Key Advantages of 3*400mm² Underground Power Cable
Superior Mechanical Protection
The dual-layer Steel Tape Armor (STA) provides 360° protection against high radial pressure and accidental mechanical impact, making it the "Gold Standard" for direct burial.
High Current Carrying Capacity
The 3*400mm² core utilizes class 2 stranded copper, minimizing power loss and ensuring stable transmission for heavy industrial loads.
Extreme Durability
XLPE insulation offers excellent thermal stability and chemical resistance, extending the cable's service life to over 25 years.
Pest & Rodent Resistance
The robust steel layer forms an impenetrable barrier against rodent attacks in underground tunnels.
Structural Anatomy of YJV22 3*400mm²
- Conductor: Annealed stranded copper (Class 2) for maximum conductivity.
- Conductor Screen: Semi-conductive material to uniform electrical stress.
- Insulation: High-quality XLPE for superior dielectric strength.
- Insulation Screen: Semi-conductive layer for electrical field optimization.
- Metallic Screen: Copper tape screen for grounding and fault current protection.
- Inner Sheath: PVC bedding layer to protect core insulation.
- Armor: Double Steel Tape (STA) for heavy-duty mechanical shielding.
- Outer Sheath: UV-resistant, flame-retardant PVC (ST2).
Application Scenarios
Optimized for high-voltage infrastructure and heavy industrial power networks.
