If you deal with the subject of cables, sooner or later you will come across the terms wire and stranded wire. But what exactly is the difference and what are the advantages and disadvantages? This article takes a closer look at the main features of wires and strands and highlights the different areas of application and their advantages.
What it’s all about: Wire and strand usually describe the inner conductor of a cable through which electrical signals are transmitted. In order to protect the signal transmission and minimise loss over distances, this inner conductor is protected with a sheath and other components. Further information on the structure of a cable, e.g. a coaxial cable, can be found at koax24.de | Structure.

A single inner conductor wire:
A wire consists of just a single conductor, often made of copper or steel. For very thin cables, a steel wire is often used to ensure stability, which is often silver-plated or copper-plated. A copper wire, sometimes tinned or silver-plated, is often used for thicker cables and offers greater flexibility compared to a steel wire.
As a rule, wires are therefore solid and therefore only slightly bendable, making them best suited for fixed installation. The advantages of a solid wire are generally a lower attenuation value and a higher electrical load capacity, which can increase signal transmission and signal quality.

Several individual wires, twisted together – stranded wire:
A stranded wire is an inner conductor with many very thin individual wires. Some of these are only a fraction of a millimetre in diameter and are braided together to form a single inner conductor. This ensures a particularly high degree of flexibility, which increases with the number of interwoven individual wires. Stranded wires are often used in moving applications where the cable is repeatedly bent.
Another advantage of stranded conductors over wires is the reduced risk of conductor breakage. The cable can still be used even if a certain number of the individual wires are broken.
Summary: The correct choice of inner conductor is heavily dependent on the intended application of the cable. However, this should not be the only decisive factor in choosing the right cable. Other factors such as the material of the outer sheath, the insulation and other components of the cable play an important role.
The promotion of the education sector is a special concern for arnotec GmbH. We have therefore decided to adapt our conditions for universities, colleges and similar institutions. We want to make our contribution to the next generation of researchers and scientific progress.
In addition to a payment term of 30 days net, also for new customers, we offer a special discount of 5% on our entire range of cable assemblies. The pre-assembled coaxial cables from koax24 and the stranded cables from litze24 impress with their high quality workmanship and only the best materials. Even deliveries at short notice can be reliably realized thanks to our numerous express options.
In addition to this discount, we offer special conditions for larger orders of 100 units or more and for tenders. Contact us for more information or for a customized offer.
Corrugated cables with low loss properties, such as the Cellflex® variants, are usually also referred to as semi-flexible cables. In addition to a strong electrical performance, they also have an extremely robust design, which makes them ideal for applications in radio systems. Due to their PE jacket, they can also be used outdoors, where they are used for mobile phone base stations, HD TV and mobile internet, among other things.
A side effect of the special design with corrugated shielding is that this type of cable is only suitable for fixed installation. An application with frequent movement frequency is not compatible with the high bending radius. However, the cables offer excellent technical values, low losses and a high shielding effect.
The new arrival at koax24: Cellflex® corrugated cable
Seit kurzer Zeit führen wir zwei unterschiedliche Cellflex® Wellmantelkabel in unserem Sortiment: das LCF12-50J sowie das LCF14-50J. Beide Kabel sind ab sofort als Meterware erhältlich. Benötigen Sie die Leitungen bereits mit den passenden Steckverbindern konfektioniert? Dann werfen Sie jetzt einen Blick in unseren Online-Kabelkonfigurator. Neben den Wellmantelkabeln finden Sie hier eine große Auswahl an Koaxialleitungen in 50 und 75 Ohm. We have recently added two different Cellflex® corrugated cables to our range: the LCF12-50J and the LCF14-50J. Both cables are now available by the meter. Do you need the cables already assembled with the appropriate connectors? Then take a look at our online cable configurator. In addition to the corrugated cables, you will also find a large selection of coaxial cables in 50 and 75 Ohm.
If you have any additional requirements that go beyond our range, please do not hesitate to contact us.
Our product range includes both connectors and coaxial cables from Amphenol Times Microwave Systems. The high-quality LMR cables are particularly noteworthy. In our range you will find the LMR-100A, LMR-195, LMR-200, LMR-240, LMR-400 and LMR-600, some of which are also available in various designs, which we have summarized for you in the following overview.
Regular LMR Cables:
The standard LMR cables are suitable for a wide range of applications, for example for measurement technology, laboratory use, audio and radio applications, broadband communication and in the automotive sector. The cables can be used reliably at frequencies up to 6 GHz and, thanks to their PE outer sheath, both indoors and outdoors. In our online shop you will find numerous connectors that are compatible with the various LMR cables, but you can also get them pre-assembled according to your wishes using our online cable configurator.
Ultraflex (UF):
The Ultraflex version of the LMR cables is suitable for moving applications with smaller bending radii than regular cables thanks to its stranded inner conductor. They can also be used outdoors and have low-loss characteristics. Our product range includes the UF versions of the LMR-195, LMR-240 and LMR-400.
Fire resistant (FR):
The LMR-FR cables have a fire-resistant polyethylene sheath and comply with the MIL-C 17F standard. They are suitable for installation inside buildings. We stock the FR versions of the LMR-100A, LMR-195, LMR-240, LMR-400 and LMR-600.
Direct Burial (DB):
The waterproof LMR-DB variant has a UV-resistant outer jacket and a waterproof structure. Due to their high weather resistance, these cables are particularly suitable for outdoor use. We have the LMR-400-DB in our range.
Since we always want to offer our customers only the best quality and at the same time affordable prices, we have launched our own brand arnoflex together with a European cable manufacturer.
Our arnoflex cables are a low-cost alternative to well-known branded cables, with equivalent and in some cases better mechanical and electrical properties.
The arnoflex 214 LSNH can be ordered by the meter or pre-assembled with connectors in our online shop.
The table below compares the values of the RG214/U and arnoflex 214 LSNH cables. What is particularly worth mentioning here is that the arnoflex 214 has better attenuation values, is suitable for lower temperatures and is halogen-free. In addition, the RG214/U is double shielded, whereas the arnoflex 214 is triple shielded.
arnotec GmbH has moved! Since mid-September the
supplier for the electrical industry has been in its new premises
in Grünhutstraße 7 in Karlsruhe-Knielingen.
For years, arnotec, whose brands also include koax24, has been experiencing steady growth – also in terms of the number of employees. For this very reason, we reached our limits with the capacity of the former offices and production hall. A move became unavoidable and in mid-September the time had finally come: after the production had already moved into the new hall, the administration also moved into the new offices.
The move to our new company building went almost unnoticed by our customers and completely smoothly. Thanks to the perfect planning and great support of all employees, it also went almost without a production stoppage.
A huge “THANK YOU” goes to all employees, helpers and supporters for this great team effort!
Our customers can look forward to the continued excellent quality of our products and the best service from our staff, who can be reached at the same telephone number and e-mail address as before.
