1. Surface treatments such as tin plating and pickling are used, offering advantages like strong oxidation resistance, strong corrosion resistance, and good electrical conductivity. 2. High-quality annealed materials are used to optimize the material and its crimping performance, ensuring a firm crimp; the mechanical tensile load test has obtained a test report from the National Center for Quality Supervision and Testing of Safety Performance of Electric Power Equipment Products, with the test basis: GB/T 14315-2008. 3. Advanced automated equipment and production processes are adopted, resulting in precise and stable product dimensions. 4. Made from high-quality T3 or higher-grade copper materials, with a copper content of ≥99.7%, providing good electrical conductivity with a conductivity rate of no less than 86% IACS. The copper raw materials comply with the national standard: GB/T 5231-2001.
