Product No: LS-B25
The LS-B25 solid insulation dielectric strength testing device is used to test the dielectric strength of various insulating materials and verify whether their insulation performance meets standards under specified voltage conditions. This device uses a specific type of test probe in conjunction with an insulating base to place the test sample at a suitable test position and apply the corresponding test voltage. It simulates the electric field environment of the insulating material in actual use, detecting whether insulation failure such as edge breakdown will occur. During the test, different test configurations can be adapted to meet the testing needs of different types of insulating materials, providing objective evidence for the quality judgment and performance verification of insulating materials, and ensuring that related equipment operates reliably due to its insulation performance, thus avoiding potential safety hazards.
