Product No: TTC-2
The TTC-2 High-Voltage Tracking Tester is a high-precision tester designed by LISUN specifically for testing the tracking and erosion resistance of solid insulating materials. It simulates the tracking risk of insulating materials under power-frequency high voltage in harsh environments (such as humid and polluted conditions). By applying high voltage and dripping liquid contaminants, it assesses the material’s tracking resistance. Widely used in R&D, production, and quality inspection in the electrical and electronics, new energy, and rail transit sectors, it is a crucial testing tool for ensuring the safe use of insulating materials during high-voltage operation.

Feature:
1. Electrical and Electronic Insulation Materials Industry
• Insulator Testing: Testing the tracking resistance of porcelain and composite insulators used in power systems. This simulates the risk of high-voltage leakage in a humid and polluted outdoor environment to verify whether the material will produce tracking at 6000V, thereby preventing insulator breakdown and grid failure.
• Electrical Insulation Component Testing: Testing the insulation casings of contactors and circuit breakers (such as PA66+GF30 engineering plastics) and motor winding insulation paper. This testing is conducted through AC 1000-6000V voltage tests to assess their corrosion resistance under high voltage and ensure compliance with the safety requirements for electrical insulation materials in GB/T 6553-2024.
2 New Energy Industry
• Power Battery Insulation Component Testing: Verifies the tracking resistance of internal insulation separators (such as epoxy glass cloth panels) and high-voltage wiring harness insulation layers under high voltage (DC 3000-6000V) in power battery packs. This prevents insulation failure caused by electrolyte leakage and contamination, ensuring battery pack safety.
• Photovoltaic Module Testing: Tests the internal insulation gaskets and junction box insulation materials of photovoltaic inverters. Tests are conducted using the step-by-step voltage method to verify the material’s tracking resistance, simulating outdoor high-temperature and high-humidity environments. This test meets the stringent requirements of IEC 60587:2022 for insulation materials in new energy equipment.
3. Rail Transit and High-Voltage Equipment
• Rail Vehicle High-Voltage Component Testing: Testing the insulation layers of high-voltage cables and pantograph insulators in subways and high-speed railways, evaluating their tracking resistance at voltages of AC 2500-6000V. This prevents tracking caused by dust and moisture in the rail environment and ensures the stability of the vehicle’s power supply system.
• High-Voltage Switchgear Testing: Testing the insulating materials of high-voltage switchgear, including insulating partitions and bushings. Using a constant voltage method (e.g., applying AC 6000V), we verify the material’s corrosion resistance under long-term high voltage conditions, ensuring compliance with power industry safety standards for high-voltage equipment insulation.
4. Material R&D and Quality Inspection
• Material R&D Verification: During the new product development phase, insulation material companies (such as silicone rubber and engineering plastics manufacturers) use this device to test the tracking resistance of different material formulations (for example, adjusting the amount of flame retardant added) and optimize material composition to improve high-voltage leakage resistance.
• Third-Party Testing and Certification: Testing organizations such as SGS and CQC use the TTC-2 to provide companies with insulation material compliance test reports based on UL 746A:2023 Clause 34 and IEC 60587:2022, helping products obtain international certifications such as CE and UL and enter the global market.
