Copper Conductor Low Voltage Cable Offering Excellent Conductivity and Mechanical Strength for Electrical Installations

YJLV22 is a standard steel-tape armored aluminum core power cable conforming to GB/T12706 and the harmonized IEC60502 industry standards. It features a five-layer structure: compacted pure aluminum conductor, cross-linked polyethylene (XLPE) insulation, PVC inner lining, double-overlapping steel tape armor layer, and PVC outer sheath. Unlike copper core YJV22 and alloy core YJLHV22 armored cables, this product uses high-purity electrical-grade aluminum as the conductive medium, achieving a balance between raw material costs and basic power transmission performance. Furthermore, it incorporates a steel tape armor layer specifically designed for installation environments susceptible to external mechanical shock, soil compaction, and damage from underground rodents (e.g., direct burial, trench backfilling, and road crossings). This product has gained widespread acceptance among municipal power design institutes, infrastructure EPC contractors, plant electrification retrofit investors, and major global power importers. Our production facilities can customize the shell formula and fine-tune the armor thickness according to the official construction drawings provided by our clients, and use non-standard core material combinations. All finished products undergo continuous certification testing in our factory laboratory to meet international tender document review and cross-border customs clearance requirements.

• Significant Raw Material Cost Optimization: Unit procurement costs are approximately 40%–55% lower than those of copper-core YJV22 armored cables of the same cross-section, resulting in significant cost savings for large infrastructure projects with tight material budgets.
• Reduced Overall Weight: The total weight of the finished cable is approximately half that of a comparable copper-core armored cable, reducing land transportation costs and on-site hoisting and laying labor costs during concentrated construction phases.
• Mature Industry Standardization: Large-scale standardized production shortens delivery cycles for standard specifications, supporting emergency replenishment needs to address unforeseen project construction adjustments.

• Municipal Power Grid Upgrade and Renovation Projects: Underground trunk cable laying for converting overhead power lines to underground power grids in old urban areas; underground power layout for municipal road expansion and urban greenbelt power distribution networks crossing roads.
• Industrial Park Construction: Laying underground main incoming cables for the power distribution networks surrounding mineral processing plants, light industrial parks, and chemical production bases.
• Transportation Infrastructure: Underground power cabling along highway auxiliary facilities; outdoor fixed power pipelines around airports; and external power distribution projects for large railway stations.
• Large-Scale Civil Engineering: Underground pipeline power distribution for ultra-large logistics warehouse clusters and supporting power projects for suburban new town residential complexes.
• Special Geological Engineering: Power cabling for inland saline-alkali farmland transformation and rural power grid renovation projects in low-temperature frozen soil areas.

• Case 1: Southeast Asian Provincial Municipal Power Grid Upgrade Bidding Project
  An Indonesian municipal power contractor won a regional rural power grid upgrade project in 2025, ordering 427 kilometers of HDPE salt-resistant custom YJLV22 armored aluminum cable for roadside buried power conversion in tropical high-humidity soil environments. After more than a year of seasonal rainfall and soil erosion, no armor rusting or insulation damage occurred. The client also signed annual framework supply contracts with three surrounding counties for subsequent power upgrade plans.
• Case 2: Eastern European Light Industrial Park Phase II Expansion EPC Project
  A Slovakian industrial park general contractor selected our company's standard-grade YJLV22 cable to replace the aging buried cable in the existing factory power grid upgrade project. The lower procurement cost and easy installation characteristics effectively reduced the total material expenditure of the project and arranged supplementary bulk orders for the buried power engineering of the new workshop.
• Case 3: Procurement Cooperation for a New Agricultural Industrial Park in North Africa
  An Egyptian agricultural development company purchased 352 kilometers of YJLV22 4×120+1×70 armored aluminum cable for the construction of an underground power network for a large-scale modern farm in arid, high-temperature desert conditions. All products passed local power department inspection and were designated as the standard underground cable for subsequent agricultural development projects.

All aluminum ingots are sourced from formally certified large-scale smelters and come with complete component testing certificates. Each batch of aluminum ingots undergoes resistivity, tensile strength, and dimensional sampling inspections before stranding. XLPE and PVC raw materials are all qualified petrochemical-grade materials, free of any recycled waste plastics. Steel strips undergo professional rust-proof pickling treatment before armoring. All finished cables undergo high-voltage withstand voltage, partial discharge, and armor continuity sampling tests before delivery; any unqualified finished products are scrapped and not shipped.

The company's in-house R&D laboratory strictly follows customer construction drawings, adjusting sheath formulations, armor thickness, and non-standard cross-sectional parameters to develop customized YJLV22 products suitable for extreme geological conditions, resistant to low temperatures and chemical corrosion. Depending on the construction team's on-site cutting habits, various packaging options can be configured, including export-grade wooden barrel packaging and industrial coil packaging, to reduce residual cable waste and optimize the overall project procurement expenditure.

We provide a full set of ISO9001 quality management system certification, authoritative third-party GB testing reports, and IEC conformity certification documents, along with complete English versions. All certification documents can be directly used for overseas government bidding qualification verification and customs clearance in the destination country, efficiently simplifying bidding and import administrative procedures for cross-border purchasers.

• Cross-sectional area calculation principle: Calculate the total design load current and actual buried line length based on the distribution diagram, reserving a 13%~22% cross-sectional area margin to compensate for the inherent voltage drop of aluminum conductors. For buried trunk lines exceeding 250 meters, upgrade to a larger cross-sectional area specification.
• Environmentally Differentiated Selection Rules: Customized HDPE anti-corrosion outer sheath YJLV22 is used for projects buried in coastal saline-alkali land and chemical industrial parks; for municipal renovation projects in high-altitude permafrost areas, low-temperature modified sheath grade is selected.
• Accessory Matching Reminder: When procuring auxiliary materials, please use dedicated aluminum crimp terminals instead of ordinary copper terminals to avoid electrochemical corrosion at cabinet connection nodes.

Before backfilling, lay a fine sand layer under the cable to isolate sharp gravel from the outer sheath, preventing armor deformation and sheath puncture. When turning in the trench, the minimum bending radius specified in the standard should be followed to avoid damage to the inner structure. Buried lines should be kept away from underground high-temperature heat pipes to slow down the long-term aging of the sheath.

• Stable Delivery Arrangement: Three dedicated YJLV22 automated production lines and ample raw material inventory ensure that standard specifications of products are shipped within 10-17 working days after deposit confirmation, avoiding project stoppages due to material supply delays.
• Factory Direct Sales Prices, No Middleman Markups: Large EPC bidding bulk orders can enjoy tiered bulk discounts, helping procurement managers optimize the overall project budget and improve the overall economic benefits of the project.
• Full-cycle professional technical support: The company's experienced power cable engineering team provides free pre-sales load calculation and specification matching consultation, and offers remote technical troubleshooting guidance during customer on-site construction.
• Flexible long-term cooperation models: Small-batch sample trial orders can be provided for on-site performance verification before large-scale bidding and procurement; long-term global distributors and engineering contractors can sign annual fixed-price framework contracts to mitigate cost fluctuation risks caused by international non-ferrous metal price volatility.
