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 is better than VV cable in terms of temperature, voltage and corrosion resistance. VV cable is PVC insulated PVC sheathed, thermoplastic material, YJV cable is cross-linked PVC insulated PVC sheathed, thermosetting material, it is because of the material difference, so VV and YJV cable allows long-term work at higher temperatures are different. 1. VV cable (VLV) cable conductor operation at a higher rated temperature of 70 degrees Celsius, short-circuit (duration of less than 5 seconds) higher temperature, short-circuit (short-circuit). 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 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.
