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!

Do cables become longer in hanging applications?

Marco Thull | 8. July 2019

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 […]

What is the significance of the three aspects relating to bend radius and temperature?

Marco Thull | 8. July 2019

Three different factors are related to the bend radius for cables. the bend factor in use of a fixed cable the bend factor in use of a flexible cable the use in a linear chain The temperature information of the individual cable families relates to three different scenarios: fixed installation, flexible movement and movement in […]

Is there a difference between control cables and motor cables?

Marco Thull | 8. July 2019

The basic difference is to be found in the voltage class of the cores in the cable. Control cables usually have a voltage class of 300 V/500 V and motor cables have a voltage class of 600 V/1000 V. Vote Up +0 Vote Down -0You already voted!
