Arc Resistance Tester NDH-15K
NDH-15KStep into a world of unparalleled precision testing with our exceptional Arc Resistance Test System, thoughtfully designed to cater to the intricate demands of electrical insulation material scrutiny. This advanced equipment stands as a testament to supreme excellence in its specialized domain.,it'sthe ultimate selection for the in-depth analysis of electrical insulation materials. From plastics, films, resins, and mica to ceramics,glass, insulating paints, and an extensive array of other insulating materials, it guarantees a superior arc resistance evaluation,making it an indispensable tool for rigorous product testing and the exploration of electrical properties in pioneering materials.
Our state-of-the-art insulation materials display extraordinary resistance against degradation from high-voltage arc activity. The process typically starts with a standard arc flame that causes carbonization on the material's surface, which progresses to a conductive state. The precise time taken for the arc to extinguish is meticulously recorded in seconds. Two tungsten electrodes are strategically positioned at a specified interval on the sample plate,where the arc begins to occur intermittently, eventually shortening to form a continuous arc as the current escalates. The subjected material endures increasingly severe arc conditions until it culminates in failure. Resistance to arcs is crucial for insulating materials employed in high-voltage switches or low-voltage high-current switches, where arcing is a regular occurrence during operation. Only materials exhibiting extraordinary arc resistance qualify.
In the world of electrical and electronic devices, insulating materials exposed to high-voltage, low-current arc discharges reveal unique surface damage patterns near the arc. Such discharges lead to local thermal and chemical degradation and corrosion, ultimately forming a conductive path on the material. Once this conductive channel emerges, the material is considered to have failed the test.
Our Arc Resistance Tester adheres to distinguished standards like GB1411, IEC61621, ASTMC495, UL746A, making it a vital instrument for executing simulated safety testing protocols.
Meticulously crafted to comply with stringent standard requirements, the arc resistance tester is equipped with detailed electrical schematics and high-accuracy electrodes.
