Learn MoreWithin industrial electrical engineering, selecting the appropriate wire cross-section is critical. The 8mm² Flexible Copper Stranded Wire represents an optimized gauge designed for high current-carrying capacity paired with dynamic mechanical stress resistance.
Unlike rigid solid conductors, a flexible stranded conductor is engineered by twisting multiple fine strands of high-purity copper (often between 0.10 mm to 0.20 mm in single-filament diameter) around a central core. This layout dramatically enhances mechanical bending parameters, prevents structural work hardening, and extends the operational life of connections subjected to constant movement or thermal expansion cycling.
Zhejiang Xingma Copper Industry Co., Ltd. designs and manufactures these components utilizing T1/T2 grade electrolytic copper. This guarantees a copper purity level exceeding 99.9%, minimizing electrical resistivity and optimizing IACS (International Annealed Copper Standard) values to nearly 100%.

Get answers to common technical queries about 8mm² flexible copper stranded wires.
The ampacity of an 8mm² copper wire depends on installation conditions and operating temperature. Typically, in free air at an ambient temperature of 30°C, it carries between 65A to 85A. Enclosed conduits or higher ambient temperatures will reduce this rating, while high-performance jackets (like silicone) allow for higher limits.
Class 5 conductors are designed for flexible installations, using fine wire strands. Class 6 conductors are even more flexible, utilizing a higher count of thinner individual strands (e.g., 0.15mm or 0.10mm) to allow for frequent movement and tighter bending radii without fatiguing.
T2 copper features a minimum purity of 99.9%. This high purity level minimizes electrical resistivity and heat generation under high electrical loads, resulting in optimal efficiency and long-term durability compared to lower-grade recycled options.
We utilize a comprehensive quality control system, including in-house spectral analyzers to verify copper purity, four-terminal resistance testers to measure conductivity, and tensile testers to verify physical durability. Our manufacturing is certified under ISO9001 and ISO14001.
