The insulation material voltage breakdown tester is controlled by a computer and completes the power frequency voltage breakdown and power frequency withstand voltage tests of the insulation material through man-machine dialogue. It is suitable for testing the breakdown voltage, breakdown strength, and withstand voltage of solid insulating materials (such as insulating paints, resins, and adhesives, impregnated fiber products, laminated products, mica and its products, plastics, film composite products, ceramics, and glass) at power frequency voltage.

1. Siemens CPU central unit processor has the highest and most stable acquisition accuracy;
2. Wireless Bluetooth control gets rid of the distance problem and is more convenient to use when separating between humans and computers. Unique in China, better protecting personnel safety;
3. Bidirectional voltage and current interference suppression technology to prevent the danger of loss of control and burning of communication ports caused by current interference at the time of breakdown;
4. The new software has a self check function and an early warning prompt function, which adds two-way current and voltage judgment, and supports wireless security control. Generally, manufacturers can only rely on voltage detection;
5. Electric leakage protection net is installed inside, and the electric arc automatically relieves pressure;
6. The latest control program in C++provides more accurate results;
7. It is superior to other manufacturers that can only make solids, and our testing machine can make both solids and liquids;
8. Built-in fuse protector, and leakage protector. Overcurrent or overload can effectively burn out the fuse to protect the instrument control and high-voltage parts and facilitate replacement.
