The insulator within a cable ensures the efficient and safe transmission of signals as well as of current and voltage. Without adequate insulation, the conductors of the cable would be exposed to all kinds of external influences, which could lead to interference and, consequently, signal loss.

ustomarily, solid insulators, i.e. core insulation made of solid material, have been used. Then again, foamed insulations have a number of future-oriented advantages that are becoming increasingly relevant, especially in higher frequency ranges as:

• they allow a wider bandwidth for signal transmission
• they have a greater range due to lower attenuation values
• due to their smaller dimensions and lower weight they are far more mobile and flexible.

Skin/Foam/Skin technology:

A foamed insulator consists of an inner skin that is sprayed on the stranded wire and acts as a so-called bonding agent so that the surrounding foam has a better grip. Finally, a firm, hard outer skin provides stability and protection for the structure.

The following Cordial data cables are equipped with a foamed insulator:

• CCAT 5e PUR LONGRUN
• CCAT 6A PUR LONGRUN
• CCAT 6A PUR QUAD
• CCAT 5e PUR LONGRUN
• CCAT 6A PUR LONGRUN
• CCAT 7A PUR
• CCAT 7A PUR LONGRUN
• CDP1-25

The following Cordial data cables feature a solid insulator:

• CCAT 5e PUR
• CCAT 6A PUR
• CCAT 6A INST-FRNC

Please note: selecting the correct cable for an application requires the careful assessment of a variety of factors including AWG ratings, shielding, insulation, cable length, data class and respective application. It is crucial to take into account all factors relevant to the specific application to ensure signal integrity and the optimum system performance.
