Jinhuanyu RVV 4.0-35mm² Copper-Core Flexible Wire

Jinhuanyu RVV Flexible Copper Cable — PVC Insulated & Sheathed, 99.99% Pure Copper (4–35mm²)

The Jinhuanyu RVV 4–35mm² series represents the gold standard in medium to heavy-duty flexible multi-core cabling solutions. Manufactured by Shenzhen Gold Universal Wire & Cable Co., Ltd. — a national high-tech enterprise with over 30 years of industry expertise — this cable is engineered for professionals who demand reliability, safety, and performance in demanding power distribution and control applications.

“RVV” stands for:

• R — Flexible (Soft) conductor

• V — PVC (Polyvinyl Chloride) insulation

• V — PVC (Polyvinyl Chloride) sheath

Every reel of Jinhuanyu RVV cable delivers 99.99% pure oxygen-free copper with minimum 99.99% purity, ensuring the lowest possible electrical resistance, maximum conductivity, and long-term reliability. The premium PVC insulation and sheath provide excellent flexibility, durability, and flame-retardant properties, making this cable the ideal choice for a wide range of electrical and electronic applications.

What Is RVV Cable?

RVV cable is a copper core PVC insulated and PVC sheathed flexible cable, also known as a soft sheathed wire. It is composed of multiple stranded copper conductors, each individually insulated with PVC, and then enclosed within an outer PVC sheath. The conductors are Class 5 stranded copper — multiple fine copper strands twisted together — which provides superior flexibility compared to solid-core cables.

The RVV designation follows the Chinese national standard nomenclature:

• R indicates a flexible/soft conductor construction

• V indicates PVC insulation on each conductor

• V indicates PVC outer sheath

RVV cables are designed for fixed or flexible installation in dry, damp, or wet environments where mechanical protection and electrical safety are required.

Core Advantages & Technical Excellence

1. 99.99% Pure Oxygen-Free Copper Conductor

At the heart of every Jinhuanyu RVV cable is a conductor crafted from high-purity oxygen-free copper with minimum 99.99% purity. The conductor employs a Class 5 stranded construction — multiple fine copper strands twisted together — which ensures minimal electrical resistance, superior conductivity, and reduced power loss. The copper’s exceptional purity guarantees the high performance that professionals demand, particularly in long-distance power transmission and high-current applications.

2. High-Quality PVC Insulation

Each conductor is insulated with high-grade PVC, offering excellent electrical insulation properties, abrasion resistance, wear resistance, and corrosion resistance. This robust insulation ensures long-term reliability and protects the conductor from environmental factors, extending the cable’s service life.

3. Durable PVC Outer Sheath

The outer PVC sheath provides an additional layer of protection against mechanical damage, moisture, chemicals, and environmental factors. The sheath is flame-retardant, self-extinguishing, and designed to withstand the rigours of industrial and commercial installations.

4. Class 5 Stranded Copper for Exceptional Flexibility

The Class 5 stranded construction — composed of multiple fine copper strands — endows the cable with outstanding flexibility. For 4mm² and above, the conductor stranding increases significantly to maintain flexibility while handling higher currents. This flexibility is invaluable for installations where the cable needs to be pulled through tight conduits, bent around corners, or routed in confined spaces.

5. Flame Retardant Performance

The PVC materials used in both insulation and sheath are flame-retardant and self-extinguishing, meeting IEC 60332.1 standards. This significantly reduces fire risk in the event of an overload or short circuit.

6. Wide Operating Temperature Range

The cable operates reliably across a wide temperature range from -30°C to +70°C, making it suitable for diverse environmental conditions.

7. Comprehensive Compliance & Quality Assurance

The cable is manufactured in strict accordance with GB 5023 and IEC 60227 standards. CCC certification is held for 2–5 core configurations, and the cable surface is clearly printed with meter marks, CCC certification details, and factory information, guaranteeing that you receive a product that is “full meter, full core” with authentic national standard quality.
