RVV Wire Overview
According to the provisions of GB 5023.5-1997, RVV refers to the light polyvinyl chloride sheathed flexible wire or ordinary polyvinyl chloride sheathed flexible wire, the rated voltage level of 300/300 and 300/500, respectively, the rated voltage 250V/450V
RVV wire and cable is more than two cores of PVC insulated PVC sheathed flexible wire (two or on the rv line plus a layer of sheath). rvv wire is the most commonly used cable for weak power systems, the number of cores is not certain, two or more, outside the PVC sheath, the number of cores from 2 cores to 24 cores of the color according to the national standard (7 cores and above can be digitally coded), more than two cores stranded into a cable, the direction of the outer layer of stranded to the right! There is no special requirement for the arrangement between the cores.
Role
1】Protect the cable inner sheath from mechanical damage and chemical corrosion; 【1】Protect the cable inner sheath from mechanical damage and chemical corrosion.
2】Enhance the mechanical strength of the cable.
Model Description
For example: RVV2 * 1.5 2 is 2 cores, 1.5 indicates a core cross-section area (unit is square millimeter)
Main use
Applied to electrical appliances, meters and electronic equipment and automatic generation of devices with power lines, control lines and signal transmission lines, specifically can be used for burglar alarm systems, building intercom systems, instruments, meters, surveillance monitoring control installation.
