BV35mm Single Core Copper PVC Electrical Building Wire
BV Cable is a PVC Insulated Single-Core Hard Copper Wire designed for fixed electrical installations in buildings, power distribution, and lighting systems. The name BV indicates:
B: Insulated Wiring (Chinese standard designation)
V: PVC (Polyvinyl Chloride) Insulation
Applications
Building Wiring: Fixed electrical circuits in residential, commercial, and industrial buildings
Power Distribution: Main power supply lines, lighting circuits, and socket wiring
Control Systems: Simple control wiring for switches and outlets
Temporary Installations: Construction site wiring (with additional protection)
Key Advantages
Cost-Effective: Affordable solution for fixed electrical installations
Easy to Install: Rigid design simplifies routing and termination
Wide Availability: Commonly used and readily available in various sizes
BV cable is ideal for general-purpose fixed wiring applications. For flexible needs, consider BVR (flexible copper conductor), or for enhanced fire safety, NH-BV (fire-resistant). Customizable conductor sizes (1.5-400 mm²) are available. Consult technical datasheets for details.
Low Voltage BV Cable (≤1kV)
Main Use
Standard power and lighting circuits in residential, commercial, and industrial buildings.
Power supply to air conditioners, refrigerators, and lighting systems
Office buildings, schools, hospitals, and shopping centers
Common Rating
450/750V or 300/500V
Frequently Asked Questions
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 worldwide.
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
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.
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
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.
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.
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.
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.
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.
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.
