J1VV-U

J1VV-U is a ELOT type names (Greece) cable designation: J = J: made to IEC ('Κατά IEC'), the Greek counterpart of the E name; 1 = 1: rated voltage 0,6/1 kV ('1 = 1 kV'), not the HD 361 100/100 V; V = PVC insulation; V = PVC sheath; -U = Round Solid Conductor (Class 1); J1VV-U = J1VV-U: PVC-insulated, PVC-sheathed 0,6/1 kV power cable (IEC name of NYY), round solid conductor (class 1). 0,6/1 kV. IEC 60502-1 (J) / ELOT (E); TEE Table 1.3.1.

Fire behaviour (EU CPR)

PVC sheath (V, J1VV-U).
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 →

J1VV-U: equivalents in other countries

Shown for 1x16 0.6/1 kV. 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
Germany	HD 603 3-G (DIN VDE 0276-603)	NYY 1x16 RE 0,6/1 kV	Close	Sheath 1.4 → 1.8 mm; Overall diameter 9.31 → 10.11 mm; this cable as built misses 2 of its rules
India	IS 1554 (Part 1)	no letters for this build	Close	rated 0.635/1.1 kV (same Um 1.2 kV); conductor RE → RM; Sheath 1.4 → 1.8 mm; Overall diameter 9.31 → 10.5 mm; this cable as built misses 1 of its rules

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.

J1VV-U as the cable designer builds it, 1x16 0.6/1 kV

Overall diameter 9.3 mm, about 220 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	6.5
Sheath	PVC	1.4	9.3

J1VV-U on a drum

The smallest drum that passes every check, for 9.3 mm and about 220 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 6 (600 mm flange), plywood KTG drums (Europe), Bayka	12 of 12	117 kg
1,000 m	KTG 8 (800 mm flange), wood KTG drums (Europe), Bayka, KTG	15 of 15	251–255 kg

Barrel at least 20 × OD = 186 mm for a cable of this kind (Low voltage, single core): KTG table, the cable's datasheet wins. A load rating is the drum maker's own.

Laying, sizes and datasheet: J1VV-U

J1VV-U belongs to the family LV PVC power 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 PVC power cables
