YJLV Cable: Complete Guide to Aluminum XLPE Insulated Power Cable
YJLV cable is aluminum conductor XLPE insulated PVC sheathed power cable. Learn YJLV structure, specifications, advantages, applications, difference between YJV & YJLV, installation tips & selection guide for construction, industrial & distribution projects.
1. What Is YJLV Cable?
YJLV is the national standard model code for Aluminum Conductor Cross-Linked Polyethylene Insulated PVC Sheathed Power Cable. Break down model meaning clearly:
YJ: Cross-linked polyethylene (XLPE) insulation
L: Aluminum conductor (the most obvious distinction from copper YJV cable)
V: Polyvinyl chloride (PVC) outer sheath
YJLV belongs to low-voltage power cable, rated voltage commonly 0.6/1kV, widely used for fixed laying in indoor, outdoor, pipeline, trench and overhead power transmission occasions.
2. Internal Structure of YJLV Cable (From Inside to Outside)
Conductor: Hard aluminum stranded wire, compact stranding design, stable conductivity, light weight
Insulation Layer: XLPE cross-linked polyethylene, excellent insulation, heat resistance, anti-aging, high breakdown voltage
Filling & Wrapping Layer: Fill gaps between cores to keep round cable shape, prevent internal extrusion deformation
Outer Sheath: PVC protective jacket, moisture-proof, corrosion resistant, mechanical wear resistance
3. Main Technical & Basic Product Attributes
Rated voltage: 0.6/1kV (most conventional); medium voltage customized available
Core configuration: Single core, 2 core, 3 core, 3+1 core, 3+2 core, 4 core, 5 core
Common cross-section: 10mm², 16mm², 25mm², 35mm², 50mm², 70mm², 95mm², 120mm², 150mm², 185mm², 240mm², 300mm²
Long-term allowable working temperature: 90℃
Minimum bending radius: ≥10–15 times cable outer diameter
Flame retardant / fire resistant customized types optional upon demand
4. Core Advantages of YJLV Aluminum Cable
4.1 Cost Advantage
Aluminum raw material price is far lower than copper, greatly cutting overall project procurement cost for large-scale power distribution engineering.
4.2 Light Weight & Easy Construction
Aluminum density is only one-third of copper, lighter cable weight reduces transportation cost, laying labor intensity and support bracket load, ideal for long-distance overhead trunk lines.
4.3 Anti-Corrosion Performance
Aluminum has natural oxidation protection film, better adaptability to humid, slightly corrosive soil and outdoor atmospheric environment.
4.4 Sufficient Current-Carrying Capacity for Conventional Distribution
Suitable for medium and long distance power supply where high instantaneous overload is not required, fully meeting daily industrial and civil power transmission demands.
5. Typical Application Scenarios of YJLV Cable
Urban & Rural Low-Voltage Power Grid Renovation: Outdoor overhead lines, pipeline incoming and outgoing cables for community power distribution cabinets
Real Estate & Residential Projects: Building main power trunk, underground trench laying for residential district public power supply
Industrial Park & Factory Distribution: Workshop main incoming cable, power supply for factory auxiliary equipment
Road, Bridge & Municipal Engineering: Street lighting power lines, municipal pipeline power wiring
Agricultural Water Pump, Orchard & Remote Field Power Supply: Long-distance outdoor low-cost power transmission
6. Key Difference: YJLV vs YJV Cable (Most Frequently Searched Question)
| Item | YJLV Cable | YJV Cable |
|---|---|---|
| Conductor Material | Aluminum | Copper |
| Unit Price | Lower cost | Higher cost |
| Weight | Lighter | Heavier |
| Conductivity | Weaker, larger section needed for equal current | Higher conductivity, smaller cross-section option |
| Anti-Oxidation | Better | Ordinary |
| Suitable Scene | Long distance, budget-sensitive projects | Short distance, high load, high stability requirement |
7. Frequently Asked Questions (SEO Long-Tail Keywords Embedded)
Q1: Is YJLV cable aluminum or copper?
A: YJLV is aluminum conductor power cable; the letter L in model stands for aluminum, while YJV is copper conductor cable.
Q2: Can YJLV cable be buried directly underground?
A: Ordinary YJLV can be laid in pipe ducts. For direct burial without conduit, armored YJLV22 is suggested against extrusion and soil corrosion.
Q3: What is the maximum working temperature of YJLV?
A: Long-term permitted operating temperature of XLPE insulation is 90℃; short circuit allowable temperature can reach 250℃ within specified time.
Q4: Is YJLV cheaper than YJV cable?
A: Yes. Aluminum raw material cost is much lower than copper, so YJLV is more economical for large-length power distribution projects.
Q5: Can YJLV replace YJV directly?
A: Not directly interchangeable. Due to poorer conductivity, YJLV needs increased cross-sectional area to match current carrying capacity of equivalent YJV cable, and copper-aluminum transition joints are required for connection.
