Quality Control
Raw Material Testing
Raw Material Test for the 2 AWG IRIS AAC Cable begins with incoming aluminum alloy 1350 rods. Laboratory analysis confirms chemical composition, with aluminum content exceeding 99.5% and controlled trace elements. Mechanical properties including tensile strength, elongation, and hardness are rigorously tested to ASTM B-230 specifications. Conductivity measurements ensure compliance with 61.2% IACS. Surface quality inspection using advanced imaging detects scratches, pits, or inclusions. Dimensional accuracy of rods is verified before drawing. Only batches meeting every criterion advance to wire drawing and stranding. This comprehensive raw material validation guarantees the foundation for a high-performance 2 AWG IRIS AAC Cable with exceptional electrical and mechanical characteristics suitable for long-term overhead use
Process Inspection
Process Inspection during 2 AWG IRIS AAC Cable production focuses on precision at each manufacturing phase. Wire drawing maintains exact diameter tolerance of 0.0974 inches with continuous monitoring. In the stranding machine, real-time tension control and revolution counters ensure uniform 7-strand helical configuration without gaps or overlaps. Lay length is measured frequently against design specifications. Intermediate sampling includes visual, dimensional, and partial electrical resistance checks. Environmental conditions in the plant are controlled to prevent contamination. Any process parameter deviation is documented and corrected immediately. These ongoing inspections safeguard the structural integrity and conductivity of the IRIS AAC conductor, delivering a consistent, defect-free product that excels in overhead transmission and distribution applications
Finished Product
Every completed reel of 2 AWG IRIS AAC Cable undergoes thorough Finished Product testing. Comprehensive dimensional checks confirm overall diameter, strand alignment, and lay consistency. Electrical tests measure DC resistance to ensure it stays within 0.260 ohms per 1000 ft at 20°C. Mechanical tests verify minimum breaking strength of 1,350 lbs and elongation properties. Full visual and tactile inspection identifies any surface irregularities. Additional samples may undergo accelerated aging or environmental simulation for validation. All results are recorded with batch traceability. Only products fully compliant with ASTM B-231 standards receive final approval and labeling. This final quality gate ensures the 2 AWG IRIS AAC Cable provides reliable, high-conductivity performance for demanding utility overhead line installations worldwide.

FAQ From Customers
-
What are the advantages of power cables and overhead lines?(1) Reliable operation, because it is installed in a hidden place such as underground, it is less damaged by external forces, has less chance of failure, and the power supply is safe, and it will not cause harm to people; (2) The maintenance workload is small and frequent inspections are not required; (3) No need to erect towers; (4) Help improve power factor.
-
Which aspects should be considered when choosing the cross section of a power cable?(1) The long-term allowable working current of the cable; (2) Thermal stability once short circuited; (3) The voltage drop on the line cannot exceed the allowable working range.
-
What are the measures for cable fire prevention?(1) Use flame-retardant cables; (2) Use fireproof cable tray; (3) Use fireproof paint; (4) Fire partition walls and fire baffles are installed at cable tunnels, mezzanine exits, etc.; (5) Overhead cables should avoid oil pipelines and explosion-proof doors, otherwise local pipes or heat insulation and fire prevention measures should be taken.
-
What should be paid attention to during the transportation and handling of cables?(1) During transportation, loading and unloading, cables and cable reels should not be damaged. It is strictly forbidden to push the cable reels directly from the vehicle. Generally, cables should not be transported and stored flat. (2) Before transporting or rolling the cable reel, ensure that the cable reel is firm, the cable is wound tightly, the oil pipe between the oil-filled cable and the pressure oil tank should be fixed without damage, the pressure oil tank should be firm, and the pressure indication should meet the requirements.
-
What inspections should be carried out for the acceptance of cable lines?(1) The cable specifications should meet the regulations, the arrangement should be neat, no damage, and the signs should be complete, correct and clear; (2) The fixed bending radius of the cable, the related distance and the wiring of the metal sheath of the single-core power cable should meet the requirements; (3) The cable terminal and the middle head should not leak oil, and the installation should be firm. The oil pressure of the oil-filled cable and the meter setting should meet the requirements; (4) Good grounding; (5) The color of the cable terminal is correct, and the metal parts such as the bracket are completely painted; (6) There should be no debris in the cable trench, tunnel, and bridge, and the cover should be complete.
