KDZD-JC softening and breakdown tester is used to detect the insulation performance of enameled wire 3.00mm and below after the film is softened in the hot state. According to the preset preheating temperature, test time, the instrument automatically completes the preheating, loading and test voltage of the sample. When the test time is reached or the sample is broken down, the load is discharged and the sound and light signal is issued. The instrument uses thermocouple temperature measurement, intelligent temperature control, can automatically adjust and display the test temperature, the test part uses integrated circuit, the whole test process is automatically completed.

1. Automatic test, temperature control, temperature regulation and display; According to the preset temperature and test time, the instrument automatically completes the pre-heating of the sample, adding the load and adding the test voltage. When the test time is reached or the sample is broken down, the load is unloaded, and the acousto-visual alarm signal is issued and the test time and temperature are displayed. The whole test process is automatically completed.
2. Automatic forced air cooling fan, so that the second test can be carried out quickly;

1, experimental voltage: AC100±10V (two samples can test voltage);
2, the difference between the indicated temperature and the actual temperature is less than 2℃; Heating mold size 100x100x70mm Test temperature Room temperature -500℃ can be set, automatic constant temperature; The Angle of intersection between the two lines of the heating mold 90" timing device 120s error +1s
