CYKY kabely pro domovní rozvody - Vliv teploty na parametry izolace

Abstract

In the first part of this Dissertation work I engaged general characteristics of CYKY cables and basic parameters, which are determined by producers. The sekond part makes characteristic of materials, which are using as insulative part and electric part of cables. I conside with production of most frequently using insulative material, polyvinyl chloride. In the third part I conside analysis mechanical, thermal and other atribute sof insulating materials and also thein degradation. The basic parameters of insulation, I conside in the fourth part. It treat about capacity, insulating resistence and power loss factor. I also show the brief description assorted method of the measurement these parameters. In the FIFA charter I show brief surveyof referential norms and thein prices. The sixth part makes measurement. I show purposes of work, used instruments and educt ov measurement here. I elaboráte everything to tablets and graphs. In the seventh part I show FEM simulation electrostatic field. It treat about calculation of capacities and intensity of electrostatic field of cables by program „Ansys“. Eighth and ninth part makes summary and conclusion. I show my findings and conclusions, which I attain.
