The full name of RVV wire is copper core PVC insulated PVC sheathed flexible wire, also known as lightweight PVC sheathed flexible wire, commonly known as soft sheathed wire, which is a type of sheathed wire. The rated voltage is 300V/500V, and the number of cores ranges from 2 to 24 according to national standards. Two or more cores are twisted into a cable, with the outer layer twisted in the right direction. It is widely used in the control and installation of instruments, meters, building intercoms, and monitoring.
The main purpose of RVV wires
Suitable for controlling signal transmission lines, electrical equipment, instruments, automation equipment, security and anti-theft alarm systems, high-rise building intercom systems, household lighting connection lines, etc. The function of RVV wire sheath is to protect the inner protective layer of the cable from mechanical damage and chemical corrosion, and enhance the mechanical strength of the cable.

Daily maintenance of RVV wires
1. Be careful not to use the power cord in heat sources or humid environments with temperatures greater than 50 degrees Celsius. Otherwise, over time, the surface is prone to damage, and once the sheath is damaged, the core inside will also have problems.
2. It is best to avoid direct sunlight on the power cord plug, as it can shorten the lifespan of the power cord. Therefore, when wiring, the power cord plug should still be placed in a place without direct sunlight.
3. If you want to move the power cord, avoid pulling it too hard, otherwise it is easy to damage or even break the copper wire inside. Also, do not excessively wrap or bend it too much, otherwise it will also cause breakage.
Advantages of RVV wires
1. High purity oxygen free copper
Low resistance, high current carrying capacity, stable and efficient, energy-saving, high safety factor, and good conductivity.
2 High quality one-time flame retardant insulation materials
The insulation is made of high-quality PVC material, which is wear-resistant, not easy to crack or age, and always maintains good insulation performance, which can better ensure the safety of users' use.
3 Low Eccentricity
Adopting advanced production equipment and processes, strict procedures ensure uniform thickness of the insulation layer, effectively prevent current breakdown and ignition, and achieve higher conductivity.
4. Structural stability
The tension of the insulated wire core is consistent, the cable core is round and round, the filling is full and tight, and it is safe and reliable.
5 foot cores, foot meters
The number and cross-section of conductor cores shall be strictly produced in accordance with national standards, with no shortage of meters or short meters, and no false length markings. The surface of the wire shall be printed with meter markings.
6 rolls guarantee no joints
There are no joints in the middle of each coil of wire, avoiding open circuits caused by joints, ensuring contact resistance, insulation performance, and tensile strength meet the requirements for use and safety, and saving threading time.
