What is special about twistable cables?

Marco Thull | 8. July 2019

The structure of the cable is special. When +/- torsion occurs, the cable shortens or becomes longer internally. Similar to a towel being wrung. In the case of cores, for example, this is achieved in that the stranding contains elements that compensate for the movement of the cores and act like a shock absorber. Vote […]

What is a “star quad structure”?

Marco Thull | 8. July 2019

A star quad structure is used as an alternative to a cable with two twisted pair elements. Four cores are stranded together in a criss-cross pattern, whereby the respectively opposite cores form a core pair. This structure prevents so-called crosstalk. Vote Up +0 Vote Down -0You already voted!

Why are 7-core cables in an energy chain not so good?

Marco Thull | 8. July 2019

7-core cables are problematic, above all over long distances and in small bend radii. The problem is the large stranding circumference that mainly occurs in the case of 7-core cables with cross sections of more than 1.0 mm. Due to the push/pull forces that act on the cores when the cable is bent, the cores […]

Why should I prefer a “star quad structure” for movement in a linear chain?

Marco Thull | 8. July 2019

A normal twisted pair cable without a star quad structure would have to have very many filler elements in order to end up with a round cable shape. These filler elements would make the interior structure of such a cable very unstable and the cores would move about a lot in the cable. As a result, […]

What is the characteristic wave impedance and what does it mean?

Marco Thull | 8. July 2019

The characteristic wave impedance describes the propagation characteristics of a signal in a cable. Put simply, the characteristic wave impedance indicates how high the impedance is that a signal has to overcome when it is propagated in a cable. Vote Up +0 Vote Down -0You already voted!
