NYY-G

NYY-G is a TIS 11 type names (Thailand) cable designation: NYY-G = NYY-G: Thai NYY (PVC insulation, PVC inner and outer sheath) with a green-and-yellow protective earth core; NYY-G = NYY-G (Thailand): PVC-insulated copper cores, PVC inner and outer sheath, with a green-and-yellow earth core. 300/500 V (60227 IEC 10) or 450/750 V (Part 101), 70 C (Thai Cable Wires). TIS 11 Part 4-2553 (60227 IEC 10, to 35 mm2, 300/500 V) and TIS 11 Part 101-2553 (NYY-G, 450/750 V).

Fire behaviour (EU CPR)

PVC sheath (NYY-G).
Typically targeted, as declared by makers for this kind of construction in the examples this site checked (not the class of this cable):
- Eca N1XV-R, Ahlsell (seller)
- Cca-s3,d1,a3 FG16OR16, Nexans (La Triveneta Cavi)
- Eca U1000 R2V, Nexans (La Triveneta Cavi)
- Eca N2XSY, 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 →

NYY-G as the cable designer builds it, 4x16 0.6/1 kV

Overall diameter 25.5 mm, about 1,270 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	1.0	6.9
Filler	PP		16.7
Inner covering / bedding	PVC	1.0	18.7
Sheath	PVC	1.2	21.1

NYY-G on a drum

The smallest drum that passes every check, for 25.5 mm and about 1,270 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 12 (1250 mm flange), wood KTG drums (Europe), Bayka, KTG	8 of 9	779–800 kg
1,000 m	KTG 16 (1600 mm flange), wood KTG drums (Europe), Bayka, KTG	10 of 13	1,546–1,579 kg

Barrel at least 15 × OD = 382 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.

Laying, sizes and datasheet: NYY-G

NYY-G belongs to the family LV armoured 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: LV armoured cables
