Built for Demanding Power Delivery in Subsurface Networks
The YJV22 is a copper-core, XLPE-insulated electric cable reinforced with steel tape armor, purpose-built for fixed installations in harsh and confined environments. Operating under AC 0.6/1kV conditions, it supports buried, trench-laid, or ducted installations across infrastructure and industrial projects. Unlike surface-level power wiring, this cable is optimized for mechanical stress, external compression, and unpredictable underground shifts. Its armored profile prevents structural damage and conductor fatigue, making it suitable for primary or secondary power cable systems where safety, thermal resilience, and physical durability are non-negotiable.

Layered Composition Enables Longevity and System Integrity
At the core of the YJV22 is a high-purity copper conductor selected for superior electrical performance. Surrounding this, the XLPE insulation maintains dielectric strength across high thermal cycles while resisting chemical degradation. What sets this power cable apart is the galvanized steel tape armor—applied helically to absorb shock, minimize crush damage, and protect against rodents. The outer PVC sheath serves a dual role: it resists fire propagation while sealing out moisture and corrosive agents. Each layer is engineered for synergy, ensuring that the cable withstands mechanical stress without compromising transmission efficiency.

Ready for Harsh Installations and Long-Term Performance
Designed with real-world conditions in mind, this standard power cable can operate at 90°C under normal loads and endure 250°C during short circuits (up to 5s). Its bend radius accommodates practical routing in narrow cable trenches or congested electrical rooms. With performance standards aligned to GB/T12706 and IEC 60502-1, the YJV22 is compatible with national and global engineering codes. It’s a long-life solution for embedded energy delivery where once-installed cables must remain effective and secure over decades of service.

Product Advantages

Mechanical Defense via Galvanized Steel Tape Armoring
Unlike standard sheathed cables, the YJV22 is embedded with an armored layer composed of cold-rolled, galvanized steel tape. This provides a mechanical defense barrier against crushing force, ground shifting, and puncture hazards. Whether installed beneath roads, within cable tunnels, or between concrete slabs, the armor ensures uninterrupted function even in dynamic load zones. As a seasoned power cable manufacturer, Yuhong incorporates precise armoring tension and spiral geometry to balance rigidity and flexibility during deployment.

Insulation That Maintains Performance Under Thermal Load
The use of XLPE (cross-linked polyethylene) significantly enhances the cable’s ability to endure current-induced heating. In power-intensive applications—like motor drives, distribution panels, or backup power systems—this insulation prevents dielectric breakdown even under extended electrical load. Its low dielectric loss also improves efficiency by minimizing reactive current buildup. For electric wire systems running continuously or within tight thermal margins, this insulation choice directly contributes to safer and more energy-stable operation.

Protective Sheathing for Corrosive and Moist Environments
Cable installations often face variable humidity, airborne chemicals, or incidental liquid exposure. YJV22 counters this with an outer sheath made from flame-retardant PVC that is resistant to oil, acids, alkalis, and water ingress. It acts as a final defense barrier that preserves both internal structure and external signal clarity. In power cable supplier projects involving tunnels, basements, or chemically active environments, this sheathing reduces premature wear and contributes to lower lifetime maintenance costs.

Use Scenarios

Underground Loop Cabling for Metro Rail Systems
Electrical contractors building metro rail substations deploy the YJV22 as a critical underground loop for auxiliary power. Laid under station floors or inside reinforced cable channels, the armored electric cable resists transit-induced vibration, tunneling stress, and thermal build-up. Its anti-crush design ensures that accidental loading from service vehicles or adjacent construction does not damage the conductors—protecting rail signal systems, lighting, and emergency power feeds.

Energy Transmission for Cement Kiln Operations
In rotary kiln zones of cement plants, power engineers require armored conductors to feed crushing motors and exhaust fans. These power cables are routed through buried ducts or wall channels, often exposed to alkaline dust, heat, and corrosive fumes. Yuhong’s YJV22 performs well in this environment due to its armored stability and chemical-resistant sheath. Its ability to maintain current flow under prolonged vibration and temperature swing keeps production lines uninterrupted.

Buried Main Cable for Community-Level Power Projects
During rural grid upgrades or township electrification, civil electrical planners use YJV22 as the backbone buried conductor from transformers to endpoint service panels. Without the cost of added conduit, this standard power cable simplifies deployment and withstands uneven terrain or flood-prone conditions. Its armored and sheathed form resists soil moisture, trench settling, and surface compaction, providing long-term power assurance for residential or small commercial clusters.

FAQ

Does the steel tape interfere with grounding systems?
No, the steel armor is non-current-carrying and separated from live conductors, making it grounding-safe.

What sheath colors are available for YJV22?
Standard sheaths are black, but color customization is available for volume orders or circuit identification.

Can I use this cable in high-salinity areas?
Yes, the PVC outer layer resists salt corrosion, making it suitable for coastal or tunnel installations.

Is it available in flame-retardant and non-flame-retardant variants?
YJV22 is supplied with flame-retardant PVC as standard. LSZH versions can be discussed for special projects.

Do you provide installation support or guides?
Yuhong provides technical documentation, installation diagrams, and consultation for all armored power cable products.
