CVT
CVT is a JIS type names (Japan) cable designation: C = C: cross-linked polyethylene (XLPE) insulation; V = V: PVC (vinyl) sheath; T = T: triplex, three single-core cables twisted together; CVT = CVT: triplex CV, three single-core XLPE / PVC cables twisted together. 600 V, 90 C (SFCC p.12); also 3300 V and 6600 V (SFCC p.16, p.20), 6/10 kV (Taihan). JIS C 3605 (600 V); JCS 4516 (3300 V); JIS C 3606 (6600 V); KS C IEC 60502-2 (Korea, 6/10 kV).

Fire behaviour (EU CPR)
PVC sheath (V, CVT).
Typically targeted, as declared by makers for this kind of construction in the examples this site checked (not the class of this cable):
EcaN1XV-R, Ahlsell (seller)Cca-s3,d1,a3FG16OR16, Nexans (La Triveneta Cavi)EcaU1000 R2V, Nexans (La Triveneta Cavi)EcaN2XSY, Waskönig+Walter (10 kV datasheet)
Listed as sources, alphabetically by maker. No maker pays to appear here.
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 →

CVT as the cable designer builds it, 1x16 0.6/1 kV
Overall diameter 9.1 mm, about 210 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 | XLPE | 0.70 | 6.3 |
| Sheath | PVC | 1.4 | 9.1 |
CVT on a drum
The smallest drum that passes every check, for 9.1 mm and about 210 kg/km as the cable designer builds it. Drums as their makers print them; lengths are estimates within a few per cent of the cable makers' own tables: whole layers, wound diameter 1.05 × OD, 50 mm freeboard under the flange rim.
| Length | Drum size (its makers) | Layers | Gross weight |
|---|---|---|---|
| 500 m | KTG 6 (600 mm flange), plywood KTG drums (Europe), Bayka | 11 of 13 | 112 kg |
| 1,000 m | KTG 8 (800 mm flange), wood KTG drums (Europe), Bayka, KTG | 15 of 15 | 241–245 kg |
Barrel at least 20 × OD = 182 mm for a cable of this kind (Low voltage, single core): KTG table, the cable's datasheet wins. A load rating is the drum maker's own.

Laying, sizes and datasheet: CVT
CVT belongs to the family LV XLPE power cables: the lowest laying temperature, bending radius, pulling, depth, drum handling and the test after laying, every rule with its sources. Laying and handling guide: LV XLPE power cables
