Jinhuanyu ZC-BVR 120-500mm² Copper-Core Flexible Wire

The Jinhuanyu ZC-BV 120-500mm² large-gauge solid copper building wire is a premium-grade electrical cable engineered for ultra-high-current applications where safety, reliability, and long-term performance are non-negotiable. Manufactured by Shenzhen Gold Universal Wire & Cable Co., Ltd. — a national high-tech enterprise with over 30 years of industry expertise — this wire is the trusted choice for main service entrances, industrial power distribution, heavy machinery, and large-scale commercial installations.

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

Sold by the meter, this wire 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 provides a critical safety barrier, making this wire the preferred choice for electrical contractors, industrial engineers, and infrastructure projects across North America, Europe, and beyond.

ZC-BV 120-500mm² Available in 120mm², 150mm², 185mm², 240mm², 300mm², 400mm², and 500mm² — these are the heavy-duty gauges required for main power feeds, large industrial motors, and commercial distribution systems.

Product Certifications:

• CCC (China Compulsory Certification) — Certificate No. 2003010105057030

• Guangdong Famous Brand Product

Technical Specifications

ZC-BV 120-500mm² Physical Specifications by Size:

Note: For sizes 120mm² and above, BV wire is supplied as solid single-strand conductor per GB/T 5023 standards. Ampacity ratings are calculated at ambient temperature 40°C with single-core cables arranged in open air. The above values are for single-core cables — derating factors apply for multi-core installations or bundled conduits.

Key Features & Benefits

1. 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 over long runs

• Cooler operation — better heat dissipation under heavy load

• No hydrogen embrittlement — excellent corrosion resistance and low-temperature performance

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

2. 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

• Meets GA 306-2007 industry standards — approved for use in public places

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

Key Safety Feature: Unlike ordinary PVC wires that contain no flame-retardant additives, Jinhuanyu ZC-BV incorporates high-performance flame retardants into the insulation layer, significantly slowing flame spread and providing critical escape time in emergency situations.

3. 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 length

• Reduced risk of electrical breakdown or current leakage

• Enhanced protection against shorts and fire hazards

4. CCC Certified — Quality Assured

Every Jinhuanyu ZC-BV wire carries the China Compulsory Certification (CCC) mark, certifying:

• Compliance with China's strictest safety standards

• Regular factory inspections and quality audits

• Traceable manufacturing and quality control

• Reliable performance you can trust

5. Environmentally Responsible Manufacturing

Jinhuanyu ZC-BV wires are manufactured with flame-retardant materials that:

• Reduce toxic gas emissions — minimizes release of hydrogen chloride (HCL) during combustion

• Lower smoke density — reduces smoke emission in case of fire

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

Applications

The Jinhuanyu ZC-BV wire in 120–500mm² sizes is purpose-built for ultra-heavy-duty fixed wiring applications:

Suitable Environments:

• Industrial plants and factories

• High-rise buildings and skyscrapers

• Commercial complexes and shopping centers

• Power distribution stations

• Infrastructure and civil engineering projects

• Mining and heavy industrial facilities

• Data centers and mission-critical facilities

Standards & Compliance

The Jinhuanyu ZC-BV wire is manufactured to the highest international and Chinese standards:

Flame-Retardant Classification:

• Class C (ZC) — Medium flame-retardant grade per GB/T 19666

• Meets the requirements for most residential and commercial buildings

• Verified flame spread performance per GB/T 18380 series standards

Installation Guidelines

General Requirements

• Rated Voltage (U₀/U): 450/750V

• Maximum Continuous Operating Temperature: 70°C

• Minimum Installation Temperature: 0°C (preheat cable if below this temperature)

Bending Radius Requirements (B Series)

For cable outer diameter (D) D ≥ 25 mm: Minimum bending radius ≥ 6 × D

Installation Tips

1. Inspect before installation — check for any 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 — use appropriately sized lugs and terminals

5. Account for voltage drop — for runs exceeding 30 meters, consider upsizing

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