YJV and BVV are both cable types, suitable for outdoor lighting and power transmission. BVV cables are copper-core PVC insulated and PVC sheathed round cables (wires). YJV cables are cross-linked polyethylene insulated and PVC sheathed power cables. Let's take a look at their specific differences.
What are the differences between BVV and YJV cables?
1. Voltage Differences
BVV copper-core PVC insulated and PVC sheathed connecting cables have a voltage rating of 300/500V. YJV cross-linked polyethylene insulated and PVC sheathed power cables have voltage ratings of 0.6/1kV for low voltage, 6/10kV for medium voltage, and 26/35kV for high voltage.
2. Different Structures
BVV sheathed cable is a commonly used cable in weak current systems. It consists of two or more BV wires with an outer sheath. Single-core cables are round, while double-core cables are flat. The internal cores are available in 2-core, 3-core, 4-core, 5-core, 3+1-core, 3+2-core, 6-core, and 7-24-core sizes. YJV cross-linked cable basically consists of conductors, insulation, and a sheath. Shielding and armoring layers may be added for special requirements. YJV internal cores are available in 1-core, 2-core, 3-core, 4-core, 5-core, 4+1-core, 3+2-core, and 3+1-core sizes.
3. Different Characteristics
BVV is a type of household wiring cable, designated by the letter "B." It is resistant to acids, alkalis, oils, moisture, and mildew. The permissible operating temperature must not exceed 65°C. Nationally standardized BVV cables must carry the CCC certification mark.
YJV is a type of power cable. The long-term operating temperature for ordinary cables should not exceed 70°C, while for cross-linked cables, it should not exceed 90°C. It offers excellent electrical performance. Multi-core cables feature a compact, flattened design, offering structural stability, light weight, and a small outer diameter.
What are the differences between BVV and YJV cables?
BVV cables are suitable for power cables for electrical appliances with a rated power frequency voltage of 300/500V or below. They are commonly used for surface-mounted wiring, such as household appliances, lighting circuits, and electrical equipment. YJV cables are suitable for fixed installation in distribution networks or industrial installations with a rated power frequency voltage of 0.6/1kV or above, such as urban power grids, mines, and large factories.
The above is about the difference between YJV cable and BVV cable. I believe everyone has some understanding of the differences and advantages of the two. YJV cable and VV cable are basically the same in function, but the product names are different and represent different meanings: YJV cable is named after cross-linked polyethylene insulated PVC sheathed power cable, and BVV cable is named after copper core PVC insulated PVC sheathed round cable (wire). We can choose according to our actual needs.
