Quality Control
2 AWG SPARROW ACSR Conductor Cable
Raw Material Test
The Raw Material Test is the first quality assurance step for the 2 AWG SPARROW ACSR Conductor Cable. Aluminum rods are tested for electrical conductivity, tensile strength, elongation, and chemical composition to ensure efficient power transmission. Galvanized steel core wires undergo tensile strength testing, zinc coating thickness measurement, and corrosion resistance evaluation. Surface condition, dimensional accuracy, and material traceability are strictly verified. Only aluminum and steel materials that comply with ASTM, IEC, and internal specifications are approved for production, ensuring the SPARROW ACSR conductor achieves stable electrical and mechanical performance from the foundation stage.
Process inspection
Process Inspection controls manufacturing quality throughout the production of the 2 AWG SPARROW ACSR Conductor Cable. During wire drawing, aluminum and steel wires are continuously monitored for diameter tolerance and surface smoothness. In the stranding process, aluminum layers are helically applied over the steel core with controlled lay length and balanced tension. In-process inspections verify strand alignment, concentricity, compactness, and overall roundness. These checks ensure uniform structure, consistent conductivity, and reliable mechanical strength before final testing.
Finished Product
The Finished Product Test verifies the final quality of the 2 AWG SPARROW ACSR Conductor Cable. Electrical resistance testing confirms compliance with conductivity requirements. Tensile strength and elongation tests validate mechanical reliability under specified load conditions. Final inspections include dimensional measurement, visual examination of stranding and surface finish, marking verification, and packaging integrity checks, ensuring the conductor is ready for safe transportation and installation.
