Product Introduction
This five-core armored PVC power cable (VV22 3×25+2×16) is rated at 0.6/1kV, designed for three-phase five-wire low-voltage power distribution with mechanical damage risks. It adopts solid oxygen-free copper conductors, PVC core insulation, PVC inner bedding, double galvanized steel tape armor and anti-corrosion PVC outer sheath. The integrated armor structure provides impact, compression and rodent bite resistance, supporting direct underground burial without heavy steel conduits. With 3 large-section phase cores + 2 neutral/earth cores integrated in one cable, it simplifies power wiring for residential, industrial and municipal buried power supply projects.
product key technologies
1.Solid high-purity oxygen-free copper conductors: 3×25mm² phase cores + 2×16mm² neutral & protective earth cores.
2.Color-coded PVC insulation for each single core.
3.Elastic filling materials & binding wrapping tape.
4.PVC inner cushion bedding sheath.
5.Double-layer galvanized steel tape armor layer.
6.Black wear-resistant anti-corrosion PVC outer protective sheath.
- Solid Copper Conductors:High-density solid oxygen-free copper delivers low resistance and large ampacity for three-phase power load. The matched cross-section design (25mm² live wire + 16mm² N/PE wire) meets standard three-phase five-wire distribution requirements, integrating power transmission and equipment grounding in one cable.
- PVC Core Insulation Layer:PVC insulation provides stable electrical isolation between cores under rated 0.6/1kV voltage, with good moisture resistance and low raw material cost; long-term allowable operating temperature reaches 70℃.
- Fillers & Wrapping Tape:Elastic fillers round the cable structure and buffer extrusion during buried laying; wrapping tape fixes internal cores to avoid dislocation and friction damage.
- PVC Inner Bedding Sheath:Separates insulated core group and metal armor layer, preventing scratch damage to insulation and electrochemical corrosion between copper and steel tape.
- Double Galvanized Steel Tape Armor Layer:Core mechanical protection structure, effectively resisting underground rock extrusion, construction impact, rat and termite gnawing, complying with national direct-buried laying standards.
- PVC Outer Sheath:Thickened anti-corrosion PVC outer layer isolates internal armor from soil moisture, weak acid/alkali and dust, avoiding steel tape rust and extending service life in underground environments.
Key Advantages
- Direct Underground Burial Capable: Double steel tape armor removes the need for heavy steel conduits, cutting pipeline construction labor and material costs greatly.
- Integrated 5-Core Three-Phase Five-Wire Layout: Combines live, neutral and earth wires into a single cable for neat, simplified distribution wiring.
- Cost-Effective PVC Insulation Solution: Balances stable electrical performance and low production cost, the mainstream economical choice for conventional power distribution.
- Multi-Dimensional Environmental Protection: Resists extrusion, impact, rodent bite, moisture and weak soil corrosion, adaptable to cable trench, underground direct burial and indoor fixed laying.
- Wide Customization Options: Optional ZA/ZB/ZC flame retardant, NH fire-resistant and WDZ low-smoke zero-halogen modified versions for high fire safety demand projects.
- Standardized Production: Fully manufactured in accordance with GB/T 12706 national standard for low-voltage power cables.

FAQ
Q1: What does VV22 stand for?
A: The first V = PVC core insulation; the second V = PVC inner bedding sheath; 22 = double galvanized steel tape armor + PVC outer protective sheath.
Q2: What is the difference between VV and VV22 cables?
A: Ordinary VV cable has no steel tape armor, only suitable for indoor cable tray laying without mechanical impact risk; VV22 adds double steel tape armor, supporting underground direct burial with strong anti-extrusion and anti-rat performance.
Q3: Can VV22 be buried directly in soil without conduits?
A: Yes, standard double steel tape armor meets national direct-buried construction specifications; customized heavy anti-corrosion outer sheath is required for strong acid/alkali industrial soil.
Q4: What is the long-term allowable working temperature of PVC insulation?
A: Long-term continuous operating temperature is 70℃; short-circuit withstand temperature is 160℃ within 5 seconds.
Q5: What is the difference between VV22 and YJV22?
A: VV22 uses PVC insulation with lower heat resistance and lower cost; YJV22 adopts XLPE insulation with 90℃ long-term temperature resistance and larger ampacity for heavy-load power transmission.
Q6: Do you supply flame retardant and fire-resistant VV22 cables?
A: Full series modified products are available, including ZC-VV22 flame retardant, NH-VV22 fire-resistant, WDZN-VV22 low smoke zero halogen cables for subway, hospital and high-rise fire safety projects.
