Do you know the difference between YJV22 and YJV23?
YJV22 and YJV23 cables are one of the most common cable models we usually use. Do you know the meanings of their letters and numbers? YJ stands for cross-linked polyethylene, V stands for polyvinyl chloride, 2 steel belt armor, and 2 stands for polyvinyl chloride outer sheath (PVC). YJV22 refers to cross-linked polyethylene insulation, polyvinyl chloride cushion layer (extruded or wrapped), steel belt armor, and polyvinyl chloride sheath. The YJ in YJV23 stands for cross-linked polyethylene, V stands for polyvinyl chloride, 2 steel belt armor, and 3 stands for polyethylene outer sheath (PE). So YJV23 refers to cross-linked polyethylene insulation, polyvinyl chloride cushion layer (extruded or wrapped), and steel belt armor. Polyvinyl chloride sheath.
What are the differences between YJV23 cable and YJV22 cable? First of all, the outer sheath material is different: the outer sheath material of YJV22 is polyvinyl chloride (PVC), and the outer sheath material of YJV23 is polyethylene (PE). In simple terms, it is the difference between PVC and PE.
The difference between these two materials is that polyvinyl chloride (PVC) is a hard plastic, commonly used in industrial fields. Polyethylene (PE) feels waxy, is lighter than similar plastics, and has a certain degree of transparency. The difference in application is that PVC is mostly used in general products in the wire and cable industry because of its good physical and mechanical properties, good processing performance, low cost and selling price. But it contains halogens, and the sheath is used the most. PE is often used for wire or cable insulation and data line insulation. It has a low dielectric constant and is suitable for data lines, communication lines, and various computer peripheral wire core insulation. YJV22 and YJV23 each have their own application scenarios and differences, so we must choose the most suitable product when selecting.
