Product Description Product DescriptionArc Resistance Tester NDH-15KNDH-15KImmerse yourself in the realm of 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 is a pinnacle of excellence in its field.,it's sthe quintessential choice for analyzing electrical insulation materials, including plastics, films, resins, mica, ceramics, glass, insulating paints, and a multitude of other insulating materials, ensuring superior arc resistance evaluation. It is also an indispensable asset for product testing and exploring the electrical properties of innovative materials.Application areaPCBPhotovoltaic Film MaterialsPTFE, ABS, Nylon, and Other PlasticsFilm MaterialInsulating PaintMica MaterialsCeramic, Glass Fiber, etc. Detailed PhotosFunctional featuresOur 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.Product ParametersArc on/off time errorAll program segments are superior±1msVoltage regulator capacity1kVARated test voltage12.5kVMaximum test voltage15kVElectrode pressure on sample(0.5±0.05)NElectrode materialTungsten barsTest voltage accuracy<1.5%Current measurement accuracy<1.5%Distance between electrodes(6.35±0.1)mm(IEC) (6.0±0.1)mm(ASTM)Ambient temperature(23±2)oCAmbient humidity(50±5)%Power supply220V±5% 50Hz 10AProgram segmentArc current mAArc on&off time /sDuration of each program segment/sTotal test time/sIEC 61621ASTM D4951101/8son 7/8s off1/8son 7/8s off60602101/4s on 3/4s off1/4s on 3/4s off601203101/4s on 1/4s off1/4s on 1/4s off60180410Continuous power on60240520Continuous power on60300630Continuous power on60360740Continuous power on60420Note:Ensure all instruments and equipment are properly grounded, maintaining grounding resistance at ≤4Ω. ,The Supply and Demand parties agree that the supplier will provide technical specifications while the demander is responsible for establishing their own grounding system.Exhibition photos
