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 roadway-extension family at 3.3 kV, not a generic promise of performance.<\/p>\n<p>The supplied construction uses three power cores and one earth core laid around an elastomeric centre, with galvanized pliable wire armour and a heavy flame-retardant PCP jacket with blue stripe. That arrangement matters because Type 321 leaves the power cores unscreened; Type 331 adds composite copper\/nylon phase screens. Both include an earth core and armouring. The family should therefore be selected by model, core function and installation route as well as by voltage.
