What is the introduction of high voltage cable models?

I. What is the introduction of high-voltage cable models? High-voltage power cable from the conductor material, can be distinguished into two kinds, - a kind of copper core, - a kind of aluminum core. Common high-voltage cable models are as follows: YJY/YJLY :Copper core/aluminum core cross-linked polyethylene insulated polyethylene sheathed high-voltage power cable NH-YJY :Copper core cross-linked polyethylene insulated polyethylene sheathed fire-resistant high-voltage power cables ZR-YJY22/ZR-YJLY22 :Copper core/aluminum core cross-linked polyethylene insulated steel belt armored polyethylene sheathed flame retardant high-voltage power cable ZR-YJY32/ZR-YJLY22 :Copper core/aluminum core cross-linked polyethylene insulated steel belt armored polyethylene sheathed flame retardant high-voltage power cables YJY32/ZR-YJLY32 :Copper core/Aluminum core crosslinked polyethylene insulated steel wire armored polyethylene sheathed flame retardant high voltage power cable ZR-YJV42/ZR-YJLV42 :Copper core/Aluminum core crosslinked polyethylene insulated steel wire armored polyethylene sheathed flame retardant high voltage power cable ZR-YJY62/ZR-YJLY62 :Copper core/Aluminum core crosslinked polyethylene insulated steel ribbon armored polyethylene sheathed flame retardant high voltage power cable ZR-YJY62/ZR-YJLY62 :Copper core/ Aluminum core crosslinked polyethylene insulated steel ribbon armored polyethylene sheathed flame retardant high voltage power cable ZR-YJYS2/ZR-YJLYS2 :Copper core/Aluminum core cross-linked polyzene insulated flame retardant high voltage power cable with interlocking armored polyzene sheathing

-Two. Each letter has its own representative of the significance of: L: on behalf of the conductor material for the aluminum core, T on behalf of the copper conductor material, but generally abbreviated not written, such as YJV; Y: on behalf of the jacket or insulation material for polyethylene; YJ: on behalf of the jacket or insulation material for the crosslinking of polyethylene; NH: show the fire-resistant, that is, the type of cable to make the fire-resistant type; ZR: show the flame-retardant, flame-retardant class difference, respectively, A, B, C, D, R, ZA for class; 22/32/42/62/S2: show armored, respectively, steel belt armored, fine steel wire armored, ZA for class; 22/32/42/62/S2: show armored, respectively, steel belt armored, fine steel wire armored, ZA for class; 22/32/42/62/S2: show armored, respectively, steel belt armored, fine steel wire armored, ZA for class D, R, ZA for the grade; 22/32/42/62/S2 :show armored, respectively, steel tape armored, fine steel wire armored, thick steel wire armored, non-magnetic stainless steel tape armored, with interlocking armored.
