WDY-T: 15KV, 5 groups simultaneous boost voltage; WDY-20: 20KV, 5 groups boost voltage in turn /WDY-30: 30KV single group test.

1) Function: for testing the voltage breakdown performance and voltage withstanding performance of winding wire insulation at room temperature; can cooperate with plexiglass tank to complete dynamic or static voltage breakdown performance test and voltage withstanding performance under brine or glycerol；

2) Comply with the latest IEC, GB, JIS and NEMA standards；

3) Breakdown current is 5±0.5mA; (5 mA - 10 mA switching function can be customized)；

4) The highest test voltage≥15KV; (20KV or 30KV can be customized)；

5) Voltage boost rate: (500 ± 50) V/S;

6) The error of test voltage indication is less than 2.5%；

7) High voltage wire connects to the plexiglass brine tank linkage；

8) Dimensions of plexiglass tank: 1200×800×700mm；

9) Withstand time: 1s to 99min 59s；

10) During the test, breakdown voltage can be tested when the sample is stationary or withstand voltage when the sample moves；

11) When static breakdown voltage test is carried out, the wire sample with effective distance of 1 meter is immersed in brine water (or glycerol), and the automatic boost (maximum 15KV) is started by pressing one button. The breakdown value is recorded automatically in the voltmeter；

12) During the moving withstand voltage test, the tester do automatic take-up (30m) with take-up speed 16m/min, withstand voltage can be set 0-15KV; after voltage is broken down, the tester is automatic step-down and stop take-up, saving the voltage value. If no breakdown occurs within 30 meters, the voltage will automatically drop and the test ends.
