The HCAI-2 High-Current Arc Ignition Test System is a LISUN test device designed specifically to evaluate the arc ignition resistance of insulating materials and solid combustible components in electrical and electronic equipment. It simulates the high-current arcing scenario generated by electrical equipment failures. By accurately striking an arc 200 times on the sample surface, the material is determined to ignite, thereby evaluating its resistance to high-current arc ignition. The HCAI-2 integrates a stable arc generation system, a precise arc counting module, and a reliable combustion monitoring device, efficiently replicating standard test conditions. It is widely used in the R&D, production, and quality inspection of lighting, low-voltage electrical appliances, household appliances, information technology equipment, and other industries. It also meets the performance assessment needs of the insulation materials and engineering plastics industries, making it a crucial testing tool for ensuring the safe operation of electrical and electronic products and preventing electrical fires.
