MYYM
MYYM is a Romanian type names (SR) cable designation: M = Mobile installations (M - instalatii mobile); Y = PVC insulation (y - izolatie PVC); Y = PVC sheath (y - manta din PVC); M = Medium duty mobile cable (U light, M medium, G heavy); MYYM = MYYM: flexible cord for mobile use, medium duty, fine-stranded (class 5) copper cores in PVC insulation under a PVC sheath, 300/500 V (= H05VV-F). 300/500 V, 70 C conductor, 150 C short circuit for at most 5 s (Energoplast). SR EN 50525-2-11 (H05VV-F).

Fire behaviour (EU CPR)
PVC sheath (Y, MYYM).
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 →

MYYM as the cable designer builds it, 3x1.5 300/500 V
Overall diameter 8.1 mm, about 110 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 | 0.70 | 2.9 |
| Filler | PVC | 6.3 | |
| Sheath | PVC | 0.90 | 8.1 |
MYYM on a drum
The smallest drum that passes every check, for 8.1 mm and about 110 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 5 (500 mm flange), plastic KTG drums (Europe), Bayka, KTG | 13 of 14 | 58–59 kg |
| 1,000 m | KTG 8 (800 mm flange), wood KTG drums (Europe), Bayka, KTG | 14 of 17 | 141–145 kg |
Barrel at least 12 × OD = 98 mm for a cable of this kind (Flexible cable (class 5 or 6 conductor)): KTG table, the cable's datasheet wins. A load rating is the drum maker's own.

Laying, sizes and datasheet: MYYM
MYYM belongs to the family Flexible cords: the lowest laying temperature, bending radius, pulling, depth, drum handling and the test after laying, every rule with its sources. Laying and handling guide: Flexible cords
