Introduction

Copper Conductor Concentric Cable Descripton:

voltage：0.6/1KV conductor: copper or aluminum alloy, insulation: PVC, sheath :PVC

1. application: The concentric cable 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 concentric 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.

2. Construction: soft annealed copper conductor, class 2 stranding, XLPE inner insulation, neutral conductor applied as an armoring of soft annealed copper wires and a XLPE outer insulation.

Identification of the Insulated Conductors:

The identification is made by the color of the insulation material, being:

•Single-phase conductor: black

•Two-phase conductors: black and red

•Three-phase conductors: black, red and white

Max conductor temperatures

90° at continuous service, 130° overloaded and 250° at short-circuit.
