FLINT AAAC Conductor Cable
FLINT AAAC (All Aluminum Alloy Conductor) cables are manufactured in accordance with ASTM B399 and IEC 61089 standards, offering excellent strength, conductivity, and corrosion resistance. With 750 mm² nominal area and 37-strand design, it uses heat-treated aluminum-magnesium-silicon alloy (6201-T81) for enhanced strength (295 MPa min) and conductivity (53% IACS min). Meeting ASTM B398, B399, IEC 61089, and BS EN 50182 standards, this cable handles ampacity up to 1150A at 75°C and voltages up to 33kV. The all-alloy construction avoids bimetallic corrosion, providing better resistance in harsh conditions than ACSR. Reduced weight minimizes sag and installation expenses, supporting longer spans. The Flint AAAC Conductor Cable delivers low electrical losses, high mechanical endurance, and excellent weather tolerance. Flame-retardant variants available. Perfect for urban grids, renewable projects, and coastal setups, it provides cost-effective, low-maintenance power delivery in overhead applications globally, excelling in reliability and lifespan over conventional conductors.

Raw Material Test
For the Flint AAAC Conductor Cable, raw material testing follows 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: receipt inspection, random sampling, physical/mechanical testing (diameter tolerance), chemical verification, accelerated aging trials, and release decision.
Process inspection
Process inspection in Flint AAAC Conductor Cable production involves continuous checks per ASTM B399. Wire drawing monitors diameter and ovality with calipers. Solution heat treatment logs temperature (500-550°C) for hardening. Aging maintains 180°C for the T81 temper. Stranding verifies 37-wire lay (12-16 times diameter) and compression. Surface and marking are assessed online. Critical steps: pre-process homogenization confirmation, parameter stabilization (speed 20m/min), in-line tensile sampling, defect scanning, and rework. This multi-point assurance maintains the Flint AAAC Conductor Cable's uniform temper, tight stranding, mechanical balance, and standard compliance for optimal overhead installation.
Finished Product
Finished Flint AAAC Conductor Cable testing confirms ASTM B399 specs. Routine checks: diameter (31.0mm approx.), weight (2070 kg/km approx.), resistance (0.046 Ω/km). Mechanical: tensile (60 kN min), elongation. Process steps: sample cutting, grip mounting, load to failure, data recording, and fracture examination. Corrosion: 1000-hour salt spray. Additional: sag-tension at 75°C, weather cycling. Passing confirms the Flint AAAC Conductor Cable's low expansion, high ampacity, corrosion resistance, and suitability for overhead lines.
