Structure of a triaxial cable:
1 = Inner conductor (completion as massive wire or litz wire (1b))
2 = Dielectric medium / Insulation
3 = Shield braiding or foil
4 = Dielectric medium / Insulation
5 = Shield braiding or foil
6 = Outer sheath
Structure triaxial cable
A triaxial cable is a special form of the coaxial cable, that consists of three concentrical conductors. The latter are seperated by a dielectric medium and a shielding. Application fields are video technology and electronical metrology. In electrical metrology femtoampere currents can be measured with a suitable construction using Triaxial cables.
Due to the higher production costs, the triaxial cables are more expensive than coaxial cables.
