What is the difference between RV and RVV?

18-10-2024

Recently, many customers who in lighting industry have been asking about our RV and RVV wires. RV and RVV only differ by a letter V, so what is the difference? Although both RVV and RV are soft wires, the two types of wires are different in terms of rated voltage, conductor structure, color, etc. Below, we, the wire and cable manufacturer, will take you to understand.

RV wire

1. The product names are different. RV is a general-purpose single-core soft conductor unsheathed cable, and RVV is a copper-core PVC insulated PVC sheathed soft cable.

2. The rated voltages of the two are different. The rated voltage of RV wires is 450/750V, while the rated voltage of RVV wires is 300/500V.

3. The wire core structure is different. RV wires are single-core (multi-branch) copper wires, while RVV wires are multi-core copper wires, which are made of two or more RV wires.

4. The sheath structure is different. There is no sheath layer outside the RV wire, but there is a PVC sheath outside the RVV wire. The main function is to protect the internal protective layer of the cable from mechanical extrusion and chemical corrosion, and to resist tension, compression and oxidation.

5. The colors of the two are different. The colors of RV wires are red, blue, white, green, brown, gray, black, etc., and RVV wires are generally black and white.

6. The main uses are also different. RV wires are widely used in the field of industrial power distribution, especially suitable for flexible installation sites with strict requirements, such as electric control cabinets, distribution boxes and various low-voltage electrical equipment. They can be used for the transmission of power, electrical control signals and switch signals. RVV wires are mainly used for power lines, control lines and signal transmission lines for electrical appliances, instruments and electronic equipment and automation devices. Specifically, they can be used for anti-theft alarm systems, building intercom systems, etc.

RVV wire

To sum up, we can see the difference between RVV and RV wires. We can choose wires and cables according to our actual needs. Wire and cable manufacturers hereby remind users that when purchasing cables, please verify whether the product has the national mandatory CCC certification and whether the merchants various certificates are complete to ensure the safe and stable operation of wires and cables.
