1)Function: for detecting the voltage breakdown property and voltage resistance of winding wire insulation under room temperature. The instrument can cooperate with a thermal voltage tester to complete thermal voltage breakdown performance test and thermal voltage resistance performance test.

2)Starting with one key, 5 groups of samples can be tested in turn automatically.Each sample is individually recorded for voltage endurance time.

3)Under the test condition, the output voltage is approximately sinusoidal, the peak coefficient is √2 * (1 ± 5%) , and the maximum voltage drop is 2% when the transformer capacity can guarantee the output current of 5 mA .

4)Leakage current detection circuit, breakdown action current 5MA/10MA can be switched .

5)Output voltage: 0～15KV（20KV can be customized）, Frequency:50～60Hz

6)Voltage rising velocity: (20 ± 2) V/S, (100 ± 10) V/S, (500 ± 50) V/S

7)Round and flat wire can be tested (including enameled wire, film wrapped wire, wire wrapped wire).

8)Can be custom-made plexiglass tank under the salt water or glycerin dynamic or static voltage breakdown performance test and voltage resistance performance.

9)Voltage indication error: less than 2.5%

10)Optional settings range of withstand voltage time: 0s～9999s

11)With industrial control screen, can store a number of groups of data, data can be queried.

12)Three testing methods: A, round bar method B, torsion method C, steel ball method

13)Power：1000W

14)Overall dimensions and Weight: L 650mm×W 560mm×H 1660mm,145KG.
