Arc Resistance Tester NDH-15K
NDH-15KEmbark on a journey into unparalleled precision with our state-of-the-art Arc Resistance Test System, meticulously engineered to meet the exacting demands of evaluating electrical insulation materials. This exemplary high-precision apparatus is a shining beacon of innovation and quality in the realm of electrical testing.,it's sthe quintessential solution for the thorough analysis of electric insulation materials, covering a spectrum that includes plastics, films, resins, mica, ceramics, glass, insulating paints, and numerous other insulating substances, delivering superior evaluation of arc resistance.Moreover, it emerges as an indispensable asset for product testing and pioneering research into the electrical properties of novel materials.
Our premium insulation materials are renowned for their exceptional resilience against degradation typically caused by high-voltage arc activity. A standard arc flame usually induces surface carbonization on the material, turning it conductive. The duration for the arc cessation is meticulously recorded in seconds. Utilizing two expertly spaced tungsten electrodes on the sample plate,initial arc activity is intermittent, gradually progressing to a continuous arc as current intensifies. Over time, the material withstands increasingly severe arc conditions until eventual failure. Arc resistance is a critical factor for insulating materials used in high-voltage or low-voltage, high-current switches, which frequently endure arcs during operation. Materials exhibiting outstanding arc resistance are essential.
Incorporated within electrical and electronic devices, insulating materials facing high-voltage, low-current arc discharges demonstrate distinct surface damage near the arc. These discharges lead to specific thermal and chemical degradation, potentially forming conductive channels on the material, signaling test failure once a conductive path is established.
The Arc Resistance Tester complies with recognized standards such as GB1411, IEC61621, ASTMC495, UL746A, thus making it an essential tool for conducting simulated safety testing procedures with precision and reliability.
Manufactured in accordance with rigorous standards, this arc resistance tester features intricate electrical schematics and precision-engineered electrodes for optimal performance.
