What's the difference between VVR and AVVR? While VVR and AVVR cables may look nearly identical, there are substantial differences. RVV cable stands for copper-core PVC insulated and sheathed flexible cable, also known as lightweight PVC sheathed flexible cable or soft-sheathed cable. It's a type of sheathed cable. It's primarily used for power lines, control lines, and signal transmission lines in electrical appliances, instruments, electronic equipment, and automation devices. Specifically, it can be used in burglar alarm systems and building intercom systems. VVR and AVVR also differ in voltage levels and applications. Let's take a closer look.
1) VVR is a copper-core PVC-insulated and sheathed flexible power cable with a voltage rating of 0.6/1kV. Each copper wire has a diameter of approximately 0.2-0.3mm and is relatively numerous, making it relatively flexible and suitable for power cables that are frequently moved.
2) VVR—This is a copper-core, PVC-insulated, PVC-sheathed, flexible power cable. It's a derivative of the VV power cable and is suitable for transmitting continuous current in distribution networks or industrial electrical equipment with an AC rated voltage U0/U/ of 600/1000V or less. Its manufacturing standard is GB/T 12706.
Differences between VVR and AVVR
1) Voltage Level
RVV is a flexible cable with a rated voltage of 300/500V. The cable conductor cross-section is generally between 0.5-2.5mm², and the number of cores is 2-5.
VVR, on the other hand, generally has a voltage level of 0.6/1kV and the same structure as VV. The conductor cross-section ranges from 1.5-630mm². For the same cross-sectional area and number of cores, the outer diameter of the VVR is slightly larger than that of the RVV.
2) Different Structures
The VVR has the same structure as the VV cable and is a type of power cable.
AVVR is a type of sheathed cable. The A designates installation cable.
3) Different Applications
VVR is suitable for frequently moved power cords, such as computer power cords.
AVVR flexible cables are suitable for multi-core low-voltage security cables and electrical equipment connections.
4) Different Implementation Standards
VVR Manufacturing Standard Reference: GB/T 12706-2008
AVVR Implementation Standard Reference: JBB734-4-1998 AVVR Flexible Cable Models
Some AVR models include:
AVR Copper Core PVC Insulated Flexible Installation Cable
AVRS Copper Core PVC Insulated Stranded Flexible Installation Cable
AVRB Copper Core PVC Insulated Flat Flexible Installation Cable
Although the model numbers may not appear to be significantly different, the differences between the two are substantial. Furthermore, their voltage ratings differ, and their intended applications differ. Therefore, these differences between the products represent a form of complementary strength, allowing you to choose the best fit based on your strengths and needs.
