What is HXAMK-W cable?
HXAMK-W: three copper cores (XLPE, aluminium laminated foil screen, PE sheath) laid up round a bare copper earth conductor, watertight (HD 620 type 10F-3). 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 A12 (p. 10-F-45) (provisional type designation); XLPE DIX 14, sheath PVC DMV 10 or PE DMP 15 (1, p. 10-F-3). seen: standard.
Type 10F-3: the copper twin of AHXAMK-W; earth conductor bare stranded compacted copper, at least 35 mm² (No. 1.9). Before 2026-10-31 HXAMK-W read as Old VDE 0250 letters. 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.
