What does the colour code according to DIN 47100 say?

Marco Thull | 8. July 2019

The colour code DIN 47100 is used to differentiate cores and contains a defined sequence of colours of the core insulation. Especially in the case of cores with a cross section less than 0.5 mm². With cores of this thickness, it is difficult to detect numbering, which is the alternative way of marking cores. Vote […]

Why do some BUS cables have foam core insulation (FOAM)?

Marco Thull | 8. July 2019

Foam core insulation ensures that there is a defined distance between the individual cores but the material constant of the insulating material is similar to that of air and not of plastic. If normal core insulation were to be used, it would not be possible to adhere to the BUS specifications. Vote Up +0 Vote […]

How is the right strain relief for cables to be selected?

Marco Thull | 8. July 2019

The right strain relief is selected on the basis of the thickness, the place and the functionality of the application. When the position of the cable is set, it must be ensured that the cable is laid in the neutral fibre in the chain. Vote Up +0 Vote Down -0You already voted!

What influences the capacitance of a cable?

Marco Thull | 8. July 2019

The capacitance between the cores is influenced by the core insulation (material), the voltage classes (wall thickness of the core insulation) and by the material of the insulation (material constant). With regard to the capacitance in relation to the shield, the situation is similar but the position of the core in relation to the shield […]

What is the NVP value and what do I need it for?

Marco Thull | 8. July 2019

The NVP value is the time that a signal needs to pass through a cable compared to the speed of light. This is primarily of interest for bus cables and is determined by their structure. Vote Up +0 Vote Down -0You already voted!
