Quality Control
Raw Material Test
Raw material testing for the Elgin AAAC Conductor Cable ensures compliance with ASTM B398 and IEC 61089 standards. Aluminum alloy ingots (6201-T81) are inspected for chemical composition (Mg 0.6-0.9%, Si 0.5-0.9%, Fe <0.5%) using spectrometry. Wires undergo conductivity (>53% IACS), tensile strength (295-325 MPa), and elongation (>3.5%) checks with universal machines. Samples are subjected to heat treatment simulation at 180°C for aging verification and impurity analysis via microscopy. Corrosion resistance is tested in salt spray chambers for 1000 hours. The step-by-step process: incoming batch verification, random sampling, physical/mechanical testing (diameter tolerance ±0.03mm, weight per length), chemical confirmation, accelerated aging trials, and material release decision.
Process inspection
During the manufacturing of the Elgin AAAC Conductor Cable, process inspection adheres to ASTM B399. Alloy wire drawing ensures diameter tolerance (±0.03mm) and surface smoothness with micrometers. Heat treatment furnace controls temperature (180-200°C) and time for T81 temper via thermocouples. Stranding line monitors 61-wire lay ratio (12-16 times diameter), compactness, and tension balance using optical sensors. Real-time checks for ovality and strand continuity occur at multiple points. Final reeling verifies coil integrity. Key steps: pre-stranding material annealing confirmation, parameter logging (speed, tension), intermediate sampling for tensile testing, defect rejection (breaks/cracks), and post-stranding dimensional verification.
Finished Product
The finished Elgin AAAC Conductor Cable undergoes comprehensive testing to ASTM B399 standards. Routine tests include overall diameter (34.0mm approx.), weight per length (2480 kg/km approx.), and DC resistance (0.038 Ω/km at 20°C). Mechanical tests cover ultimate tensile strength (72 kN min) and elongation using universal machines. Electrical withstand and partial discharge checks confirm integrity. The process steps: reel sampling, preparation with grips, gradual load application to break point, timed hold for creep, post-test fracture analysis, and documentation. Additional verifications include corrosion resistance (1000-hour salt spray), lay length, and weather simulation (UV/ice loading).

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.
