RVV Cable Product Introduction
RVV cable is called copper-core PVC insulated PVC sheathed soft wire, also known as light PVC sheathed soft wire, commonly known as soft sheathed wire, is a kind of sheathed wire. The rated voltage is 300V/500V, and the number of cores is divided from 2 cores to 24 cores according to the national standard. Two or more copper cores are twisted to form a cable, the outer direction of the strangulation direction is right.
RVV cable is mainly used in power lines, control lines and signal transmission lines for electrical appliances, instruments and electronic equipment and automation devices, and can be used for anti-theft alarm systems and building intercom systems.
The meaning of the RVV letter:
The letter R stands for soft wire;
The letter V stands for insulator polyvinyl chloride (PVC);
RVV cable is the most commonly used cable in weak electric system. The core cable has two or more core wires. There is an PVC sheath outside, and there is no special requirement for the arrangement of core wires.
The function of RVV cable sheath:
For example, 1: RV v2 0. 5 is two 0. 5 square millimeters of wire plus an outer sheath. The effect of the sheathing is:
1.Protect the inner layer of cable from mechanical damage and chemical corrosion;
2.Enhance the mechanical strength of the cable.
RVV refers to the multi-strand copper core soft wire, the logo on the outer viewing line, the comparative thickness of the cortex and core. The sheath skin is generally a polychlorinated material. The copper core is 19 strands. The specifications are generally 1,1.5,2.5 square millimeters. Then look at the length of the line (one circle is 100 meters), the national standard line is 95-100 meters, non-standard The line is about 90 meters.
