High voltage resistance tester is a professional equipment used to test the breakdown strength of solid materials. This device is equipped with high-precision current and voltage sensors, with multiple protection functions such as overcurrent and short circuit, and supports remote wireless Bluetooth control. In addition, the instrument is capable of real-time drawing of test curves, recording and analyzing test data, and complies with multiple international standards such as ASTM D149.
Suitable for testing the breakdown voltage, breakdown strength, and voltage resistance of solid insulation materials such as insulation coatings, resins and adhesives, impregnated fiber products, and laminated products under power frequency voltage.
Input voltage | AC 220V |
Power | 3KVA below 50kV |
Output voltage | AC 0-50kv |
Boosting rate | speed of 0.1kV/s0.2kV/s0.5kV/s1.0kV/s2.0kV/s3.0kV/s5.0KV/s |
1. Breakdown voltage (V) | Apply a power frequency voltage to the sample by continuously and uniformly boosting it, and maintain the voltage value at which the sample breaks down, expressed in kV. |
2. Breakdown strength (E) | The quotient of the breakdown voltage value of the sample and the average thickness of the sample between the two electrodes, measured in kV/mm. |
The device is equipped with multiple protection circuits such as overcurrent, overvoltage, undervoltage, short circuit, and leakage. If any abnormalities occur during the experiment, the high voltage will be automatically cut off.
The experiment is conducted in a closed test box, and the input terminal of the high-voltage transformer cannot be powered when the door is open, which reduces the risk of electric shock from a design perspective.
√ . Supports 7 adjustable boost speeds ranging from 0.1kV/s to 5.0kV/s, and different materials can flexibly choose the appropriate boost speed.
√ .It can complete three testing modes: "breakdown test", "withstand voltage test", and "gradient withstand voltage test" to meet different standard requirements.
√ .Equipped with specialized computer software, experimental data is automatically collected, saved, and printed without the need for manual recording.
Suitable for testing the breakdown voltage and breakdown strength of solid insulation materials such as insulating paint, resin, laminated products, mica, plastic, film, ceramics, glass, etc.
Commonly used in daily testing in quality inspection institutes, material laboratories, wire and cable factories, and insulation material production enterprises.
⚠️ Safety note: This equipment generates high voltage. Operators must be trained. A supervisor should be present during testing. The equipment casing must be properly grounded.
