Robust cables for long distance power transfer
July 2014
Enclosures, Cabling & Connectors
Aberdare Cables’ Armadac provides a cost effective means of transferring power over long distances through intermediate voltage step-up step-down systems. Armadac consists of three circular stranded plain soft copper conductors, PVC insulated, PVC bedded, SteelWire armoured and PVC sheathed. It is suitable for 1,9/3,3 kV operation and is manufactured to SANS 1507-3.
The advantage of using an intermediate voltage cable over the conventional 400 V 3-phase system is that the voltage drop, expressed as a percentage, will be considerably lower allowing smaller conductor sizes to suffice for most applications. The Armadac cable is steel wire armoured and provides a robust mechanical protection to the cable, making it suitable for underground installation.
Armadac’s steel wire armouring offers additional protection against attack by rodents and other animals and the armouring can also be utilised as an earth path, eliminating the need for an external earth conductor. Armadac makes use of circular cores which limits electrical stress in the insulation and also incorporates a flame retardant PVC sheath, to limit the spread of fire.
Suitable for use in a -10 to 70°C temperature range, Armadac is supplied in 500 m wooden drums and is identified by red, yellow and blue cores.
