We categorize application scenarios based on laying methods, environmental conditions, and project types to help engineers and procurement personnel quickly complete model selection and solution matching:

This is the most typical application scenario for YJLV22. Suitable for direct burial in ordinary soil, roadside green belts, sidewalks, and backfill layers. The steel strip armor can withstand long-term soil pressure, gravel friction, and vibration caused by vehicle traffic. Widely used in urban and rural power grid upgrades, community underground power trunk lines, suburban distribution lines, and pipeline crossing projects. It also performs excellently in cable trenches and integrated pipe trenches in different regions.

Suitable for power distribution circuits in general manufacturing workshops, assembly plants, raw material warehouses, freight yards, and light industrial areas. The armored structure resists mechanical impacts, equipment vibrations, and on-site dust. The PVC outer sheath can withstand minor industrial contaminants, ensuring a continuous and stable power supply for production equipment, lighting, and monitoring systems.

Suitable for power distribution systems in residential communities, townhouses, ordinary office buildings, community facilities, and small commercial buildings. Meets basic electrical safety requirements for civil engineering projects. Stable performance, reasonable cost, and widely used in new residential communities and power renovation projects in existing communities.

Power lines supporting urban road reconstruction, street lighting, park facilities, water supply and drainage projects. The weather-resistant outer sheath withstands long-term outdoor exposure, rain, frost, and temperature variations. It is a universal cabling solution for various routine municipal auxiliary projects.

Supports cable trays, cable trays, and wall mounting in factories and buildings. Its moderate flexibility allows it to adapt to conventional conduit bends and compact layouts. Suitable for outdoor wall wiring and conventional equipment power supply lines in areas with low fire protection requirements.

Due to its low overall cost and readily available accessories, it is commonly used for temporary power supply on construction sites, on-site wiring, and auxiliary power distribution lines for large-scale projects.

The high-quality cross-linked polyethylene (XLPE) insulation layer possesses excellent dielectric properties and heat aging resistance, ensuring no insulation performance degradation even under long-term continuous operation and cyclic load fluctuations. The compacted aluminum conductor maintains stable conductivity, effectively reducing heat generation during power transmission and thus mitigating potential electrical risks.

Double-layer galvanized steel tape forms a robust protective barrier for the cable body, effectively buffering external impacts and resisting compression and tension during construction and daily operation. Even when buried in rocky soil or heavy-load areas, the internal core structure is fully protected, significantly reducing cable damage rates. The galvanizing process also prevents the steel tape from rusting in humid environments.

The modified polyvinyl chloride (PVC) outer sheath has good abrasion resistance and weather resistance, allowing it to operate normally in low-temperature, high-temperature, humid, and dusty environments. It has a certain tolerance to weak acids, weak alkalis and common substances in soil, and can adapt to most climate and geological conditions in conventional building areas.

Compared to copper-core armored cables, pure aluminum conductors significantly reduce raw material costs. The lightweight structure reduces transportation, hoisting, and manual laying costs. Compared to flame-retardant cables and low-smoke halogen-free (LSZH) series cables, its unit price is more competitive while meeting standard engineering requirements, bringing significant cost advantages to large-scale projects.

This cable has moderate flexibility, facilitating laying in cable trenches and trays. The pure aluminum conductor is compatible with mainstream aluminum terminals and connectors on the market. The construction technology is mature and widely mastered by numerous construction teams, effectively accelerating project progress.

The reasonable material combination and structural design ensure a design life of over 40 years under standard operating conditions. The product has a low long-term failure rate, requiring only routine visual inspections, thus saving on subsequent operation and maintenance manpower and material costs.

• Voltage Limitation: This product is specifically developed for 0.6/1kV low-voltage systems and must not be used in medium- or high-voltage power supply applications.
• Specification Selection: Calculate the conductor cross-sectional area appropriately based on the load current and transmission distance. For long-distance transmission, appropriately increase the cross-sectional area to control voltage drop.
• Environmental Screening: For projects located in coastal salt spray areas, highly corrosive areas, or locations with high fire resistance requirements, corrosion-resistant or flame-retardant upgraded cables should be selected.
• Load Derating: When buried in high-temperature soil or densely arranged cable trays, the actual load-bearing capacity should be appropriately reduced to avoid overheating.

• Construction Temperature: Laying work must not be carried out when the ambient temperature is below 0℃ to prevent brittle cracking of the PVC sheath and XLPE insulation layer.
• Bending Control: Strictly adhere to the specified minimum bending radius. Avoid sharp bends, twists, and excessive compression to prevent damage to the internal insulation layer.
• Tightening Control: Maintain uniform tension when laying cables. Excessive tension can cause conductor deformation and armor displacement.
• Underground Construction Standards: Lay a layer of fine sand around the cable and cover it with protective bricks or concrete slabs to isolate it from sharp objects.
• Terminal Treatment: Use dedicated matching aluminum terminals and standardize the crimping process to ensure a secure connection and avoid localized overheating.

• Document Verification: During the procurement process, check product qualification certificates, factory test reports, and inspection documents to ensure compliance with national standards.
• Visual Inspection: Inspect the cable surface for cracks, scratches, incomplete printing markings, etc., and verify that the model, voltage, and specifications are consistent.
• Sampling Inspection: For large orders, arrange random sampling and conduct insulation performance and withstand voltage tests according to project acceptance regulations.
• Storage Requirements: Store cables in a dry, ventilated, and cool warehouse using professional reels. Keep away from open flames, chemical reagents, and ground moisture. Prolonged open-air storage and direct sunlight are prohibited.
• Inventory Arrangement: Procure quantities according to the construction schedule to prevent long-term storage from affecting sheath performance.
