TCVN type names (Vietnam): how to read the cable type names
Each name in TCVN type names (Vietnam) stands for a whole cable type: CVV, for example, comes with its own construction, standard and rating. The decoder knows 7 types of this system. Below: how the names are built, every type with its rating, and the sources the table names.
How a name is built
The type table does not split these names into parts: each name stands for the whole cable type.
Every type in TCVN type names (Vietnam)
| Type | Description | Rating |
|---|---|---|
VCm | VCm: single-core flexible (class 5) copper wire, PVC insulation, no sheath | 300/500 V (0.5 to 1 mm2), 450/750 V (1.5 to 240 mm2); 0.6/1 kV with V-75 PVC to AS/NZS 5000.1 (Cadivi) |
VCmd | VCmd: flat twin flexible cord, two PVC-insulated class 5 copper cores joined side by side, no sheath | 0.6/1 kV as printed by Cadivi, PVC 75 C (V-75); 0.5 to 2.5 mm2 |
VCmo | VCmo: flat (oval) two-core flexible cable, class 5 copper, PVC insulation and PVC sheath | 300/500 V; 0.75 to 6 mm2 (Cadivi) |
VCmt | VCmt: round multi-core flexible cable, class 5 copper cores twisted together, PVC insulation and PVC sheath | 300/500 V; 2 to 4 cores, 0.75 to 6 mm2 (Cadivi) |
CV | CV (Vietnam): single-core stranded (class 2) copper wire, PVC insulation, no sheath | 450/750 V (TCVN 6610-3), 0.6/1 kV with V-75 PVC (AS/NZS 5000.1), 600 V (JIS C 3307), as Cadivi prints them |
CVV | CVV: copper conductors, PVC insulation and PVC sheath | 300/500 V (2 to 4 cores, 1.5 to 35 mm2) or 0.6/1 kV, as Cadivi prints it |
CXV | CXV: copper conductors, XLPE insulation and PVC sheath, 0.6/1 kV power cable | 0.6/1 kV (TCVN 5935-1) or 600 V (JIS C 3605), as Cadivi prints it |
