Tracking Test Chamber | Leakage Tracking Test Apparatus

The TTC-1 Tracking Tester, a high-precision testing device developed by LISUN specifically for evaluating the tracking resistance of insulating materials in humid or contaminated environments, simulates the scenario in which surface contamination (such as dust and moisture) causes leakage current in insulating components of electrical equipment, leading to tracking corrosion or even breakdown. The device drips a standard contaminating solution (0.1% ammonium chloride solution) onto the surface of the specimen, applies a specified voltage, and monitors the leakage current. The presence of a sustained flame or insulation breakdown determines the material’s Tracking Resistance Index (CTI). This provides critical data support for insulation material selection and product safety design in industries such as electronics and electrical equipment.

The TTC-1 Tracking Tester utilizes a high-precision voltage regulation and current monitoring system, ensuring an applied voltage (100V-600V) accuracy of ±1%. The leakage current monitoring range covers 0-100mA, meeting the testing needs of different materials. Equipped with an automatic dripping device, the dripping rate (30 drops/min±5 drops/min) and dripping volume strictly meet standard requirements, preventing human error. It also integrates flame detection and automatic power-off protection. If the sample continues to burn, the device can quickly cut off the power supply to ensure test safety and data accuracy. It is widely applicable in scenarios such as corporate R&D quality inspection, third-party testing and certification.
