IEC 62368-1 Clause 5.4.9 Figure 29 Solid Insulation Electric Strength Test Device

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.

Standards:

Specification:
• Test needle mass: 100g ( IEC 62368-1, GB/T 4943.1), 50g (UL 1310) each
• Test needle diameter: 5mm (IEC 62368-1, GB/T 4943.1 ), 6.4mm (UL 1310)each

Typical Applications:

• Insulation material manufacturers test the dielectric strength of solid insulation materials before they leave the factory.
• Information technology equipment manufacturers conduct quality verification tests on insulating components used inside their equipment.
• Third-party testing organizations provide dielectric strength compliance testing services for insulation materials according to relevant standards.
• During the R&D phase of electronic and electrical products, performance evaluations are conducted on candidate insulation materials to screen suitable materials.
• Quality supervision departments conduct random sampling inspections of insulation materials and products containing insulating components circulating in the market.
• Power supply equipment manufacturers conduct dielectric strength tests on the solid insulation structure in their products.
