YJV cable and VV cable what is the difference between these two kinds of power cable

YJV and VV are two kinds of power cables with different insulation materials. Generally indoor projects tend to choose YJV cable, VV cable is generally used in low-voltage systems more, YJV cable is used in high-voltage systems. YJV cable in the temperature, pressure, corrosion resistance are better than VV cable. Only the price is more expensive.
VV cable is PVC insulated PVC sheath, is a thermoplastic material, YJV cable is cross-linked PVC insulated PVC sheath, is a thermosetting material, it is because the material is different, so the VV and YJV cables are allowed to work for a long time at higher temperatures are different.
1.VV cable (VLV) class cable conductor operation higher rated temperature of 70 degrees Celsius, short-circuit (duration of less than 5 seconds) higher temperature does not exceed 160 degrees Celsius.
2.YJV cable (YJLV) class cable conductor operation at a higher rated temperature of 90 degrees Celsius, short-circuit (duration of less than 5 seconds) higher temperature does not exceed 250 degrees Celsius. So the two kinds of cables have different current-carrying capacity, YJV larger.
