PVC sheath (Y, 6242Y).
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 →

6242Y as the cable designer builds it, 2x2.5+1.5 300/500 V

Flat, 10.2 × 5.4 mm (width × thickness), about 120 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	0.80	3.4
Filler	PVC		3.4
Sheath	PVC	1.0	5.4

6242Y on a drum

The smallest drum that passes every check, for 10.2 mm and about 120 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 7 (710 mm flange), wood KTG drums (Europe), Bayka, KTG	10 of 11	85–88 kg
1,000 m	KTG 9 (900 mm flange), wood KTG drums (Europe), Bayka, KTG	11 of 16	167–171 kg

Barrel at least 15 × OD = 152 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.
