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 […]
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!
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 […]
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!
Yes, theoretically. However, this effect is irrelevant and can readily be ignored. It is much more important that the tensile force acting on cables in vertical and hanging applications does not exceed a maximum level. The maximum permissible tensile force for standard cables is 15N/mm² cross section of the main cores. Due to a special […]
