coax cable breakdown

Hi, everyone,

Does anyone know where I can find any materials on brakdown voltage of coaxial cable?

Thanks!

They are usually listed in manufacturers' data sheets. Expect values in the kV+ range.

Look at the attached file from Suhner catalog.

In any case consider we are using RG214 at 9 KV ( spark plug cable for special application ) without any problem since 1995.

Thanks a lot!

But why did I fail to find the attachment?

In fact, I find some data in Pozar's Microwave Engineering. However I fail to find what I want.

I get it.

hi .. i used rg58 for 5kV for years ;0)

What application do you use the cable in with such a high voltage?

high power tube power amps for short waves .. abt 5kW power out
