0.6/1kV Low Voltage Alloy Cable with GB & IEC Certification for Real Estate,

YJHLV is a new type of optimized low-voltage power cable, using AA8000 series aluminum alloy solid conductors, cross-linked polyethylene (XLPE) insulation, and a PVC outer sheath. It is manufactured strictly according to GB/T 12706 and corresponding IEC international manufacturing standards. Unlike traditional pure aluminum YJLV and copper core YJV cables, its core design upgrades the conductor metallurgical composition, solving problems such as natural creep, poor bending toughness, and unstable connections inherent in traditional aluminum wires. This configuration is suitable for fixed underground trench laying, pipe wiring, wall embedding, and some overhead power distribution projects, and is widely used in municipal power upgrades, commercial real estate development, and factory expansion projects. Our factory can customize the core quantity, cross-sectional area, and sheath formula according to the different on-site construction environment requirements of global electrical design engineers, EPC contractors, and centralized procurement buyers. All finished products undergo comprehensive testing in our internal laboratory to meet international tender document review and cross-border customs clearance requirements.

• Rated Voltage Rating: Standard specification 0.6/1kV, medium voltage upgrades can be customized according to special power grid project requirements.
• Conductor Material: AA8000 heat-treated aluminum alloy conductor; optional special anti-corrosion alloy suitable for coastal high-salt-spray areas, cross-sectional area range 10mm²～400mm²
• Core Combination Options: 1-core, 2-core, 3-core, 3+1-core, 4-core, 4+1-core multi-specification configurations to match single-phase and three-phase power distribution circuit designs for buildings and municipal power grids.
• Conductivity Index: Optimized alloy formula ensures resistivity stably close to standard aluminum reference; XLPE layer insulation resistance exceeds 1000MΩ·km under normal environmental conditions, effectively reducing line voltage drop in long-distance power distribution cabling in large industrial areas.

• Creep Resistance: Metallurgical grain refinement significantly suppresses thermal creep of the conductor under long-term cyclic loading and temperature fluctuations, effectively avoiding the terminal contact problems and overheating issues commonly found in ordinary pure aluminum cables after years of operation.
• Excellent Bending Elongation: The bending performance of AA8000 alloy is 30% higher than that of ordinary electrical aluminum, facilitating the threading of wires through sharp corners during construction of pre-buried conduits and narrow trench bends.
• Tensile Strength and Compressive Strength: The integral compacted conductor structure combined with the rigid XLPE insulation layer can resist the extrusion deformation caused by backfill gravel during underground direct burial construction.

• Continuous Operating Temperature: The XLPE insulation layer allows for a long-term rated operating temperature up to 90℃ and a short-circuit instantaneous withstand temperature up to 250℃; the applicable ambient temperature range is -40℃ to +70℃.
• Inherent Standard Properties: Excellent moisture resistance, ozone resistance, and aging resistance. Customized high-density polyethylene (HDPE) outer sheath replacements or chemically resistant sheaths can be provided for power distribution projects in chemical industrial parks and landfills to prevent acid and alkaline soil erosion.

• Comprehensive Cost Optimization: Unit material cost falls between copper core YJV and ordinary pure aluminum YJLV, providing better long-term operational stability, thereby reducing maintenance costs for property management and power grid operating companies.
• Lightweight Features Reduce Construction Workload: The unit weight is approximately half that of copper cables of the same specifications, reducing labor costs for hoisting and duct laying during large-scale centralized construction.
• Stable Terminal Crimping Compatibility: The matching dedicated alloy terminal accessories avoid the risk of galvanic corrosion between dissimilar metals when connecting to the copper busbar of the distribution cabinet.

• Commercial and Residential Real Estate: Pre-buried main power lines in high-rise residential communities, underground power distribution in shopping malls, fixed cabling in underground parking garages, and auxiliary power engineering in communities.
• Municipal Power Grid Upgrade: Urban old community power grid renovation projects, rural overhead cable to underground cable conversion, roadside municipal power pipeline cabling.
• Industrial Park Construction: Main incoming cables for factory buildings, public power trench cabling in industrial zones, fixed power layout in warehouse and logistics parks.
• Infrastructure Engineering: Power distribution for new school construction, comprehensive electrical engineering for large hospitals, auxiliary power cabling for airports.
• Special Area Projects: Low-voltage power distribution in coastal industrial zones, customized modified sheathed anti-corrosion fixed cabling in chemical industrial parks.

Three Verified Global Project Collaboration Cases

All AA8000 alloy billets are sourced from certified upstream smelters and come with complete material testing reports. Each batch of incoming alloy undergoes sampling tests for resistivity, creep performance, and tensile strength before production. XLPE insulation granules use cross-linked raw materials from well-known brands, without any recycled plastics. All finished cables undergo partial discharge testing, high-voltage withstand voltage testing, and dimensional inspection before leaving the factory; unqualified products are completely isolated and scrapped, and will never enter the market.

Our in-house R&D laboratory can develop non-standard parameters according to clients' engineering construction drawings, including special salt spray resistant sheaths, low-temperature reinforced insulation, and customized non-standard cross-sections. Multiple packaging options are available: wooden export reels and plastic reel packaging customized according to the on-site cutting habits of the construction team, to minimize cable waste and optimize the total project procurement cost.

We offer complete ISO 9001 quality management system certification, authoritative GB product inspection reports, and IEC conformity assessment documents, all in English. All certification documents can be directly used for bidding on overseas government projects and customs import inspections in destination countries, greatly simplifying the bidding process and cross-border import administrative procedures for procurement parties.

• Cross-section Matching Principle: Calculate the total design load current and actual laying path length based on the distribution diagram, reserving a 12%~20% current margin to offset the line voltage drop caused by the transmission characteristics of alloy conductors; for long-distance trunk lines exceeding 200 meters, prioritize higher-specification conductors.
• Environmental Differentiation Selection: Select corrosion-resistant custom-sheathed YJHLV grade conductors for coastal cities and chemical industrial parks; select low-temperature modified grade conductors for municipal renovation projects in high-altitude areas.
• Terminal Matching Tips: During the matching of engineering materials, configure dedicated aluminum alloy terminals instead of traditional copper terminals to avoid electrochemical corrosion at connection nodes.

During direct underground backfilling construction, avoid scratching the outer sheath with sharp stones and metal edges; reserve an appropriate bending radius that meets national standards to prevent damage to the internal conductor structure. Keep cables away from boiler pipes and outdoor exposed radiant heat equipment and other long-term continuous high-temperature heat sources to extend their service life.

• Stable Production and Delivery Cycles: Four dedicated YJHLV automated extrusion production lines and stable raw material inventory ensure that standard specifications are shipped within 9-16 working days after deposit confirmation, avoiding project delays due to material supply disruptions.
• Direct Sales Cost Advantages: Eliminating intermediary markups; tiered bulk discounts are available for large EPC bidding orders, helping procurement personnel reduce overall project material budgets and improve overall project profit margins.
• One-Stop Professional Technical Support: The company's experienced team of power cable engineers provides free pre-order circuit matching consultation services, assists in optimizing specification selection based on project load parameters, and provides remote troubleshooting services during on-site construction.
• Flexible Long-Term Cooperation Models: Small-batch sample orders are accepted for on-site performance testing before bulk bidding; long-term global distributors and municipal engineering companies can sign annual fixed-price framework contracts to mitigate cost risks from fluctuations in international non-ferrous metal prices.
