Abstract
A multi-core electrical cable for use in the supply of electricity to certain electrical devices such as vapor lamps and the like comprises a molded-on outer sheath and at least two separately insulated inner core cables. At least one of the core cables has a high tension conducting core with an overall cross-sectional area of at least 1 mm square. Preferably, the high tension conducting core comprises a bundle of at least 32 strands of 0.2 mm diameter tinned copper wire with an insulating sheath which is at least 1.8 mm thick. The molded-on outer sheath of the multi-core cable preferably totally encapsulates the inner cables to a depth of at least 1.3 mm.
