Flat/Round Flexible 1.5mm 2.5mm 4mm 6mm Electric MultiCore 3Core PVC Insulated Electrical Wires Rvv Cable and Wires
RVV stands for R-Flexible Cord, V-PVC Insulation, V-PVC Sheath. It is a multi-core, flexible, PVC insulated, and PVC sheathed cable. Think of it as a portable, all-in-one cable bundle with an outer protective jacket.
Key Specifications
1. Conductor:
- Material: Plain annealed copper.
- Type: Finely stranded (Class 5). This is the highest flexibility class, made of many thin copper wires, making the cable very soft and pliable.
2. Insulation & Sheath:
- Individual Core Insulation: PVC, color-coded (e.g., brown, blue, green/yellow).
- Outer Sheath: An additional layer of PVC that binds the insulated cores together, providing mechanical protection, shape, and integrity.
3. Voltage Rating:
4. Core Configuration:
- Available in 2, 3, 4, 5, 6+ cores.
- Common types: 2-core (Live & Neutral), 3-core (Live, Neutral, Earth), 4-core (3-phase + Neutral), 5-core (3-phase + Neutral + Earth).
5. Temperature Rating:
- Operating Temperature: Typically -15°C to +70°C.
6. Standards:
- Primary Standard: GB/T 5023.5 (China) / IEC 60227-5.
- Often known by the harmonized code H05VV-F or H07VV-F in European standards.
Advantages (Compared to Fixed Wiring Cables like BV/BVR)
- High Flexibility: The finely stranded conductors allow for repeated bending and movement without breaking. This is its primary advantage for movable applications.
- Integrated Protection: The outer PVC sheath provides good mechanical protection, minor abrasion resistance, and holds the cores together neatly. It does not require a separate conduit for basic protection.
- All-in-One Design: Multiple insulated cores are integrated into one cable, simplifying wiring for appliances and machinery.
- Ease of Installation: For exposed runs (e.g., along a wall in a clip), it's simpler to install than having to pull multiple separate BV wires through a conduit.
- Safety: Standardized color coding and a dedicated earth core (in 3+ core versions) ensure safe and correct connections.
Primary Applications
RVV is designed for internal wiring of equipment, appliances, and for lightweight, movable connections. It is not for fixed building wiring inside walls.
1. Appliance Power Cords & Extension Cords:
- The most common use. Used for small to medium household appliances, power tools, extension leads, and IT equipment. (Typically 300/500V, 2 or 3 core, 0.75mm² to 2.5mm²).
2. Internal Machine & Control Panel Wiring:
- For connecting internal components, sensors, and controls within machinery, CNC machines, conveyor systems, and control cabinets where flexibility is needed for door movement or service.
3. Signal Transmission & Control Wiring:
- Lower voltage (300/300V) RVV is widely used for security systems (CCTV cameras, access control), intercom systems, audio equipment, and automated control circuits.
4. Temporary Installations & Exposed Wiring:
- For temporary power on construction sites, event stages, or in workshops where cables are run along surfaces in cable clips or trunking.
5. Light Duty Power Distribution:
- Can be used for fixed, but accessible, light-duty power connections, such as for display lighting, signage, or internally within furniture.
Crucial Distinction: RVV vs. BV/BVR
Feature | RVV Cable | BV / BVR Cable |
|---|
Protection | Has its own outer sheath. | Requires external protection (conduit/trunking). |
Core Count | Multi-core (2, 3, 4, 5...). | Single-core only. |
Primary Use | Movable connections & internal equipment wiring. | Permanent, fixed installations inside walls. |
Installation | Clipped to surface, in open trunking, or free-moving. | Must be enclosed in conduit or buried in plaster. |
Analogy: Think of BV/BVR as the veins and arteries inside the walls of a building (fixed, protected). Think of RVV as the portable extension cord you plug into a wall socket or the wiring inside a washing machine (flexible, self-protected, movable).
Important Limitations & Safety Notes
- Not for Burial or Conduit: RVV is not designed to be buried directly in plaster, concrete, or soil. It lacks the robust armor required for such environments.
- Not for Outdoors: Standard RVV is not UV resistant or waterproof. It will degrade quickly in sunlight or wet conditions. For outdoors, use specific outdoor or armored cables (e.g., VVF).
- Current Capacity: Due to stranding, its current rating for a given size may be slightly different from a solid core cable. Always refer to ampacity tables.
- Not for High Mechanical Stress: While tough, it is not an 'armored' cable. It should not be placed where it is subject to crushing, heavy impact, or constant abrasion.
In summary, RVV is the go-to flexible, sheathed cable for connecting appliances, internal machine wiring, control systems, and for light-duty exposed power runs where movement or easy installation is required.
