Key Advantages
1. Significant Overall Cost Savings
Uses AA8000 series aluminum alloy conductors, offering lower material cost than copper cable. Under comparable electrical performance, this reduces total project investment — ideal for residential communities, industrial parks, and long-distance outdoor distribution.
2. Lightweight, Easier Installation
Aluminum alloy has a much lower density than copper, making the cable roughly 40-50% lighter overall. This simplifies handling, tray-laying, and overhead installation, reducing crane/hoisting and labor costs.
3. Strong Anti-Creep Performance, Stable Connections
Compared to standard pure aluminum cable, the improved aluminum alloy resists creep deformation under long-term current load, reducing the risk of loose connections, overheating, and arcing at joints — improving long-term operational safety.
4. Good Flexibility and Corrosion Resistance
The aluminum alloy conductor is more flexible than standard aluminum, resisting fatigue cracking during bending. It also offers strong resistance to oxidation and electrochemical corrosion, suiting damp outdoor environments and cable trenches.
5. Reliable Electrical Performance, Versatile Installation
Insulated with silane cross-linked polyethylene (Si-XLPE), rated for continuous operation at 90°C conductor temperature. Suitable for cable tray and conduit installation; the armored version (YJLHV22) can be direct-buried for added mechanical protection. Widely used in real estate developments, industrial plants, and municipal outdoor lines.

Applications
- YJLHV (unarmored): Indoor cable tray/conduit installation; not suitable for direct burial. Ideal for long-distance distribution projects in residential and industrial parks where cost savings over copper are prioritized.
- YJLHV22 (steel tape armored): Suitable for direct burial, resistant to external mechanical stress. Used in tunnels and cable trenches (not recommended for high-tension pulling conditions). Widely applied in real estate developments and outdoor park distribution.
