RVVB Cable is a Flat Sheathed PVC Insulated and Sheathed Flexible Copper Cable, designed for low-voltage electrical connections requiring flexibility, compact routing, and ease of installation.
Cable Designation Breakdown
R: Flexible Stranded Copper Conductor
V: PVC Insulation
V: PVC Sheath
B: Flat Type Design
Applications
Household Appliances: Power cords for vacuum cleaners, refrigerators, and washing machines
Low-Voltage Systems: Wiring for lighting fixtures, doorbells, and security systems
Control Circuits: Connections for sensors, switches, and automation devices
Temporary Installations: Exhibition wiring and portable equipment
Key Advantages
Space-Saving Design: Flat structure allows for compact routing and easy surface mounting
Flexibility: Ideal for applications requiring frequent movement or bending
Cost-Effective: Affordable solution for low-voltage flexible connections
Ease of Installation: Lightweight and easy to handle
RVVB cable is suitable for low-voltage applications where flexibility and compact design are important. For enhanced fire safety, consider NH-RVVB (fire-resistant), or for outdoor use, RVVB with additional protection. Customizable conductor sizes (e.g., 2*0.5mm² to 2*2.5 mm²) are available.

Frequently Asked Questions
What does RVVB cable stand for?
R: Flexible stranded copper conductor
V: PVC (Polyvinyl Chloride) Insulation
V: PVC (Polyvinyl Chloride) Sheath
B: Flat parallel sheathed design
RVVB is a flat, parallel sheathed, PVC insulated flexible cable, designed for light-duty power and control connections requiring a space-saving profile and flexibility.
What is the main advantage of its flat "B" design?
The primary advantage is space efficiency. The flat, parallel structure allows for:
Easier surface mounting on walls, under carpets (if permitted by local code), or along baseboards
Simpler routing in narrow channels or confined spaces where a round cable might not fit
Aesthetic appeal for exposed wiring in furniture, displays, or appliances
What are its typical voltage ratings and applications?
RVVB is commonly used for light-duty, low-voltage applications:
Voltage Rating: 300/300V or 300/500V
Applications: Internal wiring of appliances (e.g., refrigerators, air conditioners), extension cords, low-voltage lighting, doorbells, intercom systems, and connections for small electronics or control devices
Is RVVB cable suitable for outdoor use or direct burial?
No. Standard RVVB cable is designed for dry, indoor use only. Its PVC sheath is not UV-resistant and is not suitable for prolonged exposure to sunlight, moisture, or direct burial. For outdoor applications, use a weather-resistant variant like RVVY.
Can RVVB be used for fixed in-wall wiring of a house?
No, it should not be used for permanent building wiring (e.g., behind walls, in ceilings for fixed outlets/lights). It lacks the necessary ratings (like higher temperature or fire safety classifications) required by most national electrical codes for fixed installations. For that, use cables like BV, BVVB, or NYM.
What are the key installation guidelines?
Bending: Bend along the flat plane to avoid sharp kinks that could damage internal conductors
Protection: In areas with potential mechanical damage, use cable protectors, conduits, or trunking
Securing: Use flat cable clips or adhesive-backed cable holders designed for flat wires
Temperature: Do not install near high-temperature heat sources
Does it have any fire safety features?
Standard RVVB has basic flame-retardant properties due to its PVC material but is not classified as a highly flame-retardant or low-smoke cable for critical applications. For enhanced safety in public buildings, specialized cables (e.g., ZR-RVVB or WDZ-RVVB) should be used.
What are common conductor configurations?
It is most commonly available in:
2-core: For simple connections (e.g., Live and Neutral)
3-core: For grounded connections (e.g., Live, Neutral, Earth)
Common conductor sizes range from 2x0.5 mm² to 2x2.5 mm².
Why choose RVVB over a standard round cable?
Choose RVVB when your project's primary needs are:
Space Constraints: Installing in a very thin or narrow space
Clean Aesthetics: For surface-mounted wiring where a flat profile looks neater
Specific Application: When the product design (like an appliance) requires a flat power cord
