YJLV22 is an economical armored aluminum power cable designed according to GB/T12706 and the harmonized IEC 60502 international standards. It consists of high-purity aluminum stranded conductors, cross-linked polyethylene insulation, a PVC inner lining, overlapping double-layer steel tape armor, and a weather-resistant PVC outer sheath. Unlike copper-based YJV22 and AA8000 alloy YJLHV22 armored cables, YJLV22 uses conventional high-purity electrical aluminum, significantly reducing raw material input while maintaining standard transmission capacity. Its built-in steel tape armor can withstand harsh environments such as direct burial in open trenches, heavy-duty ground laying in ports, and buried cabling near mines susceptible to heavy vehicle traffic, sharp rock penetration, and rodent damage. This cable is widely used by rural power investment companies, port construction EPC companies, mining enterprises, and cross-border power wholesalers. Our production base can provide customized termite-proof sheaths, low-temperature modified formulas, and non-standard core layouts based on customer engineering design drawings. All finished products undergo full-category laboratory testing at the factory to meet the requirements for overseas tender document review and customs import clearance.

- Conductor Configuration: Multi-layer compacted industrial pure aluminum conductor; optional aluminum conductor with anti-oxidation treatment, suitable for construction sites in coastal high-salt spray and chemically polluted soils, cross-sectional area range is 25mm²～630mm².
- Core Wire Arrangement Options: Single core, three core, 3+1 core, four core, 4+1 core, and other combinations, suitable for three-phase four-wire main incoming lines and branch lines of rural power grids and industrial park power distribution.
- Insulation Electrical Performance: XLPE insulation maintains an insulation resistance of over 950MΩ·km under normal environmental conditions; controllable conductor resistivity stabilizes power transmission and suppresses excessive voltage drop in long-distance buried trunk lines (over 350 meters) in vast rural distributed power grids.
2.2 Mechanical and Armor-Specific Performance
- Closed Double-Layer Steel Strip Protection: Continuous overlapping winding forms a robust mechanical barrier, resisting heavy backfilling pressure, forklift/construction vehicle crushing, and underground pest intrusion environments such as open-pit mines and ports. Compared to unarmored YJLV cables, this significantly reduces on-site maintenance workload.
- Compacted Aluminum Conductor Structure: Multi-layer compaction process improves the overall conductor density, effectively mitigating strand loosening and separation caused by long-term ground settlement of buried pipelines.
- Internal Buffer Pad Design: Isolates the rigid steel armor and XLPE insulation layer, preventing insulation scratches caused by slight armor displacement due to lateral soil compression and seasonal ground deformation.
2.3 Environmental Adaptability Parameters
- Long-Term Continuous Allowable Operating Temperature: Rated continuous operating temperature is 90℃, and the instantaneous short-circuit withstand peak temperature can reach 250℃. Applicable ambient temperature range: -42℃～+75℃
- Basic environmental resistance: Excellent waterproofness, ozone aging resistance, and resistance to general soil corrosion; the high-density polyethylene (HDPE) outer sheath can replace standard polyvinyl chloride (PVC) for buried engineering projects in acid- and alkali-contaminated mining areas and coastal saline-alkali land; termite-proof sheaths can be customized for rural power construction in tropical jungles.
Unique Competitive Advantages Compared to Other Armored Cables
- Superior Cost Control: Compared to YJV22 copper armored cables of the same cross-section, YJLV22 cables have approximately 42%~58% lower raw material costs, perfectly suited for large-scale rural power grid upgrades and low-budget infrastructure procurement plans.
- Lightweight Transportation Advantages: The total weight of the finished cable is less than half that of a copper armored cable of the same specifications, reducing container transportation costs and on-site hoisting labor costs during concentrated batch construction.
- Mature Standardized Production: Stable batch production of standard specifications shortens the production cycle and supports emergency replenishment to cope with sudden adjustments to project schedules.

5. Professional Selection Guidance for Electrical Engineers and Purchasing Managers and On-site Laying Specifications
5.1 Pre-Purchase Specification Selection Guide
- Cross-sectional area calculation rules: Calculate the total design load current and actual burial length based on the distribution diagram, reserving a 14%~24% cross-sectional area margin to compensate for the inherent voltage drop of aluminum conductors. For buried main lines exceeding 300 meters, select upgraded conductors with a larger cross-sectional area.
- Environmentally Differentiated Selection: Customized HDPE anti-corrosion sheaths (YJLV22) are selected for buried construction in coastal saline-alkali land and acidic mining areas; low-temperature reinforced sheaths are selected for rural power grid renovation in frigid mountainous areas; and termite-resistant modified sheaths are selected for projects in tropical jungle villages.
- Accessory Matching Recommendations: When purchasing auxiliary materials, use dedicated aluminum crimp terminals instead of traditional copper terminals to avoid electrochemical corrosion at distribution cabinet connections.
5.2 On-site Direct Burial Construction Standards
Before backfilling, lay a fine sand pad at the bottom of the cable to prevent sharp stones from scratching the outer sheath and causing deformation of the internal steel armor; when laying cables at trench corners, the specified minimum bending radius should be observed to avoid damage to the internal structure; buried lines should be kept away from underground heating pipelines to slow down the long-term aging of the sheath.
