Application of aluminum concentric cable
The concentric cables are used in service entrances replacing low voltage bundled copper cables in order to avoid energy robbery. A common way of energy robbery nowadays is using metallic claws, biting the phase and the neutral conductors, allowing the use of electricity without passing through the energy meter. However, the anti-robbery cable is so constructed that the use of the claws is not possible anymore. Its neutral conductor surrounding the phase like a wire armoring does not allow any contact with the central phase conductor without touching this concentric neutral conductor.
Construction of aluminum concentric cable
soft annealed aluminum conductor, class 2 stranding, XLPE inner insulation, neutral conductor applied as an armoring of soft annealed aluminum wires and a PE outer insulation.
