XHIOV
XHIOV is a NP 665 (Portugal) cable designation: X = Cross-linked polyethylene (XLPE) insulation; HIO = HIO: radial-field cable, a copper wire screen over each core; V = PVC sheath; XHIOV = XHIOV: medium-voltage cable, copper conductor, XLPE insulation, radial field with a copper wire screen on each core, PVC sheath (HD 620 type 10L-1). 6/10 (12) to 18/30 (36) kV; 90 C conductor, 120 C short duration overload, 250 C short circuit (5 s) (HD 620 S3 10-L 1). HD 620 S3:2023 section 10-L, No. 14 code designation (p. 10-L-11), Type 10L-1; XLPE DIX 13 (1, p. 10-L-3). Owner's copy, read 2026-10-31, seen: standard; NP 665 letters.

Fire behaviour (EU CPR)
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 →
