Product Introduction
This 5-core tensile-resistant armored power cable (VV32 5×10) is rated at 0.6/1kV, specially developed for power transmission scenarios with longitudinal tension load. It adopts solid oxygen-free copper conductors, PVC core insulation, PVC inner bedding, continuous galvanized fine steel wire armor and anti-corrosion PVC outer sheath. Different from steel tape armored VV22 which only resists lateral extrusion, the fine steel wire armor of VV32 provides excellent tensile bearing capacity, suitable for mountain slope burial, river underwater crossing, overhead suspension and ditch-crossing laying. The integrated 5-core structure meets three-phase five-wire power distribution standards for civil and industrial outdoor power supply.
product key technologies
- Solid high-purity oxygen-free copper conductors (5 cores × 10mm², 3 phase + 1 neutral + 1 protective earth)
- Color-coded PVC insulation for each single core
- Elastic filling materials + binding wrapping tape
- PVC inner cushion bedding sheath
- Galvanized fine steel wire tensile armor layer
- Black wear-resistant anti-corrosion PVC outer protective sheath
-
- Solid Copper Conductors：High-density solid oxygen-free copper delivers stable low-resistance current transmission for three-phase power loads. The matched 5-core layout integrates live wire, neutral wire and ground wire into one cable, simplifying outdoor power distribution wiring without separate grounding cables. Rigid solid copper adapts long-distance fixed laying.
- PVC Core Insulation Layer：PVC insulation maintains reliable electrical isolation under 0.6/1kV rated voltage, with a long-term allowable operating temperature of 70℃, good moisture resistance and low raw material cost for conventional power distribution projects.
- Fillers & Wrapping Tape：Elastic fillers round out the cable body and buffer minor lateral extrusion during buried laying; wrapping tape fixes internal core groups to avoid dislocation deformation under tension load.
- PVC Inner Bedding Sheath：Isolates insulated core group and metal steel wire armor, prevents scratch damage to insulation and blocks electrochemical corrosion between copper conductor and galvanized steel wire.
- Fine Steel Wire Tensile Armor Layer：The core functional layer distinguishing VV32 from VV22: dense continuous fine steel wire bears longitudinal tensile force generated by mountain soil settlement, underwater buoyancy and overhead suspension, avoiding cable breakage; it also provides secondary protection against impact and rodent gnawing.
- Anti-Corrosion PVC Outer Sheath：Thickened PVC outer layer isolates internal armor from underground moisture, weak acid/alkali soil and river water, preventing galvanized steel wire rust and extending service life in wet outdoor & underwater environments.
Key Advantages
- Superior Tensile Resistance: Fine steel wire armor withstands large longitudinal tension, applicable for overhead, underwater and slope laying where VV22 steel tape armor cannot be used.
- Integrated 5-Core Three-Phase Five-Wire Design: Combines all power and grounding circuits in a single cable to tidy outdoor power layout and cut construction costs.
- Cost-Effective PVC Insulation System: Balances stable electrical performance and low production cost, the economical choice for non-heavy-load outdoor power distribution.
- Multi-Scenario Environmental Adaptability: Resists tension, minor extrusion, rodent bite, moisture and weak corrosion, compatible with cable trench, direct burial, overhead suspension and shallow water crossing.
- Customizable Safety Grades: Optional ZA/ZB/ZC flame retardant, NH fire-resistant, WDZ low-smoke zero-halogen modified versions for public building fire safety projects.
- National Standard Compliance: Fully manufactured in accordance with GB/T 12706 mandatory standard for low-voltage armored power cables.

FAQ
Q1: What does VV32 stand for?
A: The first V = PVC core insulation; the second V = PVC inner bedding sheath; 32 = galvanized fine steel wire tensile armor + PVC outer protective sheath.
Q2: What is the core difference between VV22 and VV32?
A: VV22 uses double steel tape armor, only resists lateral extrusion, limited to flat ground direct burial without tension; VV32 adopts fine steel wire armor, focuses on bearing longitudinal tension, suitable for overhead, underwater and slope laying with pulling force.
Q3: Can VV32 be directly laid in river water without extra conduit?
A: Standard VV32 supports shallow static water laying; customized thickened heavy anti-corrosion outer sheath is required for long-term flowing river or corrosive wastewater environments.
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: Do you supply flame retardant and low smoke zero halogen VV32 cables?
A: Full series modified products are available, including ZC-VV32 flame retardant, NH-VV32 fire-resistant, WDZN-VV32 low smoke zero halogen cables for subway, tunnel and high-rise fire safety projects.
Q6: What load scenarios is 0.6/1kV rated voltage suitable for?
A: For low-voltage AC three-phase power distribution below 1kV, cannot be used for 10kV medium-voltage power transmission.
