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 unscreened-core armoured 6.6 kV selection, not a generic promise of performance.<\/p>\n<p>The supplied construction uses three phase cores and one pilot core, all unscreened, laid up in contact with one another and protected by galvanized steel pliable armour between inner and outer sheaths. That arrangement matters because Type 621 is armoured and unscreened; it is therefore a different construction path from individually screened Type 630\/631 and Type 730. The family should therefore be selected by model, core function and installation route as well as by voltage.
