Structure of Coaxial cables

Structure of coaxial cables

Coaxial cables come in different shapes. The big distinction lies in the inner conductor (solid or Leiteitungung - rope of several fine conductors) and the shielding (single or multiple execution). The selection of the correct line always depends on the application and the frequency to be transmitted.

Example: When used outdoors, attention must be paid to a suitable sheath (more here), while for use in continuous motion, a cable with a strand inner conductor and a braided shield should be selected. In the overview below you can compare the different cables and select the appropriate one for your application.

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

Flexible coaxial cable - double shielded

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

Low Loss cable

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

Low Noise cable

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

Semi-Rigid Coaxial

Semi-Rigid – hand formable cable
Structure of a semi-rigid coaxial cable:
1 = inner conductor (Solid or litz wire (1b))
2 = dielectric / insulation
4 = outer sheath

Semi-flexible coaxial cable

Semi-flexible:
Structure of a semi flexible coaxial cable:
1 = Inner conductor - completion as solid wire
2 = Dielectric / Insulation
3 = corrugated tubing
4 = outer sheath
