Fire behaviour (EU CPR)
PVC sheath (Y).
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 →

YFY as the cable designer builds it, 3x16 1100 V
Overall diameter 19.9 mm, about 1,000 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 | 1.0 | 6.9 |
| Filler | PP | 14.9 | |
| Inner covering / bedding | PVC | 0.30 | 15.5 |
| Wire armour | Steel | 12 × 0.80 | 17.1 |
| Sheath | PVC | 1.4 | 19.9 |
YFY on a drum
The smallest drum that passes every check, for 19.9 mm and about 1,000 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 10 (1000 mm flange), wood KTG drums (Europe), Bayka, KTG | 9 of 9 | 571–578 kg |
| 1,000 m | KTG 12 (1250 mm flange), wood KTG drums (Europe), Bayka, KTG | 12 of 12 | 1,144–1,165 kg |
Barrel at least 15 × OD = 298 mm for a cable of this kind (Low voltage, multi-core): KTG table, the cable's datasheet wins. A load rating is the drum maker's own.
