1. YJV insulation uses cross-linked polyethylene. VV insulation uses polyvinyl chloride.
2. YJV cable has an operating temperature of up to 90°C, while VV only has a temperature of 70°C. YJV cable has a higher current carrying capacity for the same cross-sectional area.
3. The maximum operating temperature rating for VV cable conductors is 70°C, and the maximum temperature during a short circuit (lasting less than 5 seconds) does not exceed 160°C.
4. The maximum operating temperature rating for YJV cable conductors is 90°C, and the maximum temperature during a short circuit (lasting less than 5 seconds) does not exceed 250°C.
5. YJV is superior to VV in the long run (due to longer service life, etc.), but it is more expensive.
6. From a technical and economic perspective, three-core YJV cables have higher parameters than VV cables.
7. YJV is recommended for use in residential buildings because it has a higher current carrying capacity than VV cables. More importantly, in the event of an electrical fire, since its insulation material does not contain chlorine, it does not produce toxic gases when burned.
