This page keeps the source-listed voltage, test reference, core functions and dimensional tables together so a procurement engineer can compare the requested model against the cable marking and the equipment connection. The editorial focus is the armoured unscreened power path, not a generic promise of performance.<\/p>\n<p>The supplied construction uses three or four unscreened cores laid around an elastomeric cradle without contacting one another, with galvanized steel pliable armour between inner and outer sheaths. That arrangement matters because The core count is the principal distinction: Type 20 is three-core and Type 21 is four-core; neither is an individually screened coal-cutter cable. The family should therefore be selected by model, core function and installation route as well as by voltage.
