Arc Resistance Tester NDH-15K
NDH-15KImmerse yourself in the realm of unparalleled precision testing with our Arc Resistance Test System, meticulously engineered to meet the exacting demands of electrical insulation material examination. This state-of-the-art equipment stands as a pinnacle of excellence and innovation in its field, ensuring you achieve the highest standards in testing.,it's sthe quintessential choice for thoroughly analyzing electrical insulation materials, including plastics, films, resins, mica, and ceramics. With its unmatched capabilities, it is a top-tier toolics, glass, insulating paints, and a multitude of other insulating materials, ensuring a superior evaluation of arc resistance across the board.. It also serves as an indispensable asset for product testing and delving into the electrical properties of innovative materials.
Our cutting-edge insulation materials exhibit outstanding resistance to degradation caused by high-voltage arc activity. Typically, a standard arc flame initiates carbonization on the material's surface, transforming it until it becomes conductive. The duration for the arc to extinguish is precisely measured in seconds. Utilizing two tungsten electrodes placed at a specific interval on the sample plate,the arc begins intermittently, progressively shortening until it forms a continuous arc as the current increases. The material is subjected to increasingly severe arc conditions, leading to eventual failure. Arc resistance is a critical property for insulating materials in high-voltage switches or low-voltage high-current switches, which commonly encounter arcs during usage. Only materials demonstrating exceptional arc resistance are suitable.
In the realm of electrical and electronic devices, insulating materials exposed to high-voltage, low-current arc discharges exhibit distinctive surface damage variations near the arc. These discharges cause localized thermal and chemical degradation and corrosion, eventually creating a conductive pathway on the material. Once a conductive channel forms, the material is deemed to have failed the test.
The Arc Resistance Tester is aligned with international standards such as GB1411, IEC61621, ASTMC495, and UL746A, making it an essential instrument for conducting simulated safety testing procedures.
Expertly engineered to meet rigorous standard requirements, the arc resistance tester features comprehensive electrical schematics and high-precision electrodes, offering unparalleled accuracy and reliability.
