The Chinese names for YJV, YJY, and VV cables are very similar, and many customers are confused about the differences and don't know how to choose. Reading the following article will help you gain a clearer understanding of these three types.
1. Differences in Names:
YJV stands for Copper Core, Cross-Linked Polyethylene Insulated, Polyvinyl Chloride Sheathed Power Cable
YJY stands for Copper Core, Cross-Linked Polyethylene Insulated, Polyvinyl Chloride Sheathed Power Cable
VV stands for Copper Core, Polyvinyl Chloride. Comparing the names reveals that YJV and VV cables differ from YJY cables in their outer sheath materials: YJY cables use polyethylene (PE), while YJV and VV cables use polyvinyl chloride (PVC). The insulation materials of YJY and YJV cables differ from those of VV cables: YJY and YJV cables use polyethylene (PE), while VV cables use polyvinyl chloride (PVC).
2. Application Differences:
Because YJV cables are made of polyvinyl chloride (PVC) as their outer sheath material, which produces harmful gases when burned, they are not suitable for use in populated areas or enclosed spaces. YJV cables are primarily used in urban underground power grids and power station outlet lines. YJY cables are suitable for use in subway stations, large shopping malls, and other areas.
3. Price Comparison:
The sheath cost of YJY cables is slightly higher than that of YJV cables, so YJY cables of the same specifications are more expensive than YJV cables. VV cables have lower performance than YJV cables, so many other brands of VV cables are slightly cheaper than YJV cables.
4. Operating Temperature Differences:
The operating temperature of the conductors of both YJY and YJV cables cannot exceed 90°C, while that of VV cables cannot exceed 70°C. The operating temperature range for YJV and VV cables is -20°C to +45°C, while that for YJY cables is -40°C to +45°C.
5. Voltage Differences:
VV cables are low-voltage cables and can only be used in low-voltage environments. YJY and YJV cables, on the other hand, offer both low-voltage and medium- and high-voltage applications, thus offering a wider range of applications.
