Jinhuanyu BV 0.75-1mm² Copper-Core Single-Core Rigid Wire

The Jinhuanyu ZC-BV is a premium-grade solid copper building wire engineered for safety, reliability, and long-term performance in low-current applications. Manufactured by Shenzhen Jinhuanyu Wire & Cable — a company with over three decades of industry leadership — this wire sets the benchmark for quality in residential and commercial fixed wiring.

The "ZC-BV" designation tells you exactly what you're getting:

Every 100-meter reel delivers 100% pure oxygen-free copper with minimum 99.9% purity, ensuring the lowest possible resistance, maximum conductivity, and decades of reliable service. The flame-retardant PVC insulation adds a critical safety layer, making this wire the trusted choice for electricians, contractors, and homeowners across North America, Europe, and beyond.

Key Features & Benefits

100% Pure Oxygen-Free Copper Conductor

• 99.9% pure copper — no copper-clad aluminum (CCA), no alloys, no shortcuts

• Superior conductivity — lower electrical resistance means less energy loss

• Cooler operation — better heat dissipation under load

• Corrosion-resistant — no hydrogen embrittlement, excellent oxidation resistance

• Extended service life — 25–30 years under normal operating conditions

Class C Flame-Retardant PVC Insulation

• Self-extinguishing — flame stops when the ignition source is removed

• Flame spread prevention — slows fire propagation, providing critical escape time

• GB/T 19666 Class C certified — verified flame-retardant performance

• Low smoke emission — minimizes toxic smoke during combustion

• Thermally stable — maintains integrity even under high-load conditions

Consistent Insulation — Low Eccentricity

Jinhuanyu's precision extrusion process ensures the copper conductor is perfectly centered within the insulation. This means:

• Uniform wall thickness throughout the entire 100-meter length

• Reduced risk of electrical breakdown or current leakage

• Enhanced protection against shorts and fire hazards

Durable Yet Flexible

• High mechanical strength — resists abrasion, impact, and pulling stress

• Flexible for easy installation — bends cleanly without cracking, even in cold conditions

• Chemical-resistant — withstands acids, alkalis, and corrosive environments

• Weather-resistant — stable performance across varying temperature ranges

RoHS Compliant — Environmentally Responsible

Manufactured in full compliance with the EU RoHS Directive (2011/65/EU):

• No heavy metals — free from lead, mercury, cadmium, and hexavalent chromium

• Safe for indoor use — no harmful emissions during normal operation

• Safe for installers — reduces exposure to hazardous materials during handling

CCC Certified — Quality Assured

Every spool carries the China Compulsory Certification (CCC) mark, certifying:

• Compliance with China's most stringent safety standards

• Regular factory inspections and third-party quality audits

• Full traceability from raw material to finished product

Pro Installation Tips:

1. Inspect before installation — verify there is no visible damage to the insulation

2. Use proper stripping tools — avoid nicking or scoring the copper conductor

3. Follow local electrical codes — adhere to NEC, BS 7671, or other applicable standards

4. Ensure secure connections — tight, corrosion-free terminations prevent overheating

5. Test after installation — verify continuity and insulation resistance before energizing
