Glossary - Dielectric

Dielectric

Dielectric is the insulation layer between the inner conductor and the shielding. The insulating material between the inner and outer conductor of a coaxial cable is a decisive factor for the characteristic impedance and the attenuation of the cable. Therefore, different materials are used here depending on the intended use of the cable. See table below.

Flexible coaxial cable - single shielded

Single shielded
Structure of a single shielded coaxial cable:
1 = inner conductor (Solid or litz wire (1b))
2 = dielectric medium/ insulation
3 = braided shield / film
4 = outer sheath
