Whether it is wire or cable, different letters represent different meanings. For example, RVV is a cable, and RV is a wire, so what's the difference between the two?

In fact, these two types of wire and cable are power cables, but these two types of wire and cable are different in terms of use, conductor structure, bushing, rated voltage and so on.


1. Different product names

RV is the model of wire and cable, the full name is copper core polyvinyl chloride insulated connection soft wire and cable. RV wire and cable with soft structure design, conductor bending radius is small, and suitable for wet and oily installation sites.

The full name of RVV cable is copper core PVC insulated PVC sheathed flexible cable, also known as light PVC sheathed flexible wire, commonly known as soft sheathed wire, it is a kind of sheathed wire. In fact, RVV wire and cable is two or more RV lines with a layer of sheath.

2, rated voltage is different

The rated voltage of the RV wire is 450/750V and the rated voltage of the RVV wire is 300/500V.

3, the core structure is different

RV wires are single-core (multiple) copper wires, while RVV wires are multi-core copper wires made from two or more RV wires.

4, the sheath structure is different

There is no protective sheath layer outside the RV line, and there is a layer of PVC sheath outside the RVV line, the main function is to protect the internal protective layer of the cable from mechanical extrusion and chemical corrosion, and play a tensile and compressive, anti-oxidation role.

5. Different colors

The color of RV wire is red, blue, white, green, brown, gray, black, etc. RVV wire generally has black and white.

6. Different uses

RV wire has a wide range of applications in the field of industrial power distribution, especially suitable for more stringent flexible installation sites, such as electric control cabinets, distribution boxes and various low-voltage electrical equipment, can be used for power, electrical control signals and switching signals transmission.

RVV wire is mainly used in electrical, instrumentation and electronic equipment and automation equipment with power lines, control lines and signal transmission lines, specifically can be used in anti-theft alarm system, building intercom system, etc.

Qingdao Tianxing Cable Co., Ltd. focuses on the production of customized wire and cable manufacturers, main: fire wire and cable, power cable, control cable and other products, exported to more than 40 countries and regions around the world, the annual production capacity of 1 billion yuan. 6000 square meters of storage, standing hundreds of millions of inventory, order demand for rapid distribution and delivery, large prices more favorable.
