YJV and YJY cables have similar names, so what's the difference between them?
Material Differences:
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
YJY and YJV Structure Diagram
As the full names indicate, these two cables differ only in the outer sheath material; all other structural layers and materials are the same. The outer sheath material of YJY cable is polyethylene (PE), while that of YJV cable is polyvinyl chloride (PVC). Chlorine combustion produces gases that are harmful to the human body, so chlorine-containing YJV cables are not suitable for use in crowded places.
YJV Cable
Application Differences:
YJV cables are primarily used for the transmission and distribution of power cables and are commonly used in urban underground power grids and power station outlet lines.
YJY cables are suitable for use in enclosed and crowded places, such as subway stations, large shopping malls, and larger underground business halls.
Price Differences:
YJY cable sheaths are made of polyethylene (PE), while YJV cable sheaths are made of polyvinyl chloride (PVC). PE is more expensive than PVC, resulting in a slightly higher cost for YJY cables.
YJY Cable
Operating Temperature Differences:
Both YJY and YJV conductors must operate at temperatures exceeding 90°C. The operating ambient temperature for YJV is -20°C to +45°C, while the operating ambient temperature for YJY is -40°C to +45°C.
Performance Differences:
YJY cables offer better low-temperature resistance than YJV cables.
