Features
YJLV22 Cable is a heavy-duty armored power cable designed for primary underground electricity distribution networks. with lightweight 8000 series or EC-grade aluminum conductors, high-dielectric XLPE (Cross-linked Polyethylene) insulation, and a robust Double Steel Tape Armor (STA) layer under a durable PVC sheath.

|---|---|---|---|
| Full Name | XLPE Insulated PVC Sheathed Aluminum Power Cable | XLPE Insulated Steel Tape Armored PVC Sheathed Aluminum Cable | XLPE Insulated Steel Wire Armored PVC Sheathed Aluminum Cable |
| Conductor Material | High-purity EC-Grade Aluminum / 8000 Series Aluminum Alloy (Lightweight & Cost-effective) | ||
| Armoring Material | None (Unarmored) | STA (Double Steel Tape Armor) | SWA (Galvanized Steel Wire Armor) |
| Crush & Radial Resistance | Low (Requires extra conduit/pipe protection under soil pressure) | Excellent (Safely resists heavy backfill load and shifting soil crushing) | Moderate to High (Good resistance against lateral impacts and external rocks) |
| Tensile Strength (Pull Force) | Standard (Cannot handle vertical or long-distance pulling tension) | Low (Steel armor tapes may shift or unwrap under longitudinal force) | Superior (Withstands extreme vertical hanging tension and structural pulls) |
| Bending Radius & Flex | Smallest (Easiest to route in tight indoor trays and conduits) | Larger (Relatively stiff due to overlapping continuous metal armor) | Largest (Stiftest structure due to full perimeter galvanized steel wires) |
| Primary Installation | Indoor cable trays, concrete ducts, aerial brackets, solar PV inverter frames | Direct underground burial, utility soil trenches, public municipal grids | Vertical shafts, deep mining wells, high-drop utility towers, river crossings |
Heavy Mechanical Shield: Continuous overlapping double steel tape armor (STA) provides maximum radial crush resistance against sharp stones, compacted backfill soil, and underground mechanical hazards.
Elite Thermal Integrity: The cross-linked polyethylene (XLPE) core allows continuous normal loading at temperatures up to 90°C and temporary short-circuit survival up to 250°C.
Unmatched Cost Efficiency: Provides equivalent current capacity to copper wires at only a fraction of the raw material weight and procurement cost, helping projects cut material costs by up to 50%.
Soil & Chemical Immunity: The premium PVC outer sheath is formulated to resist moisture infiltration, underground acids, soil alkalis, and industrial oil tracking.
Application
Direct Underground Burial: The industry standard for main grid lines laid directly into soil trenches without the need for expensive structural conduit piping.
Solar PV Substation Links: Main AC transmission circuits routing between ground-mounted inverter arrays and central step-up transformers in massive solar plants.
Heavy Industrial Power Hubs: Primary distribution networks feeding power-hungry manufacturing centers, deep-level mining sites, and petrochemical yards.
Infrastructure & Civil Engineering: Main electrical feeders installed in commercial underground cable tunnels, utility ducts, and urban power transmission pathways.

FAQ
1. What are the engineering advantages of the conductor material used in your YJLV22 cable?
Core Metallurgical Advantage:
Our YJLV22 cable utilizes high-purity EC-Grade (Electrical Conductor) aluminum or premium AA8000 series aluminum alloy conductors. Compared to traditional copper cables, this drops the total cable weight by 40% to 50%, significantly reducing logistics costs and installation strain on cable trays. It offers a highly cost-effective, dependable power transmission solution for large-scale industrial projects and photovoltaic solar plants.
2. Why is the Double Steel Tape Armor (STA) critical for YJLV22 aluminum power cables?
Mechanical Shielding & Ground Burial:
The ’22’ in the YJLV22 designation signifies a robust Double Steel Tape Armored (STA) layer layered beneath the heavy-duty outer jacket. This interlocking double-wrap configuration provides superior resistance against radial compressive forces and high-impact mechanical crushing. It effectively shields the inner core against sharp rocks and ground shifting, making it perfect for direct-burial installations without requiring rigid conduits.
3. What voltage ranges does the YJLV22 cable family support for modern power grids?
Voltage Flexibility & Thermal Limits:
While extensively utilized for low-voltage main supply lines (0.6/1kV), our YJLV22 product range scales up to medium-voltage (MV) ratings including 8.7/15kV and 26/35kV grids by implementing thicker, super-clean Cross-linked Polyethylene (XLPE) insulation. The cable operates seamlessly at a continuous conductor temperature of 90°C and can withstand emergency short-circuit temperatures up to 250°C.
4. How does the YJLV22 armor cable perform in aggressive or damp soil environments?
Environmental & Chemical Endurance:
Engineered for harsh environments, the YJLV22 cable features a specialized, moisture-impermeable PVC outer sheath. This layer resists soil alkalinity, active organic acids, and industrial chemical runoffs. This critical protection ensures that the internal XLPE insulation remains free from destructive water treeing degradation, securing an extended operational lifespan exceeding 30 years in heavy industrial setups.
5. What are the B2B packaging options and manufacturing standards for wholesale YJLV22 cables?
Industrial Logistics & Wholesale Supply:
To prevent cross-sectional deformities and armor displacement during long-distance maritime transit, we package our YJLV22 STA cables exclusively on heavy-duty steel-wooden drums. As a direct factory supplier, we offer multi-core and 3+1 core configurations spanning 10mm² to 630mm² cross-sections. All shipments are backed by standard Routine Factory Test Reports to ensure absolute compliance at your destination port.
