YJV22 Armored Power Cable - 8.7/15kV Copper Conductor
YJV22 is an XLPE insulated, PVC sheathed, steel tape armored power cable with copper conductors, engineered for robust power distribution in demanding environments requiring superior mechanical protection and reliability.
Cable Construction Breakdown
YJ: XLPE (Cross-Linked Polyethylene) Insulation
V: PVC Sheath
22: Double Steel Tape Armor
Applications
Underground Power Networks: Direct burial in industrial sites, renewable energy farms, and urban infrastructure
Industrial Plants: Wiring for motors, transformers, and machinery in high-stress or corrosive environments
Critical Infrastructure: Subways, tunnels, bridges, and power stations requiring mechanical protection
Outdoor Installations: Cable trenches and fixed routing with protection against environmental damage
High Performance: Copper conductor and XLPE insulation ensure efficient power transmission
Durability: Suitable for harsh environments, including direct burial and industrial settings
Versatility: Available in single-core/multicore designs with customizable conductor sizes (1.5-1000 mm²)

Frequently Asked Questions
What does YJV22 stand for?
YJ: XLPE (Cross-Linked Polyethylene) Insulation
V: PVC (Polyvinyl Chloride) Sheath
22: Double Steel Tape Armor (first '2' for steel tape, second '2' for PVC outer serving)
YJV22 is an armored power cable with copper conductors, designed for fixed installations requiring mechanical protection.
What is the main purpose of the steel tape armor?
The double steel tape armor provides superior mechanical protection against:
Crushing from heavy loads or backfill (essential for direct burial)
Impact and physical damage during or after installation
Rodent and termite attacks
It allows the cable to be installed in harsh environments without additional conduits.
What are the standard voltage ratings?
Low Voltage (LV): 0.6/1 kV (Most common for building and industrial power distribution)
Medium Voltage (MV): 6/10 kV, 8.7/15 kV, 12/20 kV (For primary power distribution in grids and large facilities)
Where should I use YJV22 cable?
It is ideal for installations where cables are exposed to mechanical stress, including:
Direct Burial in ground or cable trenches
Industrial Plants, mines, and manufacturing facilities
Infrastructure Projects like tunnels, bridges, and subways
Cable Trays or Ducts in areas with high risk of impact
What are the key installation guidelines?
Bending Radius: Minimum of 12 times the cable diameter (for multi-core) to avoid damaging armor and insulation
Grounding: Steel armor must be properly grounded at both ends for electrical safety
Pulling Tension: Use careful tension control to avoid armor distortion
Corrosion: Suitable for most soils, but additional protection may be needed in highly corrosive environments
What is the temperature rating?
Maximum Conductor Temperature (Continuous): 90°C (due to XLPE insulation)
Short-Circuit Withstand: 250°C (for maximum 5 seconds)
Installation Temperature: Should be ≥ 0°C to prevent PVC sheath from cracking
What is the packaging method for this type of cable?
Iron-Wood Cable Reel Packaging
Is YJV22 fire-resistant?
No. The standard YJV22 is not fire-resistant. Its primary function is mechanical protection. The PVC materials will burn and it will not maintain circuit integrity in a fire.
For fire safety, you need NH-YJV22 (Fire-Resistant) or WDZN-YJV22 (Fire-Resistant + Low Smoke Halogen Free).
