What is AHXCMK-WTC cable?
AHXCMK-WTC: three-core medium-voltage cable, aluminium conductors, XLPE, common copper wire screen, PE (10F-13) or PVC (10F-14) oversheath. 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 A27 (p. 10-F-54) (provisional type designation); XLPE DIX 14, sheath PVC DMV 10 or PE DMP 15 (1, p. 10-F-3). seen: standard.
Types 10F-13 (PE oversheath) and 10F-14 (PVC oversheath): the cores laid up under one copper wire screen (Table A25: 16 to 35 mm²) and one oversheath (Table A26). Drawn with the PE oversheath of 10F-13. 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.
