Maximum voltage in coaxial line
===============================

A coaxial waveguide is an electrical cable consisting of a central conductor and a
shield arranged coaxially and separated by an insulating material or an air gap. It is
used to transmit radio frequency electrical signals. An electrical breakdown is a
phenomenon of a sharp increase in current that occurs when the field intensity is higher
than the critical one — dielectric breakdown intensity.
