Wire and cable specifications and models are primarily distinguished by their identification codes, which include various aspects such as application, conductor material, insulation material, inner sheath, and outer sheath.
I. Wire and Cable Application (Category) Identification
A indicates installation wire, B indicates wiring, C indicates marine cable, H indicates welding cable, K indicates control cable, N indicates agricultural cable, U indicates mining cable, Y indicates mobile cable, and JK indicates overhead insulated cable.
II. Conductor Material Identification
L indicates aluminum conductor, T indicates copper conductor.
III. Insulation Material Identification
V indicates polyvinyl chloride insulation, X indicates rubber insulation, Y indicates polyethylene insulation, YJ indicates cross-linked polyethylene insulation, and Z indicates oil-impregnated paper insulation.
IV. Sheath Material Identification
V indicates polyvinyl chloride sheath, Y indicates polyethylene sheath, L indicates aluminum sheath, Q indicates lead sheath, H indicates rubber sheath, and F indicates neoprene sheath.
5. Characteristic Identification
D indicates non-drip cable, F indicates split-phase cable, CY indicates oil-filled cable, P indicates oil-poor dry-insulated cable, P indicates shielded cable, Z indicates DC cable, B indicates flat cable, R indicates flexible cable, C indicates heavy-duty cable, Q indicates light-duty cable, G indicates high-voltage cable, and S indicates twisted-pair cable.
6. Armored Control Layer Identification
0 indicates none, 2 indicates double steel tape, 3 indicates fine steel wire, and 4 indicates coarse steel wire.
7. Fire Resistant Characteristic Identification
ZR preceding the code indicates flame-retardant cable, ZABC indicates the flame retardant grade; NH preceding the code indicates fire-resistant cable, DH preceding the code indicates fire-resistant cable, and WD indicates low-smoke, halogen-free cable. Therefore, in our daily work, we often see models marked with "ZR"
Common wire and cable model examples and their meanings:
VV: PVC insulated and PVC sheathed copper core cable.
YJV: XLPE insulated and PVC sheathed copper core cable.
NH-YJV: Fire-resistant XLPE insulated and PVC sheathed copper core cable.
ZR-YJLV: Flame-retardant XLPE insulated and PVC sheathed aluminum core cable.
WDZ-YJV22: Low-smoke, halogen-free XLPE insulated and PVC sheathed armored copper core cable.
