Quality Control
Raw Material Test
Raw material testing for the Pigeon ACSR Conductor Cable ensures compliance with ASTM B230 and B232 standards. Aluminum wires (1350-H19) are inspected for purity (>99.5%), conductivity (>61.5% IACS), and elongation (>1.5%) using spectrometry and tensile machines. Steel core wires (Class A galvanized) undergo zinc coating mass (min 200g/m²), tensile strength (1300-1450 MPa), and ductility checks via wrap and torsion tests. Samples are subjected to corrosion simulation in salt spray chambers and impurity analysis via microscopy. The structured process: incoming batch verification, random sampling, physical/mechanical testing (diameter, weight per length), chemical composition confirmation, accelerated aging trials at 150°C, and material release decision.
Process inspection
Process inspection in Pigeon ACSR Conductor Cable manufacturing maintains precision per ASTM B232. Aluminum drawing ensures wire diameter tolerance (±0.025mm) and surface smoothness with micrometers. Steel core galvanizing controls zinc thickness (80-100µm) and adhesion via stripping tests. Stranding line monitors 6/1 lay ratio (aluminum around steel), compactness, and tension balance using optical sensors. Real-time checks for ovality and strand continuity occur at multiple points. Final lubrication and spooling verify coil integrity. Key steps: pre-stranding material dryness confirmation, parameter logging (speed, tension), intermediate sampling for microscopy, defect rejection (breaks/cracks), and post-stranding dimensional verification. This multi-point oversight ensures the Pigeon ACSR Conductor Cable achieves uniform stranding, optimal steel-aluminum bonding, and corrosion protection.
Finished Product
The finished Pigeon ACSR Conductor Cable undergoes comprehensive testing to ASTM B232 standards. Routine tests include overall diameter (12.75mm), weight per length (383 kg/km), and DC resistance (0.338 Ω/km at 20°C). Mechanical tests cover ultimate tensile strength (29.5 kN) and elongation using universal machines. Electrical withstand and partial discharge checks confirm insulation absence 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 zinc coating uniformity, lay length (300-400mm), 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.
