[Cable Encyclopedia] RVV Has Just One More "V" Than RV Wire, What's the Difference Exactly?

The Difference Between RV and RVV

Although both RVV and RV are flexible wires, there are many differences between these two types of wires in terms of rated voltage, conductor structure, color, etc. Now, I will introduce them to you in detail.

Different Product Names
RV is a single - core flexible conductor non - sheathed cable for general purposes, while RVV is a copper - core PVC insulated and PVC sheathed flexible cable.

Different Rated Voltages
The rated voltage of RV wire is 450/750V, while that of RVV wire is 300/500V.

Different Core Structures
RV wire is a single - core (multi - strand) copper wire, while RVV wire is a multi - core copper wire made of two or more RV wires.

Different Sheath Structures
RV wire has no protective sheath layer outside, while RVV wire has a layer of PVC sheath outside, which mainly functions to protect the internal protective layer of the cable from mechanical extrusion and chemical corrosion, and has the functions of tensile resistance, compression resistance and oxidation resistance.

Different Colors

The colors of RV wire include red, blue, white, green, brown, gray, black, etc., while the conventional colors of RVV wire are black and white.

Different Main Uses

RV wire is widely used in the field of industrial power distribution, especially suitable for flexible installation sites with more stringent requirements, such as electric control cabinets, distribution boxes and various low - voltage electrical equipment, and can be used for the transmission of power, electrical control signals and switch signals.
RVV wire is mainly used for power cords, control lines and signal transmission lines of electrical appliances, instruments, electronic equipment and automation devices, and can be specifically used in anti - theft alarm systems, building intercom systems, etc.

In conclusion, we can clearly see the difference between RVV and RV wires. When choosing wires and cables, we can make a selection according to our actual needs. Here, I would like to remind the majority of users that when purchasing cables, please be sure to verify whether the product has the national mandatory CCC certification and whether the various certificates of the merchant are complete to ensure the safe and stable operation of the wires and cables.
