Leakage Current Tracking Tester is designed to evaluate the tracking resistance of solid electrical insulating materials under humid conditions. By applying voltage across a specimen and dripping a conductive liquid, the tester simulates the electrical stress and evaluates the material's resistance to surface tracking. The equipment is widely used in electronics, plastics, electrical, and automotive industries for quality control and performance assessment of insulating materials and electrical components.
Application
The Tracking Tester is suitable for testing the tracking resistance of various solid insulating materials, including:
Electronics Industry: Evaluates tracking performance of electrical components, circuit boards, and insulating materials.
Power Industry: Assessment of electrical insulating materials for cables, switches, transformers, and related equipment.
Plastics: Testing of plastic products, insulating coatings, and electronic plastic housings.
Automotive Industry: Evaluation of tracking resistance of automotive electrical systems, batteries, and electronic components.
Construction Industry: Testing electrical materials for building applications, including cables, distribution boxes, and sockets.
Household Appliances: Insulation performance testing for wires, batteries, plugs, and other electrical components.
R&D and Quality Control: Verification of new materials and ongoing product quality monitoring.
Standards
The tester complies with the following national, industry, and international standards:
GB/T 4207-2003: Determination of comparative and proof tracking indices of solid insulating materials under wet conditions
IEC 60112: Test methods for electric strength and tracking resistance of solid insulating materials
UL 746A: Plastic Materials – Short Term Property Evaluations
