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

IS 1554-2 as the cable designer builds it, 3x185 6.35/11 kV
Overall diameter 72.6 mm, about 12,300 kg/km. Nominal values from the standard's tables for this size, computed, not a maker's data.

| Insulation | PVC | 4.2 | 25.7 |
| Insulation screen (semicon) | Semiconducting | 0.80 | 27.3 |
| Tape screen | Copper | 0.20 | 27.7 |
| Filler | PP | 59.6 | |
| Inner covering / bedding | PVC | 0.70 | 61.0 |

IS 1554-2 on a drum
The smallest drum that passes every check, for 72.6 mm and about 12,300 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, 76 mm freeboard under the flange rim.
| Length | Drum size (its makers) | Layers | Gross weight |
|---|---|---|---|
| 500 m | KTG 28 (2800 mm flange), wood KTG drums (Europe), Bayka, KTG | 5 of 5 | 7,325–7,390 kg |
| 1,000 m | No single drum in KTG drums (Europe) takes it: the drum calculator splits it over several. | ||
Barrel at least 20 × OD = 1,453 mm for a cable of this kind (Medium voltage, multi-core): KTG table, the cable's datasheet wins. A load rating is the drum maker's own.

Laying, sizes and datasheet: IS 1554-2
IS 1554-2 belongs to the family Medium voltage 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: Medium voltage cables
