GREELEY AAAC Conductor Cable
Raw Material Test
Raw material testing for the Greeley AAAC Conductor Cable adheres to ASTM B398. Aluminum alloy ingots (6201) are analyzed for Mg (0.6-0.9%), Si (0.5-0.9%), and impurities using optical emission spectrometry. Wires undergo conductivity (53% IACS min), tensile (295 MPa min), and elongation (3.5% min) tests with machines. Samples face heat treatment verification at 180°C and microstructure analysis via microscopy for grain uniformity. Corrosion resistance is assessed in humid chambers. The structured process: supplier batch review, random sampling, physical testing (diameter tolerance), mechanical verification (after aging), chemical confirmation, accelerated corrosion trials, and approval stamp.
Process inspection
Process inspection in Greeley AAAC Conductor Cable manufacturing follows ASTM B399. Wire drawing controls diameter and ovality with calipers. Solution heat treatment furnace logs temperature (500-550°C) and quench rate for alloy hardening. An aging oven maintains 180°C for the T81 temper. The stranding machine verifies 61-wire configuration, lay length (12-16 times diameter), and compression. Surface finish and printing durability are assessed. Critical steps: pre-production compound verification, line speed/temperature control, real-time dimension scanning, hot set sampling for crosslinking uniformity, and immediate corrective actions for defects.
Finished Product
Completed Greeley AAAC Conductor Cable is subjected to strict acceptance tests. Mandatory routines: DC resistance, high-potential AC test, insulation thickness, sheath integrity, and armour continuity if applicable. Mechanical endurance via compression, impact, and penetration tests. Heat shock and flame propagation evaluations follow. The sequential process: reel sampling, conditioning, gradual load/voltage application, timed exposure monitoring, recovery inspection, property re-measurement, and documentation. Additional checks cover ovality and weight. Passing all confirms the Greeley AAAC Conductor Cable's mechanical robustness, electrical reliability, durability, and suitability for direct burial low-voltage networks.
