Porovnání uvolňovaného tepla z elektrických kabelů vedených volně a v lištách

Abstract

This bachelor thesis is devoted to the assessment of flammability and heat release rate of CYKY 3*1.5 and 3*2.5 electrical cables, which are widely used all over the world. The thesis is divided into theoretical and practical. In the first part, the classification of cables, their construction and material composition, description of electrical installations in buildings, their conduction possibilities and electrical fires are also mentioned. The next part deals with fire characteristics according to the ISO 5660-1 method, and the conical calorimeter on which the measurements were made is also presented. The practical part is devoted to experimental measurements of loose and rail-running electrical cables. Finally, the measurements are evaluated and the results are compared with each other.
