Quality Control

NA2X2Y Cables

Raw Material Test

Raw material testing for NA2X2Y Cables begins with aluminum rod inspection for electrical grade purity, elongation, and surface quality per IEC standards. XLPE insulation compound is analyzed for density, melt flow index, antioxidant content, and contamination using OIT and microscopy. PE sheath granules undergo weathering resistance, carbon black dispersion, and environmental stress cracking tests. Fillers and tapes are verified for compatibility. Samples are subjected to tensile strength, elongation, and accelerated aging simulations. The step-by-step process: incoming batch verification, sampling protocol, chemical composition analysis via spectrometry, mechanical property testing (before/after aging), UV/moisture pre-exposure checks, and material approval. Only qualified materials proceed, ensuring the NA2X2Y Cables' conductivity, insulation integrity, and exceptional outdoor durability foundation.

Process inspection

During the production of NA2X2Y Cables, process inspection maintains high-quality standards. Aluminum stranding is monitored for compactness and diameter tolerance using laser gauges. XLPE insulation extrusion ensures uniform thickness and concentricity with online capacitance monitoring. PE sheath extrusion includes real-time spark testing and eccentricity verification. Core assembly checks twisting and bedding distribution. Surface marking permanence and UV-resistant black color are inspected. Key steps: material pre-drying confirmation, extrusion parameter logging (temperature, pressure), intermediate hot set tests for crosslinking degree, defect detection/correction, and post-extrusion cooling control. This continuous monitoring guarantees the NA2X2Y Cables achieve void-free insulation, robust sheath adhesion, and full compliance with IEC 60502-1 throughout manufacturing.

Finished Product

The finished NA2X2Y Cables undergo comprehensive testing for performance validation. Routine tests include conductor resistance, AC voltage withstand (3.5kV), insulation resistance, and thickness measurement. Mechanical tests cover cold impact, bending, and abrasion resistance. Long-term tests assess UV aging, water absorption, and heat shrinkage. The process steps: sample preparation with terminations, voltage ramp-up and hold, environmental chamber cycling (UV/heat/moisture), post-exposure electrical/mechanical re-testing, and visual inspection. Additional verifications include flame retardancy and marking durability. Only cables passing all criteria are approved, confirming the NA2X2Y Cables' superior moisture protection, mechanical strength, and reliable operation in low-voltage underground and outdoor applications.

Application

NA2X2Y Cables are ideal for direct burial in utility networks, industrial parks, renewable energy projects, and infrastructure developments. Perfect for underground power distribution in wet soils, coastal areas, and locations requiring high resistance to environmental stress and mechanical damage.

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;
