Triaxial cables, a special variant of coaxial cable, consist of three concentric conductors separated by a dielectric and a shield. This structure gives them improved performance and makes them an important tool in video technology and electrical measurement.
Triaxial cables are used in electrical measurement technology in particular, as they enable extremely precise measurements. The second outer conductor creates a small protective atmosphere so that even very low currents and signals can be measured without external electrical influences. Even currents in the femtoampere range can be measured, which is of crucial importance in many applications.
However, it is important to note that the processing of triaxial cables is generally more complex than conventional coaxial cables due to their more complex structure. This higher manufacturing effort is reflected in their technical performance and precision, making them a worthwhile investment for applications requiring the highest accuracy.
Triaxial cables are available in our online shop and also pre-assembled upon request. It is important that you tell us the exact signal distribution when you make your enquiry.

Due to the structure of the triaxial cable, it is easy to see that the connectors differ from those of the standard coaxial cable. For further information, please do not hesitate to contact us.

Here you can see the properties of the individual coaxial cables from different manufacturers at a glance.
The cable sheath is the outermost protective layer of the coaxial cable and is usually made of one of many plastics. In the following overview you can find out more about the different sheath materials in our range.
Consistent performance and quality are very special concerns for us. To ensure that this remains the case in the course of your application, we have now added Telegärtnercover caps to our range. These protect your connectors from external influences such as dust as long as they are not connected to your application. For convenient handling, our cover caps are also optionally available with chains so that they do not get lost when not in use. Every cover cap in our range is waterproof to IP67 or IP54.
Protect your cable assemblies now with our new cover caps!
Did you already know? We can assemble your cables with matching connectors as required. Simply use our cable configurator and your desired cable could be with you in no time!
Our new Timag 100 tester quickly and easily tests a coaxial cable for transmission quality or attenuation at specified frequencies using a reference cable.
One or more frequency ranges are tested by means of signal transmitters up to 3.8GHz. No programming knowledge is required to teach the test – one or more reference cables are sufficient.
The “Timag 100” was developed for service and quality assurance, cable testing and cable diagnosis of coaxial cables.

Perfect for:
Regular inspection of coaxial cables
Service and quality assurance
Cable testing and cable diagnosis of coaxial cables
Many coaxial cables are designed to withstand high temperatures of up to 200°C without damage. These usually have a dielectric made of PTFE and an outer sheath made of FEB, PFA or PTFE. Cables with a dielectric and sheath made of Kapton are even temperature-resistant up to 250°C.
Please note: If temperature-resistant cables are assembled with the matching connectors and bend protectors, the maximum temperature is always that of the component with the lowest temperature resistance. If the coaxial cable is suitable for temperatures up to 200°C, but the connectors are only suitable for temperatures up to 100°C, the maximum temperature for the entire assembly is 100°C. If the maximum temperature is exceeded, the cable must be assembled properly. If this is exceeded, proper functioning is no longer guaranteed.
Many of our cables have standardised fire properties according to IEC60332-3 or DIN VDE 0472-804. As a rule, the basic requirement for this is that the cables do not contain halogens, whose fire properties would be very unfavourable. When substances such as chlorine or bromine burn, toxic substances are produced and a lot of smoke is emitted, which is why they are banned in many areas of application. Cable sheaths made of PVC contain halogens and are therefore not suitable for these areas. Their advantage, on the other hand, is the cheaper price compared to other materials.
In our range, many halogen-free cables are provided with a manufacturer-specific additive. Examples are LSNH (Low Smoke No Halogen), LSZH (Low Smoke Zero Halogen) or FRNC.
