| Construction Description — ZC-YJV22 3×185+2×95 mm² armored LV power cable | |||
| Layer-by-layer armored power cable: Cu conductors / XLPE insulation / filler / double steel tape armor / PVC sheath · 0.6/1 kV · 90 °C · ≈ 62 mm | |||
| 1. Product Identity & Ratings | |||
| ZC-YJV22 3×185+2×95 is a 5-core (3P+N+PE) low-voltage steel tape armored XLPE power cable rated 0.6/1 kV, 90 °C continuous. Built per GB/T 12701 / IEC 60502-1, ZC flame retardant per GB/T 19666. Designed for distribution mains and direct burial. Finished OD ≈ 62 mm, mass ≈ 8200 kg/km, on wooden drums. | |||
| 2. Five Copper Conductors (3+2) | |||
| Three 185 mm² phase conductors (compact stranded Cu, ~60×2.05 mm) plus two 95 mm² conductors for neutral and protective earth (~19×2.53 mm). Phase resistance ≤ 0.0991 Ω/km; N/PE resistance ≤ 0.193 Ω/km at 20 °C. | |||
| 3. XLPE Insulation | |||
| Cross-linked polyethylene insulation, 1.8 mm on phase cores and 1.6 mm on N/PE cores. XLPE operates at 90 °C continuous (250 °C short-circuit), higher than PVC. This allows higher ampacity for the same cross-section. | |||
| 4. Steel Tape Armor (22) | |||
| Double steel tape armor gap-wrapped over the cored assembly. Provides mechanical protection for direct burial — resists crush and rodent damage. The armor must be grounded at both ends for safety. | |||
| 5. Site Handling & Operational Notes | |||
| • Bend radius 15×OD (≈ 930 mm). • Direct burial / trench / duct. • Site DC test 2.4 kV / 15 min before energizing. • Armor must be grounded. • At 8200 kg/km, heavy — use cable rollers. • Pre-heat below 0 °C. |
8. Standards & Conformity. GB/T 12701 (LV power cables); IEC 60502-1 (international); GB/T 3956 (conductors); GB/T 19666 (ZC flame retardant).
9. Packaging, Storage & Logistics. Wooden drums, 100 m per drum. Continuous marking: ZC-YJV22, 3×185+2×95, 0.6/1kV, GB/T 12701. Store indoors, dry.
10. Procurement Specification. State "ZC-YJV22 0.6/1 kV 3×185+2×95" + drum length. Confirm against factory test certificate.
11. Cable Industry FAQ.
- Q1: What does "3×185+2×95" mean? Three 185 mm² phase conductors (L1/L2/L3) plus two 95 mm² conductors — one neutral (N) and one protective earth (PE). This is a 5-core 3-phase 4-wire system.
- Q2: What is the difference between this and a 3-core YJV22? The 5-core (3+2) version includes neutral and earth conductors built in. A 3-core YJV22 requires separate N and PE runs. The 5-core is a complete distribution cable.
- Q3: What does "ZC" mean? ZC = flame retardant Class C per GB/T 19666. The cable self-extinguishes after the flame source is removed.
- Q4: Why is this a low-voltage cable? Rated 0.6/1 kV — used for building and industrial distribution. The previous YJV22 series was 8.7/10 kV (medium-voltage). This cable carries the final distributed power, not the primary transmission.
- Q5: Can this be directly buried? Yes — the double steel tape armor (22) provides crush and rodent protection for direct burial in trench.
- Q6: What is the ampacity? Approximately 370 A in free air at 25 °C. In buried conditions, derate based on soil thermal resistivity and grouping.
- Q7: Must the armor be grounded? Yes — the steel tape armor must be grounded at both ends for safety and electromagnetic shielding.
- Q8: What is the bending radius? 15×OD ≈ 930 mm — large cable requires generous bends. Use cable rollers during pulling.
- Q9: Can this be used outdoors? Yes — the PVC sheath is suitable for outdoor and direct burial. For UV-exposed aerial runs, use UV-stabilized sheath or conduit.
- Q10: What is the test voltage? Routine factory test 3.5 kV AC / 5 min. Site DC test 2.4 kV / 15 min before energizing.
- Q11: Why XLPE instead of PVC? XLPE operates at 90 °C (vs 70 °C for PVC), allowing higher ampacity for the same cross-section and better short-circuit withstand (250 °C vs 160 °C).
