Medium voltage cable

What are the types of medium voltage cables?
The main types of medium voltage cables are YJV cable, VV cable, YJLV cable and VLV cable.
YJV cable full name XLPE insulated PVC sheathed power cable (copper core).
VV cable full name PVC insulated PVC sheathed power cable (copper core).
YJLV cable full name XLPE insulated PVC sheathed aluminum core power cable.
VLV cable full name PVC insulated PVC sheathed aluminum core power cable.
Because of the excellent electrical conductivity of copper conductor, more and more engineering uses copper core power cable as the main trunk of power supply system, but the application of aluminum core power cable is less, especially in the power system with high pressure, the more copper core cable is chosen.
