RVV rated voltage 300/500V soft wire, cable conductor cross-section is generally between 0.5-2.5, cable core number 2-5 core, manufactured according to national standard GB/T 5023-2008.
The voltage levels and applications are different.
RVV rated voltage 300/500V soft wire, cable conductor cross-section is generally between 0.5-2.5, the number of cable cores 2-5 cores, the implementation of national standard GB/T 5023-2008 standard production.
VVR generally has a voltage level of 0.6/1kV, the same structure as VV, conductor cross-section from 1.5-630mm2, cable core number 1-5 core manufacturing standard GB/T12706-2008.
VVR soft cable introduction
VVR is a core polyvinyl chloride insulated and sheathed soft structure power cable, voltage level 0.6/1KV. The diameter of each copper wire is about 0.2-0.3mm, the number of roots is relatively large, so it is relatively soft, suitable for frequently moving power lines.
【RVV wire】The full name is: copper core polyvinyl chloride insulated polyvinyl chloride sheathed soft wire, also known as light polyvinyl chloride sheathed soft wire, commonly known as soft sheathed wire, is a kind of sheathed wire. The two letters V represent that the insulation and sheath materials are both polyvinyl chloride. RVV wire is the most commonly used cable in weak current systems. The number of core wires is uncertain, two or more, with a PVC sheath outside. The number of cores ranges from 2 to 24, color-coded according to national standards. Two or more cores are stranded into a cable, and the outer layer stranding direction is right-handed. There is no special requirement for the arrangement between the core wires.
【Main uses】Used in electrical appliances, instruments and electronic equipment and automatic devices for power lines, control lines and signal transmission lines, specifically used in anti-theft alarm systems, building intercom systems, instruments, meters, monitoring and control installation, etc.
Among them, copper (aluminum) core polyvinyl chloride insulated polyvinyl chloride sheathed power cable (RVV wire) is an important member of power cables, so it belongs to the power cable (power cable) series.
