Synthesis of constructive-technological decisions of regulation of working capacitance of cables of industrial networks

Introduction. Over the past 10 years, number of industrial networks has more than doubled. At physical level, all technology are based on twisted pair. Purpose. Synthesis constructive-technological decisions regulation electric capacitance insulated conductor at a stage manufacturing pair cables networks. Methodology. The method secondary charges to determine by varying thickness solid and foamed polyethylene insulation. Practical value. Effective is provided basis obtained dependencies effective dielectric constant, tangent loss angle degree foaming protective film two-layer porosity 40 %, constant decreases 25 – 33 electrical 20 %.
