Dear All,
I am working on a project, I looks for coaxial high current copper tubes assembly
Basically first tube surface should be coated hermetically by a ceramic layer as insulator a second tube having larger diameter will cover the first one coaxially and again coated with a ceramic insulator.
Does some has an idea ? about this kind of assembly and where can i find
Thanks
Copper tube transmission line is quite commonly used in the broadcast industry (TV and FM stations).
Check with Andrew Corporation, they may something you are looking for:
What Frequency? What levels of current? Why hermetically sealed? Coating Copper with ceramic? Not good, will flake off.
Need more specifications or what your application is to determine next step.
Hello Aflky, Frequency between 3 to 10 khz Application is induction melting under vacuum that is why hermeticity Coated with ceramic as insulator, alumina seems work good. Voltage is variying 100 to 400 volts and power is max. 50 kwh.
I don't know exactly the reason of why they require coaxial solution absolutely. Seems much more easy to use 2 separated conductor flexible tube Thanks Pierre

Check the Induction Heating MFGRs. They are probably using coax to keep the radiated emmissions down, or to go through a glass seal.
