Attenuation-Based Cable Design for High-Quality Manufacturing

Abstract

The original design model for defining the attenuation of manufactured cables was derived and fitted to experimental data. The model relationship connects attenuation with some parameters of cable design and testing: copper wire, aluminum, and insulation thicknesses, cable impedance, test frequency, and lay length. Defined expression was used for Monte-Carlo simulation of the cable attenuation prediction. With developed MATLAB program, a special graphical user interface was created. After assigning the desired parameters, this interface generates a plot with distribution of the attenuation values and required attenuation limit, and outputs defined mean attenuation, its 98% error, and numbers of values that get in and out of the limiting value. Data of calculations were verified by experiments and reveal good concurrence with the actual data. The realized fitting and simulation procedure, together with developed programs and created interface can be used as compact tool for designing cables with optimal parameters.
