CYKY kabely pro domovní rozvody - Vliv teploty na odpor žil

Abstract

The body of this diploma is experimentally pass judgment on agreement real values resistivity copper conductors of cables CYKY with tabular values and experimentally determines resistance conductors in depending on temperature. In theoretic parts I acquaint reader with CYKY cable in common theory, with coppers and her features, with electric resistance and his calculation, further then methods of metering with will determine electric resistance and resistivity. In this part are also takes in reference norms to all questions diploma. In parts personal experimental metering I show in method that the I used for metering, used apparatus and making and description workplaces, whereon I measured. Further then here are mentioned results personal metering and final estimation all metering.
