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):
- Eca N1XV-R, Ahlsell (seller)
- Cca-s3,d1,a3 FG16OR16, Nexans (La Triveneta Cavi)
- Eca U1000 R2V, Nexans (La Triveneta Cavi)
- Eca N2XSY, 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 →

AYFY as the cable designer builds it, 3x16 1100 V

Overall diameter 19.9 mm, about 690 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

AYFY on a drum

The smallest drum that passes every check, for 19.9 mm and about 690 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	416–423 kg
1,000 m	KTG 12 (1250 mm flange), wood KTG drums (Europe), Bayka, KTG	12 of 12	834–855 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.
