Quality Control
Raw Material Test
Raw material testing for the Darien 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 Darien 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 Darien 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 Darien AAAC Conductor Cable's mechanical robustness, electrical reliability, durability, and suitability for direct burial low-voltage networks.

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.
