High-voltage cables are a type of power cable, referring to cables used for transmitting power between 1kV and 1000kV. They are commonly used in power transmission and distribution. The components of high-voltage cables, from inside to outside, include: conductor, insulation, inner sheath, filling material (armor), and outer insulation. Of course, armored high-voltage cables are mainly used for underground installations, capable of withstanding high ground pressure and preventing damage from external forces.
Medium-voltage cables mainly include YJV cables, VV cables, YJLV cables, and VLV cables:
YV Cable, full name Cross-linked Polyethylene Insulated Polyvinyl Chloride Sheathed Power Cable (Copper Core)
WV Cable, full name Polyvinyl Chloride Insulated and Sheathed Power Cable (Copper Core)
YLV Cross-linked Polyethylene Insulated Polyethylene Sheathed Aluminum Core Power Cable
VLV Cable - Full Name: Polyvinyl Chloride Insulated Polyvinyl Chloride Sheathed Aluminum Core Power Cable
