The main types of high-voltage cables include YJV cables, VV cables, YJLV cables, and VLV cables.
YJV cables stand for cross-linked polyethylene insulated and PVC sheathed power cables (copper core).
VV cables stand for polyvinyl chloride insulated and PVC sheathed power cables (copper core).
YJLV cables stand for cross-linked polyethylene insulated and PVC sheathed aluminum core power cables.
VLV cables stand for polyvinyl chloride insulated and PVC sheathed aluminum core power cables.
Due to the excellent conductivity of copper conductors, copper core power cables are increasingly being used as the main power supply system in high-voltage cable projects. Aluminum core power cables are less commonly used, especially in higher-voltage cable systems, where copper core cables are increasingly preferred.
