4 AWG SWAN ACSR Conductor Cable

The Raw Material Test is the first quality control stage for the 4 AWG SWAN ACSR Conductor Cable. Aluminum rods are tested for electrical conductivity, tensile strength, elongation, and chemical composition to ensure efficient current 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 carefully inspected before approval. Only aluminum and steel materials that meet ASTM, IEC, and internal technical requirements are released for production, ensuring the SWAN ACSR conductor achieves stable electrical and mechanical performance from the initial manufacturing stage.

Process Inspection ensures consistent manufacturing quality of the 4 AWG SWAN ACSR Conductor Cable. During wire drawing, aluminum and steel wires are continuously monitored for diameter tolerance and surface smoothness. In the stranding stage, 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 controls ensure uniform conductor structure, stable conductivity, and reliable mechanical strength prior to final testing.

The Finished Product Test confirms the final quality of the 4 AWG SWAN ACSR Conductor Cable. Electrical resistance testing verifies 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 safe for transportation, installation, and long-term operation.
