Heat Resistance Tester For Electrical Lab Training

Heat Resistance Tester - For Electrical Lab Training Heat Resistance Tester For Pliable Electrical Conduits Of Insulating Materials The ability of pliable electrical conduits made of insulating materials to withstand deformation at elevated temperatures is determined by keeping a 100 mm long piece of conduit under a specified load at a temperature of 60ºC for a period of 24 hours and determining the reduction in its cross sectional width because of the loading. The  Heat Resistance Tester for pliable electrical conduits made of insulating materials consists of a metallic frame having a flat platform for placing a 100 mm long piece of conduit on, a horizontal metallic pin of 6 mm diameter held at the lower end of a vertical rod for applying the specified load on the conduit under test, and dead weights for applying the specified load on the conduit under test.   The loading rod is guided inside a vertical brass sleeve so that it can move only along a vertical axis. The weight of the loading assembly is 0.5 kg to enable testing of very light conduits. Additional weights of 0.5 kg and 1.0 kg are provided for testing light and medium conduits. These weights can be placed on a collar attached to the upper end of the loading rod.
