What is AHXCMKM-WTL cable?
AHXCMKM-WTL: three aluminium cores, each with XLPE, a copper wire screen and its own sheath, laid up under a common oversheath, watertight (HD 620 types 10F-11, 10F-12). Rating: 6/10 (12), 12/20 (24) and 18/30 (36) kV; 90 C conductor, 250 C short circuit (5 s) (HD 620 S3 10-F 1). Standard: HD 620 S3:2023 section 10-F, Table A23 (p. 10-F-52) (provisional type designation); XLPE DIX 14, sheath PVC DMV 10 or PE DMP 15 (1, p. 10-F-3). seen: standard.
Table A23: inner sheath PVC (10F-11) or PE (10F-12), oversheath the same; drawn as 10F-11. The first M is the sheath of each core, the last the common oversheath. HD 620 S3 10-F prints the name in a row with its conductor, metal screen and sheath; it does not spell out the letters, so the split follows the Finnish key (fi.wikipedia, secondary) and the table columns.
