Cable Type Comparison
BV: Rigid wire, a single-core copper wire
BVR: Flexible wire, a single-core wire made of multiple copper strands twisted together
RV: Also a flexible wire, generally not used for home decoration
BVVB: Rigid sheathed wire, two or more BV wires sheathed together
RVVB: Flexible sheathed wire, two, three, or four RV wires sheathed together
Frequently Asked Questions
1. What is a BV cable?
BV cable is a single-core copper conductor with PVC insulation, commonly used for power and lighting circuits in residential, commercial, and industrial buildings. It is known for its good electrical conductivity, safety, and cost-effectiveness, making it one of the most widely used building wires in the world.
2. What are the main features of BV cables?
Pure copper conductor for excellent conductivity and low resistance
Flame-retardant PVC insulation, safe and reliable
Good mechanical strength and flexibility
Moisture and chemical resistance
Stable performance and long service life
Easy installation for fixed wiring
3. What standards do BV cables comply with?
Our BV cables meet IEC 60227, GB/T 5023, and BS 6004 standards. We can provide CE, CCC, ISO, TUV, and RoHS certificates depending on market requirements.
4. What are the rated voltage and temperature range?
Rated voltage: 300/500V or 450/750V
Working temperature: up to 70°C for standard BV; higher grades (BV-90) can reach 90°C
Installation temperature: not lower than 0°C
5. What conductor sizes are available?
BV cables are available from 0.5mm² to 240mm² in single-core structure. Common sizes include 1.5mm², 2.5mm², 4mm², 6mm², and 10mm², which are widely used for lighting, power sockets, and equipment wiring.
6. What are the typical applications of BV cable?
BV cables are mainly used for indoor fixed installation, including: lighting and power distribution in homes, offices, and factories; electrical panels, switchboards, and control cabinets; wiring of household appliances and small machines; building and infrastructure electrical systems.
7. What is the difference between BV, BVR, and RV cables?
BV: Single-core, solid copper conductor (used for fixed wiring)
BVR: Single-core, stranded copper conductor (used for flexible wiring)
RV: Flexible stranded wire with finer copper strands (used for movable connections)
In summary: BV = solid, BVR = semi-flexible, RV = very flexible.
8. Can BV cables be used outdoors or underground?
Standard BV cable is designed for indoor fixed installation. For outdoor or underground use, we recommend BVV (PVC sheathed type) or YJV (XLPE insulated power cable), which provide additional protection against UV rays, moisture, and mechanical damage.
9. What information should I provide to get a quotation?
To offer an accurate price and lead time, please provide: cable model (e.g. BV); conductor size and number of cores; rated voltage; application environment (indoor, outdoor, conduit, etc.); quantity or length required; destination port and required certificates.
10. What is your production time and delivery method?
Normal lead time is 7-15 working days after deposit confirmation. We support FOB, CIF, and DDP shipping terms by sea, air, or courier. Samples can be provided for quality testing before bulk order production.
