Product Description Product DescriptionArc Resistance Tester NDH-15KNDH-15KImmerse yourself in the world of precision and accuracy with our Arc Resistance Test System. This masterpiece, designed to perfection, caters to the stringent requirements of evaluating electrical insulation materials. Truly, this state-of-the-art equipment stands as a beacon of excellence in its domain.,it's sthe ultimate choice for analyzing electrical insulation materials, encompassing plastics, films, resins, mica, ceramics, glass, insulating paints, and a diverse array of other insulating materials, ensuring superior arc resistance evaluation. It becomes an invaluable asset for product testing while probing the electrical properties of cutting-edge materials.Application areaPCBPhotovoltaic Film MaterialsPTFE, ABS, Nylon, and Other PlasticsFilm MaterialInsulating PaintMica MaterialsCeramic, Glass Fiber, etc. Detailed PhotosFunctional featuresOur innovative insulation materials showcase extraordinary resistance to degradation from high-voltage arc activities. Conventionally, an arc flame sparks carbonization on the surface, rendering it conductive. This process is meticulously timed in seconds. Employing two tungsten electrodes set at a precise distance,the arc starts intermittently, progressively shortening until forming a continuous arc as current surges. The material endures increasingly harsh arc conditions, culminating in eventual failure. Arc resistance is crucial for insulating materials used in high-voltage switches or low-voltage high-current switches that regularly encounter arcs. Only materials with exceptional arc resistance meet the standard.In the realm of electrical and electronic devices, insulating materials exposed to high-voltage, low-current arc discharges demonstrate distinct surface damage variations near the arc. These discharges induce localized thermal and chemical deterioration, creating a conductive path. Once a conductive channel is formed, the material is considered to have failed the test.The Arc Resistance Tester adheres to standards such as GB1411, IEC61621, ASTMC495, UL746A, making it vital for executing simulated safety testing procedures.Designed to meet stringent standard requirements, the arc resistance tester is equipped with detailed 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 adequately grounded, with grounding resistance maintained at ≤4Ω. ,The Supply and Demand parties agree that the supplier will provide technical specifications while the demander is tasked with setting up their own grounding system.Exhibition photos
