Everyday electrical wires like RVS, RV, RVV, RVVP, RVP, and RVB all begin with the letter "R." While they might appear similar at first glance, there are actually significant differences between each model.
So, what does "R" actually stand for? What are the relationships and differences between these wire types?
First, let's talk about the letter "R."
"R" stands for the pinyin initials of the Chinese character for "soft," meaning "soft copper conductor," indicating that the wire is a soft wire.
It's easy to see that all of the above wires are soft wires.
Now let's talk about the various types.
1. RVS
The "V" is the abbreviation for PVC, which stands for polyvinyl chloride insulation, and the "S" stands for twisted pair.
RVS stands for Copper Core Polyvinyl Chloride Insulated Twisted Pair Connecting Wire, also known as "twisted pair" or "flexible wire."
Internal Structure: Multiple strands of fine copper wire twisted together, insulated, and then twisted together to form two intertwined insulated cores.
Applications: Suitable for automatic fire alarm systems, household appliances, small power tools, instruments, and power lighting cables.
2. RV
The "V" stands for PVC, which stands for polyvinyl chloride insulation.
RV stands for: Copper-core PVC-insulated flexible cable for connecting wires.
Internal Structure: A single-core cable consisting of many fine copper strands twisted together. It has a simple structure and is easy to bend and install.
Applications: Particularly suitable for installations requiring strict flexibility, such as control cabinets, distribution boxes, and various low-voltage electrical equipment.
3. RVV
The first "V" stands for PVC insulation, and the second "V" stands for PVC sheath.
RVV stands for: Copper-core PVC-insulated PVC-sheathed flexible cable.
Internal Structure: A flexible sheathed cable consisting of two or more RV wires nested together.
Applications: Primarily used in electrical appliances, instruments, electronic equipment, and automation devices. It is particularly common in burglar alarm systems and building intercom systems.
4. RVVP
The first "V" stands for PVC insulation, the second "V" stands for PVC sheath, and the letter "P" stands for shielding.
RVVP stands for Copper Core PVC Insulated PVC Sheathed Shielded Flexible Cable.
Internal Structure: Two or more RV wires are sheathed together, with an external shielding layer and PVC outer sheath.
Applications: Suitable for communications, audio, broadcasting, sound systems, burglar alarm systems, intelligent automation systems, automatic meter reading systems, fire protection systems, and other applications requiring interference-resistant line connections and efficient and secure data transmission.
5. RVP
The "V" stands for PVC insulation, and the "P" stands for shielding.
RVP stands for Copper Core PVC Insulated, Shielded, and Sheathed Flexible Cable.
Internal Structure: Made of many strands of fine copper wire, twisted together, with PVC insulation, shielding, and an outer PVC sheath.
Applications: Commonly used in applications requiring interference-resistant line connections, such as communications, audio, broadcasting, and sound systems, as well as those requiring high signal transmission quality.
6. RVB
The "V" stands for PVC insulation, and the "B" stands for flat cable.
RVB stands for Copper Core PVC Insulated, Flat, Unsheathed Flexible Cable, commonly known as "Red and Black (Parallel) Cable."
Internal Structure: Two multi-strand copper core wires, red and black, are extruded in parallel. Red typically represents the positive pole, and black represents the negative pole.
Applications: Widely used in household lighting, electrical appliances, small power tools, instrumentation, broadcast and audio control wiring, fire protection wiring, and other applications.
7. RVVB
The first letter "V" stands for PVC insulation, the second letter "V" stands for PVC jacket, and the letter "B" stands for flat.
RVVB stands for: Copper Core PVC Insulated and Sheathed Flat Flexible Wire
Internal Structure: RVB wire with a parallel extruded PVC outer jacket.
Applications: Suitable for household appliances, lighting, and security monitoring cables.
