  • 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.

    Operation:
    1. Electrical and Electronic Products Industry
    1.1 Equipment and Component Testing
    • Lighting Equipment: Test the insulation housing of LED drivers and the plastic components surrounding lamp terminals to verify that they do not ignite when exposed to arcing, thereby preventing lamp fires.
    • Low-voltage Electrical Equipment: Evaluate the insulation housings and terminal insulation sleeves of circuit breakers and contactors to ensure arcing does not ignite components, thereby ensuring the safety of low-voltage power distribution systems.
    • Household Appliances: Inspect the motor insulation and control panel plastics of washing machines and refrigerators to prevent equipment damage caused by arcing due to internal circuit faults.
    • Information Technology Equipment: Verify that the insulation materials of power modules and combustible components surrounding the motherboard of computer hosts and servers meet the safety requirements of GB/T 4943.1-2022.
    1.2 Electrical Connector and Accessory Testing
    • Tests the insulation housings of terminal blocks, plugs and sockets, and cable insulation (e.g., PVC, XLPE) to ensure arcing does not ignite the connectors and prevent fires in the wiring.
    2 Insulation Materials and Engineering Plastics Industry
    • Evaluates the arc ignition resistance of materials such as insulating paper, epoxy glass cloth, PA66, and PC. This provides a basis for selecting components for electrical and electronic products, optimizes material flame retardant formulations, and enhances overall product safety.
