Abstract
A coaxial cable (10) includes an outer barrier (12, 14, 16) that seals the coaxial cable from air and protects the cable's conductors (18, 20) form oxidation in a fire. Such an outer protective barrier may include a fire retardant tape. A dielectric (22) separates the conductors and may comprise a ceramic (23) embedded in a dielectric material (25), or ceramic beads in a braided ceramic mesh.
