BVR Multi-strand Copper Core Wire, Household and Home Decoration Project Wire, Insulated, National Standard Flexible Wire.

Unified Core Features

1. National Standard Compliance

   Strictly meets GB/T 5023.3-2008 standards, with mandatory CCC certification. Conductor cross-sectional area, insulation thickness, and resistance all meet national requirements, no shoddy “thin-core” or “short-length” issues.

2. High-purity Oxygen-free Copper Core

   Copper purity ≥99.99%, low resistance, low heat generation, stable conductivity. Anti-oxidation treatment on the conductor surface ensures a service life of over 20 years.

3. Durable PVC Insulation

   Insulation layer adopts high-density flame-retardant PVC (ZR/ZC grade optional), with properties of wear resistance, moisture resistance, acid and alkali resistance. Long-term working temperature: -15℃ to 70℃; high-temperature customized version can reach 90℃/105℃.

4. Super Flexibility for Construction

   Multi-strand thin copper wire twisting structure, easy to bend and not easy to break. It can pass through narrow pipe holes and complex corners, reducing construction difficulty and labor costs.

5. Standard Color Coding

   Conforms to national electrical installation specifications:

   • Red/Yellow/Green: Live wire
   • Blue: Neutral wire
   • Yellow-Green: Ground wire

     Clear color distinction avoids wiring errors.
