ZC-YJV22/flame retardant copper core cross-linked polyethylene insulated polyvinyl chloride sheathed steel belt armored power cable
ZC-YJV22/
ZC-YJV22 cable is a quality choice for power transmission. "ZC" indicates that it has C-class flame retardant properties. When a fire occurs, it can effectively suppress the spread of flame, greatly reduce the risk of fire, and ensure the safety of electricity use. Its conductor is made of high-purity copper material, with excellent conductivity, which can reduce the loss of power transmission and ensure stable and efficient power transmission. The crosslinked polyethylene insulating layer imparts excellent electrical insulation and good high temperature resistance to cables. The long-term working temperature of the conductor can reach 90℃, and when short-circuited (up to 5 seconds), the maximum temperature does not exceed 250℃. "22" represents steel belt armor and polyvinyl chloride outer sheath. Steel belt armor greatly enhances the mechanical strength of the cable, can withstand large external impacts and extrusions, and effectively protects the internal structure; the polyvinyl chloride outer sheath is wear-resistant, moisture-proof and corrosion-resistant, improving the environmental adaptability of the cable. This cable is suitable for power transmission and distribution systems of 0.6/1kV or below. It can be buried directly, penetrated into pipes or laid in cable trenches and tunnels. It is widely used in scenarios such as urban power grids, factory parks, and underground projects that require high mechanical strength and flame retardant performance of cables.

ZC-YJV22 Flame Retardant Copper Core XLPE Insulated PVC Sheathed Steel Tape Armored Power Cable: Robust Safety for Critical Power Networks
ZZC-YJV22 is a high-performance power cable engineered to deliver exceptional fire resistance, mechanical strength, and reliable power transmission in industrial, urban, and infrastructure projects. As a"flame retardant copper core cross-linked polyethylene (XLPE) insulated polyvinyl chloride (PVC) sheathed steel tape armored power cable,"it combines premium materials with advanced design to meet the toughest safety and performance standards.
Core Design and Dual Protection Features
- Copper Conductor: Stranded copper cores offer superior conductivity (≤0.0172 Ω·mm²/m) and low energy loss, ensuring efficient power delivery for high-load applications like factories, substations, and high-rise buildings.
- XLPE Insulation: Provides thermal stability (rated for 90°C continuous use) and moisture resistance, critical for long-term reliability in indoor and outdoor environments.
- Steel Tape Armor: The interlocking steel layer enhances mechanical protection against soil pressure, impact, and rodent damage, making it ideal for direct burial in roads, railways, or construction sites.
- Flame-Retardant PVC Sheath (ZZC Rating): Exceeds GB/T 18380 standards, offering self-extinguishing properties within 30 seconds and minimal smoke emission—critical for fire-prone areas like commercial complexes and industrial plants.
Applications in High-Stakes Environments
- Industrial Power Systems: Powers heavy machinery, transformers, and motor control centers in refineries and steel plants, where fire safety and mechanical durability are non-negotiable.
- Urban Grid Infrastructure: Used in underground cabling for cities, with steel tape armor resisting accidental damage from excavation or heavy traffic while meeting strict fire codes.
- Mining and Offshore Projects: Withstands harsh conditions like vibrations, moisture, and corrosion in mines and offshore platforms, ensuring uninterrupted power supply.
- Public Buildings: Installed in hospitals, data centers, and stadiums for critical power systems, where low smoke and halogen-free properties align with life-safety regulations.
Performance and Compliance
- Voltage Rating: Supports medium-voltage systems (0.6/1kV) and complies with IEC 60502 and GB/T 19666, ensuring global applicability.
- Mechanical Rigor: Steel tape armor withstands crush forces up to 3000N/m and bending radii of 15D, ensuring integrity during installation and operation.
- EMI Resistance: Optional shielding variants reduce electromagnetic interference, making it suitable for sensitive electronic environments.
Why ZZC-YJV22 is a Trusted Solution
- Enhanced Fire Safety: The ZZC rating provides an extra layer of flame retardancy, ideal for projects requiring the highest fire resistance levels.
- Cost-Effective Longevity: Copper’s conductivity and steel armor’s durability reduce maintenance costs over the cable’s 50+ year lifespan.
- Installation Flexibility: Despite its armor, the cable remains flexible for conduit routing, minimizing labor complexity in large-scale projects.
