Enamelled Round Wire Test Room Softening Breakdown Tester IEC60851
Softening breakdown tester KDZD-JC is a new type of coated round wire testing instrument designed according to GB/ T40746-2008 and idtIEC60851-6:2004 standards. The instrument adopts thermocouple temperature measurement, digital temperature controller automatically adjusts and displays the test temperature, and the test part adopts integrated circuit. Test process automatic control. The instrument is small in size, simple in operation, safe and reliable, high in sensitivity, good in repeatability and accurate in test results. It is suitable for inspecting the performance of enamelled round wire manufacturers and enamelled wire users.

Working principle
The instrument is mainly composed of current detection circuit, time control circuit, power supply, motor drive circuit and heating temperature measurement. The sample is heated to a specified temperature through a heating tube, and then both voltage and load are applied to the sample. When the 5±0.5mA current passes between the samples, the instrument will alarm the unloading and decompression at the same time. If the sample is not broken down within the set test time, (that is, the current between the samples within the set time is less than (5±1) mA, the instrument does not alarm, but unloading and decompression).
