摘要

介绍。在过去的10年里,工业网络的数量增加了一倍多。在物理层面上,所有工业技术网络都是基于双绞线的。目的。工业网络双绞线电缆制造阶段绝缘导体电容调节结构技术决策的综合。方法。通过改变固体和泡沫聚乙烯绝缘的厚度来确定绝缘导体电容的二次电荷的方法。实用价值。根据得到的有效介电常数、介电损耗角的正切和绝缘导体的电容对发泡程度和两层绝缘保护膜厚度的依赖关系,给出了有效的调节。当孔隙度为40%时,介电常数降低25%,介电损耗角的正切值降低33%,绝缘导体的电容降低20%。

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