AL/XLPE/CWS/SWA/PE
AL/XLPE/CWS/SWA/PE is a Layer-list designation (CU/XLPE/SWA/PVC style, IEC and BS practice) cable designation: AL = Aluminium Conductor; XLPE = Cross-Linked Polyethylene (XLPE); CWS = Copper Wire Screen (concentric copper wires); SWA = Steel Wire Armour (round galvanised steel wires); PE = Polyethylene (PE).

Fire behaviour (EU CPR)
PE sheath (PE).
Typically targeted, as declared by makers for this kind of construction in the examples this site checked (not the class of this cable):
FcaYMeKrvaslqwd, TKFFcaNA2XS(F)2Y, Waskönig+Walter
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 →

AL/XLPE/CWS/SWA/PE as the cable designer builds it, 3x95/25 12/20 kV
Overall diameter 72.3 mm, about 6,740 kg/km. Nominal values from the standard's tables for this size, computed, not a maker's data.

| Insulation | XLPE | 5.5 | 23.7 |
| Insulation screen (semicon) | Semiconducting | 0.80 | 25.3 |
| Filler | Semiconducting | 54.5 | |
| Inner covering / bedding | Semiconducting | 0.60 | 55.7 |
| Wire screen | Copper | 65 × 0.70 | 57.3 |
| Sheath | PE | 1.7 | 60.7 |

AL/XLPE/CWS/SWA/PE on a drum
The smallest drum that passes every check, for 72.3 mm and about 6,740 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 | 4,545–4,610 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 = 1,446 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.
