good to 80,000 volts or better. Usually about 14 ga. wire in the solid
conductor type.
You can also find it used for HVAC heating applications.

Details- needs to handle 30k and be shielded.

Another source is the wire used for neon signs. Solid core, high voltage wire is used in HAM radio onboard sailboats to get the signal up to the backstay - and not get a "shocking experience!"Very similar to the autoignition wire.

BTW - you can get GTO-15 through ANCHOR wire - but find an alternative to the boat store prices!

How much do you need? another source is CRT high voltage cable, typical operating voltage on colour crt 30,000v

I need about 25 ft for 2 lasers.

Also mind what connectors you use! Connectors for 30Kv shielded are big and expensive. I can't tell you what connector, I just know it from lower KV ratings. And if it's not DC, that will also affect the rating.

Belden 9867 comes in 25ft & 100ft 30,000v (60,000 breakdown)
belden separate braid for shield 8663.
I have no idea of cost.
