Abstract
An electrical power cable includes a conductor core having at least two insulated phase conductors twisted together and a binder tape configured to cover the twisted conductor core. A bare aluminum grounding conductor is laid longitudinally outside the binder tape, along the length of the conductor core and a metal armor is disposed around the grounding conductor and conductor core defining a metal armor for the electrical power cable.
