YJVPower cables are superior in temperature resistance, voltage resistance, and corrosion resistanceVVPower cables. It's just more expensive.YJVCopper core cross-linked polyethylene insulated polyvinyl chloride sheathed power cable.
VV-Copper core PVC insulated PVC sheathed power cable.

YJVVoltage level（k V）6～500The allowable working temperature cannot exceed90℃.

VV-Voltage level（k V）1～6The allowable working temperature cannot exceed65～70℃.

VVThe cable is insulated with polyvinyl chloride sheath and made of thermoplastic material.

YJVThe cable is a cross-linked polyvinyl chloride insulated polyvinyl chloride sheath, which is a thermosetting material.

It's precisely because of the different materials,soVVandYJVThe cable allows for long-term operation at different rated temperatures.

There are also differences between the two in terms of production equipment and manufacturing processes:

VVFor plastic cables,YJVCross linked cables have better insulation performance than plastic cables.

YJVJust crosslinked the insulation material to increase its heat resistance temperature,ButVVNo.
