Functional features Our cutting-edge insulation materials exhibit remarkable 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 faces increasingly severe arc conditions, leading to eventual failure. The resistance to arcs is essential for insulating materials in high-voltage switches or low-voltage high-current switches, regularly encountering 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 deterioration 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 standards such as GB1411, IEC61621, ASTMC495, UL746A, making it an essential instrument for conducting simulated safety testing procedures.
Engineered to meet rigorous standard requirements, the arc resistance tester features comprehensive electrical schematics and high-precision electrodes.
