Abstract

Machines and equipment are characterized by various working conditions, and their parts change temperature depending on the principle of operation or the process being carried out. Wires in such devices should be resistant to high temperatures or insulated from heat sources. Danger of damage to cables due to high temperatures occurs not only in the case of structural faults, but also can occur during testing or diagnostics. Another cause of a fire may be the inflaming of installations during renovation work, for example when gas burners are used. The article presents the results of testing selected cables used in the construction of machines. The resistance to the degree of degradation of non-metallic constituents of conduits as a result of convection of heat was determined and the possibility of ignition of electric wires subjected to direct single flame operation was indicated together with the indication of the burnout section in case of ignition of non-metallic layers of the duct.
