Fire behaviour (EU CPR)
Flame retardant (TFR-, TFR-CV). 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.
PVC sheath (TFR-, V, TFR-CV).
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 →

TFR-CV: 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 5-G (DIN VDE 0276-603) | N2XY 1x16 RM 0,6/1 kV | Close | Sheath 1.4 → 1.8 mm; Overall diameter 9.1 → 9.9 mm |
| India | IS 7098 (Part 1) | 2XY 1x16 1100 V | Close | rated 0.635/1.1 kV (same Um 1.2 kV); Sheath 1.4 → 1.8 mm; Overall diameter 9.1 → 9.9 mm; this cable as built misses 1 of its rules |
No equivalent in: BS 5467 (not in its cable tables, armoured cables only); BS 6724 (not in its cable tables, armoured cables only, asks another sheath compound); BS 7846 (not in its cable tables, armoured cables only, asks another sheath compound).
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.
TFR-CV as the cable designer builds it, 1x16 0.6/1 kV
Overall diameter 9.1 mm, about 210 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 | XLPE | 0.70 | 6.3 |
| Sheath | PVC | 1.4 | 9.1 |
TFR-CV on a drum
The smallest drum that passes every check, for 9.1 mm and about 210 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 | 11 of 13 | 112 kg |
| 1,000 m | KTG 8 (800 mm flange), wood KTG drums (Europe), Bayka, KTG | 15 of 15 | 241–245 kg |
Barrel at least 20 × OD = 182 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: TFR-CV
TFR-CV belongs to the family LV XLPE 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 XLPE power cables
