Modeling of metallic cables´ attenuation for extreme temperatures

The transmission parameters of metallic cables and lines, such as attenuation, crosstalk, etc., are significantly influenced by external parameters and conditions, e.g. temperature, external deformations, bending of metallic cable, moisture, glaze ice on the cable, etc. There are already several models to describe some of these phenomena, but these models are usually valid only for a limited range. This article deals with the influence of extreme temperatures (burning) on transmission parameters of metallic cables, especially on its attenuation. This paper contains the description of performed experimental measurement for specific metallic cable and it also presents derived mathematical models and simulations.
