What does cable YJV mean?
YJV cable refers to a high-quality copper core cross-linked polyethylene insulated polyvinyl chloride sheathed power cable, and its full English name is PVC Insulated and Sheathed Power Cable.
Y indicates that the insulation material of the cable is cross-linked polyethylene (XLPE)
J indicates that its armor material is single-layer steel wire armor (SWA)
V indicates that the sheath material of the cable is polyvinyl chloride (PVC)
YJV cable is mainly used in power transmission and distribution systems. It can be directly buried in the soil or placed on overhead brackets. It can also be used for laying indoors, in pipelines, caves or cable trenches.
Due to its compact structure, good insulation performance, poor conductivity, high mechanical strength and long service life, YJV cable is widely used in power systems in construction, mining, power, chemical and other industries.
YJV cable and YJY cable, although they have similar names, there are differences in some aspects, so what is the difference between them?
Difference in materials used:
The full name of YJV is copper core cross-linked polyethylene insulated polyvinyl chloride sheathed power cable
The full name of YJY is copper core cross-linked polyethylene insulated polyethylene sheathed power cable
From the full name, it can be seen that the two cables only have different outer sheath materials, and the other structural layers and materials are the same. The outer sheath material of YJY cable is polyethylene (PE), and the outer sheath material of YJV cable is polyvinyl chloride (PVC). Chlorine combustion will produce gases that are harmful to the human body, so chlorine-containing YJV cables are not suitable for places where many people gather.
Difference in scope of application:
YJV cables are mainly used for the transmission and distribution of power cables, and are often used in urban underground power grids, export lines of power stations, etc.
YJY cables are suitable for closed and densely populated places, such as subway underground stations, large shopping malls, larger underground business halls, etc.
