The full name of RVV cable is copper core PVC insulated PVC sheathed flexible cable, also called light PVC insulated poly, commonly known as soft sheathed wire, which is a kind of sheathed wire. RVV wires and cables are two or more RV wires plus a layer of sheath. RVV cable is the most commonly used cable for weak current systems. The number of core wires is variable, two or more, and there is a PVC sheath on the outside. The letter R stands for flexible cord and the letter V stands for insulator polyvinyl chloride (PVC)
Cable full name copper core PVC insulated PVC sheathed flexible cable
Lightweight PVC insulated poly
Soft sheath line
The rated voltage is 300V / 500V, the number of cores is divided according to the national standard from 2 to 24 cores, and the two or more cores are twisted into a cable. Control installation cable.
RVV full name
Copper core PVC insulated PVC sheathed flexible cable.
What the letters mean
The letter R stands for flexible cord
The letter V stands for insulator polyvinyl chloride (PVC)
The rvv wire is the most commonly used cable for weak current systems. The number of core wires is variable, two or more, and there is a PVC sheath on the outside. There is no special requirement for the arrangement of the core wires.
The role of the sheath
For example: rvv2 * 0.5 is two 0.5 square millimeter wires plus a layer of outer sheath. The role of the sheath is
1.Protect the inner sheath of the cable from mechanical damage and chemical corrosion;
2. Enhance the mechanical strength of the cable.
RVV refers to a multi-strand copper core cord, the logo on the outside of the line, and the comparable thickness of the skin layer and the core. The skin layer is generally a polyvinyl chloride material. The copper core is 19 strands. When looking at the length of the line (one roll is 100 meters or 200 meters), the length error of the national standard line is required to be within 5%, and the error of many non-standard lines is about 10%.

Application of RVV cable
RVV cable is mainly used in flexible applications such as medium and light mobile appliances, instruments, household appliances, power lighting, etc. It can transmit control signals and power signals. It is also suitable for laying in bridges and hoses. At the same time, this product has obtained the CCC and CE mark certifications, and complies with the requirements of HD (European Union Harmonized Standard). It can be applied not only to the Chinese market, but also to the European market. According to the HD standard, this cable model is H05VV-F.
