Quality Control
Raw Material Test
Raw material testing for the NA2XY-J/O Aluminium XLPE PVC 0.6/1kV Cable commences with aluminum rod inspection for alloy purity, conductivity, and surface defects per IEC standards. XLPE compound is evaluated for density, melt flow index, antioxidant content, and contamination via OIT and microscopy. PVC sheath material undergoes thermal stability, plasticizer level, and hardness testing. Fillers and bedding compounds are checked for compatibility. Samples face elongation, tensile strength, and accelerated aging. The step-by-step process: incoming batch verification, sampling per protocol, chemical analysis using spectrometry, mechanical property testing (before/after aging), electrical resistivity measurement, and approval/rejection decision. Only qualified materials advance.
Process inspection
During production of the NA2XY-J/O Aluminium XLPE PVC 0.6/1kV Cable, process inspection maintains strict quality control. Aluminum drawing/stranding is monitored for diameter tolerance and compactness with laser gauges. Insulation extrusion ensures uniform thickness and concentricity using online capacitance monitoring. Sheath application includes real-time spark testing and eccentricity checks. Core laying (for multi-core) verifies twisting and filler distribution. Marking permanence and surface quality are inspected. Key steps: material pre-drying confirmation, extrusion parameter stabilization (temperature, speed), intermediate wall thickness sampling, hot set testing for crosslinking degree, and immediate defect correction.
Finished Product
The finished NA2XY-J/O Aluminium XLPE PVC 0.6/1kV Cable is subjected to comprehensive testing. Routine tests include conductor resistance, AC voltage withstand (3.5kV), partial discharge (≤5pC), and insulation/sheath thickness verification. Flame retardancy (IEC 60332), cold impact, and bending tests confirm mechanical strength. Long-term moisture and heat aging assessments are conducted. The process steps: sample preparation, voltage ramp-up with monitoring, timed hold phase, environmental chamber cycling, post-exposure electrical/mechanical re-testing, and visual inspection. Additional checks cover shrinkage, ozone resistance, and core identification. Only cables passing all criteria are approved, validating the NA2XY-J/O Aluminium XLPE PVC 0.6/1kV Cable's safety, durability, and performance in low-voltage applications.

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.
