Arc Resistance Tester NDH-15K
NDH-15KDive into the world of precision with our groundbreaking Arc Resistance Test System. This remarkable instrument is expertly designed to meet the demands of rigorous testing of electrical insulation materials. As a pinnacle of high precision, it stands out as a beacon of excellence in the field, setting new standards for accuracy and reliability.,it's san ideal choice for meticulously analyzing electric insulation materials. Including plastics, films, resins, mica, ceramics, glass, insulating paints, and other materials, it ensures superior arc resistance evaluation. This makes it indispensable in product testing and researching new materials' electrical properties., it also serves as a crucial tool in the testing and research landscape of new material properties, focusing on their electrical viability and endurance.
Our state-of-the-art insulation materials demonstrate exceptional resistance to degradation from high-voltage arc activity. Typically, a standard arc flame induces carbonization on the material's surface, which becomes conductive over time. The duration taken for this process to occur is measured in seconds. By employing two tungsten electrodes positioned at a precise distance on the sample plate,initially, the arc is intermittent. This gradually evolves into a continuous arc with heightened current, subjecting the material to increasingly harsh conditions until failure occurs. Arc resistance is paramount for insulating materials used in high-voltage switches or low-voltage high-current switches, as these are frequently exposed to arcs during operation. Materials boasting exceptional resistance are the ideal choice.
When incorporated into electrical and electronic devices, insulating materials subjected to high-voltage, low-current arc discharges exhibit notable variations in surface damage near the arc. Such discharges precipitate localized thermal and chemical breakdown and corrosion, forming a conductive path. Once this path forms, the material is considered to have failed the test.
The Arc Resistance Tester is meticulously aligned with standards including GB1411, IEC61621, ASTMC495, and UL746A. It stands as an indispensable instrument for simulated safety testing procedures, ensuring compliance and reliability.
Crafted to meet stringent standard requirements, the arc resistance tester incorporates detailed electrical schematics and precision electrodes, ensuring unparalleled accuracy and performance.
