What's the RVV electric wire & cable ?
RVV wire and cablefull copper core PVC insulated PVC sheathed flexible wire, also called light PVC sheathed flexible cord, commonly known as soft sheath line, is one of the sheath line. Mainly used in electronics, instruments and electronic equipment and automation devices in the power cord, the line of control and signal transmission lines, concrete can be used for anti-theft alarm system, building intercom system, etc.
RVV wire Rated voltage 300V/500V, cores from the core 2 to 24 between the core by the separation of GB, with more than two core stranded cable, outer stranding direction right to widely used in instruments, meters, building intercom, monitoring control installation
Letter R stands for: soft wire
Letter V representative: polyvinyl chloride (PVC)
RVV electric wire is the most commonly used cable system, the number of core wire is not fixed, two or more, there is a PVC sheath outside, there is no special requirements between the core line.
Protective effect of sheath
For example: rvv2*0.5 is the 0.5 2 square mm line plus a layer of outer sheath, the role of the sheath is
1, the protection of the protection of the cable layer from mechanical damage and chemical corrosion;
2, enhance the mechanical strength of the cable.
RVV wire refers to multi strand copper cord, look look at online identification, cortex and core thickness compared. Cortex is generally polyvinyl chloride material. Copper core is 19 stranded. General specifications have 1,1.5,2.5 square mm in length (around 100 meters), 95-100 meters GB line, non marking 90 meters left and right line
