Oil-filled copper terminal blocks

1. Surface treatments include tin plating and pickling. This results in strong oxidation resistance, corrosion resistance, and good electrical conductivity. 2. High-quality annealed materials are used, optimizing material properties and pressing performance to ensure a firm bond. Mechanical tensile load testing has been completed according to the National Electric Power Equipment Product Safety Performance Quality Supervision and Inspection Center report, based on GB/T 14315-2008. 3. Advanced automated production processes ensure precise and stable product dimensions. 4. Made from high-quality T3 or higher copper, with a copper content ≥99.7%, exhibiting excellent electrical conductivity of not less than 86% IACS. The copper raw materials conform to the national standard GB/T5231-2001.
