TFR-CVVS
TFR-CVVS is a KS / KEPCO type names (Korea) cable designation: TFR- = TFR-: tray flame retardant, a high flame-retardant PVC sheath for cable trays; C = C: control cable (first letter of the control cable names CVV, CCV, CCE, HFCCO); V = V: PVC insulation; V = V: PVC (vinyl) sheath; S = S: copper tape shield over the laid-up cores; TFR-CVVS = TFR-CVVS: CVVS with a tray flame-retardant PVC sheath. 0.6/1 kV (Taihan p.36). KS C IEC 60502-1.

Fire behaviour (EU CPR)
Flame retardant (TFR-, TFR-CVVS). 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-CVVS).
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-CVVS as the cable designer builds it, 4x1.5 0.6/1 kV
Overall diameter 13.2 mm, about 250 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 | 0.80 | 3.0 |
| Filler | PP | 7.2 | |
| Inner covering / bedding | PVC | 1.0 | 9.2 |
| Tape screen | Copper | 0.20 | 9.6 |
| Sheath | PVC | 1.8 | 13.2 |
TFR-CVVS on a drum
The smallest drum that passes every check, for 13.2 mm and about 250 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 9 (900 mm flange), wood KTG drums (Europe), Bayka, KTG | 8 of 12 | 172–176 kg |
| 1,000 m | KTG 10 (1000 mm flange), wood KTG drums (Europe), Bayka, KTG | 12 of 14 | 321–328 kg |
Barrel at least 15 × OD = 198 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.
