What is NYM cable?
NYM: PVC installation cable (Mantelleitung) for fixed installation, the type of DIN VDE 0250-204. Rating: U0/U 300/500 V (clause 4); laying after DIN VDE 0298-3 (clause 7). Standard: DIN VDE 0250-204:2000-12 (1 core 1,5 to 16 mm², 2 to 5 cores 1,5 to 35 mm², 7 cores 1,5 and 2,5 mm², 5.1; bare copper, solid class 1 to 10 mm², stranded class 2 from 16 mm², 5.2; mean overall diameter limits, Table 1 columns 7 and 8, e.g. 3 x 1,5 mm²: 8,2 to 9,9 mm, 5 x 2,5 mm²: 11,0 to 13,3 mm; tests, Table 2: 2 kV a.c. for 5 min on the complete cable).
NYM-J has a green-and-yellow core, NYM-O none (3.2). The letter reading below this row is the DIN VDE 0250 letter code; this row is the type as the standard defines it.

PVC sheath (M).
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 →

NYM-J 3x1,5: equivalents in other countries
Shown for 3x1.5 300/500 V. Each country's rules are applied to this build, keeping the conductor, section, cores, voltage, screen, armour and sheath.
| Country | Standard | Name in that country | Verdict | Differences |
|---|---|---|---|---|
| International (IEC) | 60227 IEC 10 (IEC 60227-4) | 60227 IEC 10 3G1,5 300/500 V | Close | Insulation 0.6 → 0.7 mm; Sheath 1.4 → 1.2 mm |
| China | GB/T 9330 | KVV 3x1.5 450/750 V | Close | rated higher: 450/750 V (this cable 300/500 V); Insulation 0.6 → 0.7 mm; Inner covering / bedding material: not in the equivalent; Sheath 1.4 → 1.2 mm |
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.
NYM-J 3x1,5 as the cable designer builds it, 3x1.5 300/500 V
Overall diameter 9.2 mm, about 130 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 | 0.60 | 2.6 |
| Filler | PVC | 5.6 | |
| Inner covering / bedding | PVC | 0.40 | 6.4 |
| Sheath | PVC | 1.4 | 9.2 |
NYM-J 3x1,5 on a drum
The smallest drum that passes every check, for 9.2 mm and about 130 kg/km as the cable designer builds it. Drums as their makers print them; lengths are estimates: whole layers wound nested (each turn in the groove of the layer below), wound diameter 1.05 × OD, 50 mm freeboard under the flange rim. Cable makers' own tables print less, as they count aligned layers.
| Length | Drum size (its makers) | Layers | Gross weight |
|---|---|---|---|
| 500 m | KTG 6 (600 mm flange), plywood KTG drums (Europe), Bayka | 12 of 14 | 72 kg |
| 1,000 m | KTG 8 (800 mm flange), wood KTG drums (Europe), Bayka, KTG | 15 of 17 | 161–165 kg |
Barrel at least 15 × OD = 137 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.
