<p>A multi-core electrical cable (13) for use in the supply of electricity to certain electrical devices such as vapour lamps and the like comprises a moulded-on outer sheath (14) and at least two separately insulated inner core cables (9, 10, 11). At least one of the core cables (9, 10) has a high tension conducting core (3) with an overall cross-sectional area of at least 1 mm2. Preferably, the high tension conducting core (3) comprises a bundle of at least 32 strands of 0.2 mm diameter tinned copper wire (4) with an insulating sheath (2) which is at least 1.8 mm thick. The moulded-on outer sheath (14) of the multi-core cable (13) preferably totally encapsulates the inner core cables (9, 10, 11) to a depth of at least 1.3 mm.</p> |
