How to read a Norwegian type designation (NEK 606 offshore and Norwegian land cables) cable code
Fire behaviour (EU CPR)
Halogen-free compound (I). Under the CPR this shows in the additional classes: acidity a1 to a3 (EN 60754-2) and smoke s1 to s3 (EN 50399; s1a and s1b add the 3 m cube test EN 61034-2). The main class, Aca to Fca, depends on the whole construction.
Typically targeted, as declared by makers for this kind of construction in the examples this site checked (not the class of this cable):

Flame retardant (I). The single-cable test behind class Eca is EN 60332-1-2 (the flame stops within 425 mm). Bunched cables are tested by IEC 60332-3-24 category C (1.5 l/m, 20 min, char at most 2.5 m), which is not a CPR class test; the CPR ladder test for B1ca to Dca is EN 50399.
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 →

No equivalent in: BS 6622 (armoured cables only).
Nominal values computed by each standard's rules, not manufacturer data. This is not a statement that two cables are interchangeable: the buyer's specification and the maker's type test decide.
TSLI as the cable designer builds it, 1x240/25 12/20 kV
Overall diameter 39.8 mm, about 1,900 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 |
|---|---|---|---|
| Conductor screen (semicon) | Semiconducting | 0.60 | 19.6 |
| Insulation | XLPE | 5.5 | 30.6 |
| Insulation screen (semicon) | Semiconducting | 0.80 | 32.2 |
| Swelling tape (water block) | Swelling | 0.30 | 32.8 |
| Wire screen | Copper | 65 × 0.70 | 34.4 |
| Swelling tape (water block) | Swelling | 0.30 | 35.0 |

TSLI on a drum
The smallest drum that passes every check, for 39.8 mm and about 1,900 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 18 (1800 mm flange), wood KTG drums (Europe), Bayka, KTG | 7 of 8 | 1,291–1,363 kg |
| 1,000 m | KTG 22 (2200 to 2240 mm flange), wood KTG drums (Europe), Bayka, KTG | 7 of 8 | 2,460–2,653 kg |
Barrel at least 25 × OD = 995 mm for a cable of this kind (Medium voltage, single core): KTG table, the cable's datasheet wins. A load rating is the drum maker's own.

Laying, sizes and datasheet: TSLI
TSLI 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
