TXSE
TXSE is a Norsk typebetegnelse (Norway) cable designation: T = 1st letter, insulation: cross-linked polyethylene, PEX ('Tverrbundet polyetylen'); HD 620 10-K Table 4: XLPE insulation; X = 2nd letter: no sheath or similar ('Ingen kappe e.l.'); not explained in HD 620 10-K Table 4; S = 3rd letter: concentric conductor ('Konsentrisk leder'); HD 620 10-K Table 4: copper screen; E = 4th letter, outer sheath: PE (HD 620 10-K Table 4: PE sheath); TXSE = TXSE: single-core medium-voltage cable, XLPE insulation, copper wire screen, PE sheath (an A after the section: aluminium conductor). 12 kV (Um) in the Table 4 example; HD 620 10-K covers Um 12, 24 and 36 kV. HD 620 S3:2023 Part 10 Section K, Table 4 'Code designation (provisional)', p. 10-K-22 (owner's copy): T XLPE insulation, S copper screen, P PVC sheath, E PE sheath, L aluminium sheath, I halogen-free flame retardant sheath, A after the section aluminium conductor (no letter: copper); letter positions as tabled in the Nexans Kabelboka.

FcaYMeKrvaslqwd, TKFFcaNA2XS(F)2Y, Waskönig+Walter
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 →

No equivalent in: BS 6622 (armoured cables only).
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.
