What is VTLB cable?
VTLB: Belgian name of the light flexible PVC cord H03VV-F, 300/300 V: fine-stranded copper cores in PVC insulation under a PVC sheath. Rating: 300/300 V. Standard: HD 21.5 / NBN C 32-123 (H03VV-F, now EN 50525-2-11).
Rexel Belgium sheet "VTLB VTLBp VTLmB VTMB" (c. 2007): VTLB, VTLBp, VTLmB (300 V) = H03VV-F. NBN installation key (Cebeo Tome 04 2011 p. 24): T cord, L light insulation (printed there as 300/500 V; the H03VV-F cord is 300/300 V).

A CPR class is declared by the maker in its Declaration of Performance and printed on the sheath (EN 50575 cl 7). This decoder does not assign one. What the CPR classes mean →

VTLB: equivalents in other countries
Shown for 2x0.75 300/300 V. Each country's rules are applied to this build, keeping the conductor, section, cores, voltage, screen, armour and sheath.
| Country | Standard | Name in that country | Verdict | Differences |
|---|---|---|---|---|
| Europe | EN 50525-2-12 | H03VVH8-F 2x0,75 300/300 V | Equivalent | every value the same |
| Europe | EN 50525-2-51 | H05VV5-F 2x0,75 300/500 V | Close | rated higher: 300/500 V (this cable 300/300 V); Insulation 0.5 → 0.6 mm; Sheath 0.6 → 0.8 mm; Overall diameter 5.41 → 6.21 mm |
| India | IS 694 | FR FLEXIBLE 2x0,75 1100 V | Close | rated higher: 1100 V (this cable 300/300 V); Insulation 0.5 → 0.6 mm; Sheath 0.6 → 0.9 mm; Overall diameter 5.41 → 6.41 mm |
| China | GB/T 9330 | KVVR 2x0.75 450/750 V | Close | rated higher: 450/750 V (this cable 300/300 V); Insulation 0.5 → 0.6 mm; Sheath 0.6 → 1.2 mm; Overall diameter 5.41 → 7.01 mm |
Nominal values computed by each standard's rules, not manufacturer data. This is not a statement that two cables are interchangeable: the buyer's specification and the maker's type test decide.
VTLB as the cable designer builds it, 2x0.75 300/300 V
Overall diameter 5.4 mm, about 40 kg/km. Nominal values from the standard's tables for this size, computed, not a maker's data.
| Layer | Material | Thickness, mm | Over the layer, mm |
|---|---|---|---|
| Insulation | PVC | 0.50 | 2.1 |
| Filler | PVC | 4.2 | |
| Sheath | PVC | 0.60 | 5.4 |
VTLB on a drum
The smallest drum that passes every check, for 5.4 mm and about 40 kg/km as the cable designer builds it. Drums as their makers print them; lengths are estimates: whole layers wound nested (each turn in the groove of the layer below), wound diameter 1.05 × OD, 50 mm freeboard under the flange rim. Cable makers' own tables print less, as they count aligned layers.
| Length | Drum size (its makers) | Layers | Gross weight |
|---|---|---|---|
| 500 m | KTG 3 (390 mm flange), plastic KTG drums (Europe), KTG | 12 of 16 | 22 kg |
| 1,000 m | KTG 4 (435 mm flange), plastic KTG drums (Europe), KTG | 20 of 21 | 42 kg |
Barrel at least 12 × OD = 65 mm for a cable of this kind (Flexible cable (class 5 or 6 conductor)): KTG table, the cable's datasheet wins. A load rating is the drum maker's own.
