When it comes to wires and cables, the most common ones people know about are household BV and BVR cables. However, what is RVB red-black cable? Why is it called RVB red-black cable? RVB, commonly known as red-black (parallel) cable, is a flat, unsheathed flexible cable. It is made of a red and a black insulated copper wire extruded in parallel, hence the name. Red is typically the positive pole, and black is the negative pole. The difference between RVB and RVVB and RVS cables is a frequently discussed topic.
The meaning of RVB red-black cable
RVB stands for two-core flat copper core polyethylene insulated flexible cable. It is a flat, unsheathed flexible cable commonly used for internal installations, such as those used in household appliances, small power tools, and power lighting. The ambient temperature during installation should be no lower than -15°C.
1) Meaning of Wire Letters
R stands for flexible wire (conductor structure)
V stands for polyvinyl chloride (sheath material)
B stands for parallel (wire shape)

Differences between RVB, RVVB, and RVS
1) Differences between RVB and RVS
① RVS is a twisted-pair flexible cable. The difference between the two is that RVB uses parallel copper wires, while RVS uses twisted-pair copper wires.
②RVS is a copper-core, PVC-insulated, twisted, flexible cable for connection; it's suitable for household lighting, appliances, instruments, radio and audio control wiring, fire protection wiring, and more.
③RVS is a twisted-pair flexible cable, while RVB is a flat flexible cable. Both are unsheathed and have different uses and functions.
2) Differences between RVB and RVVB
①RVB wire and cable: RVVB is a copper-core, PVC-insulated, sheathed, flat power cable suitable for household appliances, lighting, security monitoring, and more. RVB and RVVB are both flat parallel cables with the same application, but RVB is a flat, unsheathed flexible cable, while RVVB is a flat, sheathed flexible cable, meaning RVVB has an additional sheath.
②RVB and RVVB are both flat parallel cables with the same application, but RVB is a flat, unsheathed flexible cable, while RVVB is a flat, sheathed flexible cable, meaning RVVB has an additional sheath.
From this, we can see that although there are slight differences in the types and specifications of wires, their application scopes are similar. For example, the above three types can be used in household appliances, lighting, instruments, radio and audio connection control wires, fire protection cables, security monitoring connection wires, etc. Many specifications and models of wires are widely used, so they will not limit our purchasing needs.
