RVV sheathed cable specifications primarily include the number of cores and the conductor cross-sectional area. Common specifications are as follows:
Number of Cores
RVV sheathed cable typically has 2, 3, 4, 5, 6, 7, 8, 10, or 12 cores.
Conductor Cross-sectional Area
Common conductor cross-sectional area specifications include: 0.12mm², 0.2mm², 0.3mm², 0.5mm², 0.75mm², 1.0mm², 1.5mm², 2.5mm², 4.0mm², and 6.0mm².
Specific Model Examples
RVV2*0.5: Indicates 2 cores, each with a conductor cross-sectional area of 0.5mm².
RVV3*1.0: Indicates 3 cores, each with a conductor cross-sectional area of 1.0mm².
Application Scenarios
RVV sheathed cable is widely used in appliances, instruments, electronic equipment, automation devices, burglar alarm systems, building intercom systems, and other applications.
Other Features
Rated Voltage: Typically 300/300V or 300/500V.
Conductor Material: Multi-core annealed bare copper stranded.
Sheath Material: Polyvinyl chloride (PVC).
Differences Between RVV and RVVB
The main difference between RVV and RVVB lies in their design: RVV is a round cable, while RVVB is a flat cable.
1. Design
RVV: Round cable, compact, sleek, and resistant to damage.
RVVB: Flat cable, with its flat design, offers greater flexibility during wiring and saves space.
2. Application Scenarios
RVV: Widely used for power, control, and signal transmission lines in electrical appliances, instruments, electronic equipment, and automation devices, such as burglar alarm systems, building intercom systems, and surveillance systems.
RVVB: Similar to RVV applications, due to its flat design, it is particularly suitable for applications requiring a flat layout, such as audio and video signal connections for audio equipment and home video equipment.
3. Structural Features
RVV: Made of multiple strands of twisted copper wire, covered with a PVC insulation layer and a PVC jacket. The number of cores ranges from 2 to 24.
RVVB: Also made of multiple strands of twisted copper wire, but with a flat jacket design, it is generally a two-core jacketed cable.
4. Performance and Safety
RVV: Rated voltage is generally 300V/500V, with a long-term operating temperature not exceeding 70°C. It offers excellent electrical safety and stability.
RVVB: The rated voltage and working environment are similar to RVV, but the sheath thickness is thinner, and the tensile and compressive resistance are not as good as RVV. Attention should be paid to the symmetry and uniformity of the cable structure.
