CNCV-W
CNCV-W is a KS / KEPCO type names (Korea) cable designation: CN = CN: concentric neutral, copper wires laid round the insulated core; C = C: cross-linked polyethylene (XLPE) insulation; V = V: PVC (vinyl) sheath; -W = -W: water-blocking tapes (semiconducting and non-conducting) under the sheath; CNCV-W = CNCV-W: 22.9 kV-y concentric neutral cable, XLPE insulated, PVC sheathed, water-blocking. 22.9 kV-y, multi-grounded distribution (Taihan p.24). KEPCO standard (Korea Electric Power Corporation).

PVC sheath (V).
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 →
