The ZR-YJV22 (8.7/15kV) is a medium-voltage (MV) flame-retardant armored power cable designed for 15kV distribution systems, balancing dielectric integrity, mechanical strength, fire safety, and long-term reliability in industrial, utility, and critical infrastructure applications. Specifications:
ZR: Flame retardant (GB/T 18380, default Class C; Class A/B optional)
YJ: XLPE (cross-linked polyethylene) insulation
V: PVC outer sheath
22: Double steel tape armor + PVC inner sheath
This cable features a compact stranded copper conductor, three layers of extruded XLPE insulation (with a semi-conductive shield), a copper tape metal shield, steel tape armor (STA), and a flame-retardant PVC sheath. It can withstand continuous operation at 90°C, short circuits at 250°C (≤5 seconds), and harsh installation conditions, while maintaining a low level of partial discharge (PD) and meeting global medium-voltage cable standards.
Parameter
Value
Rated Voltage
8.7/15kV (Uo/U; 100% insulation level for solidly grounded systems)
Conductor
Class 2 compact stranded copper (Cu), 16–630mm²; 1/3 cores
Insulation
XLPE (cross linked polyethylene), thickness: 1.4mm (8.7kV); high dielectric strength, low loss, water tree resistant
Renewable Energy: Solar/Wind Farm Collection Systems (15kV On-Site)
Key Advantages (Focus of Global Buyers and Engineers)
Superior Electrical Performance: XLPE insulation material features low dielectric loss, high insulation resistance, and excellent partial discharge control (≤10pC at 1.73Uo), reducing the risk of long-term aging and failure. A copper strip shielding layer ensures 360° grounding continuity, reduces electromagnetic interference, and ensures safe return of fault current.
Enhanced Mechanical Protection: Steel tape armor (22) provides resistance to compression, impact, and rodents, suitable for direct burial, trench, or conduit installations—critical for civil and industrial sites. Compact copper conductors reduce cable diameter, facilitating installation in congested conduits.
Fire Safety and Compliance: ZR flame retardant rating (IEC 60332-3) limits flame spread, while the Low Smoke Option (LSZH) minimizes toxic fumes in confined spaces—critical for tunnels, metro systems, and high-rise buildings. Fully compliant with CE, RoHS, IEC, and GB standards, streamlining global project approval processes.
Long-Term Reliability and Cost Savings: Over 25 years of service life at rated conditions; a 90°C rated temperature allows for higher current carrying capacity than PVC-insulated cables, reducing required conductor size and material costs. Low maintenance costs and minimal unplanned downtime reduce total cost of ownership (TCO).
Engineering Flexibility: Available in single-core (high current) or three-core (compact distribution) configurations; customizable cross-sections (16–630 mm²) and flame retardant ratings (A/B/C) to meet project specifications. Suitable for directly grounded 15kV systems (100% insulation class).
Key Engineering and Procurement Considerations
Voltage Matching: 8.7/15kV is suitable for systems with a nominal voltage of 15kV (Uo=8.7kV); please confirm the system grounding method (direct grounding/impedance grounding) to select the appropriate insulation class.
Installation Rules: Both ends of the armor layer must be grounded; minimum bending radius ≥ 12 times the outer diameter; avoid installation below 0°C unless preheated.
Flame Retardancy and Fire Resistance: ZR = Flame Retardant (slows fire spread); for life safety circuits (fire pumps), please specify NH (fire resistant) cables.
Short-circuit rating: Verify that the conductor dimensions can withstand the fault current (≤5s) of 250°C as specified in IEC 60287.
Why Choose Our ZR-YJV22?
