All Aluminium Alloy Conductor – Super High Conductivity (AAAC-SHC)
calendar_today Monday 05 June 2017
Reduced line losses, easy installation and replacement, less CO2 production: all this is AAAC-SHC.
“Conductivity at its best”
Aluminium alloy is already used by long time as material for overhead lines but the current technologies allow an improvement of conductivity.
The improvement of electrical conductivity of aluminium alloys is one of the main possible developments to obtain efficient, light and corrosion resistant conductors for low line losses.
Nowadays, AAAC SHC are on the edge of technology for overhead lines in terms of energy efficiency.
An accurate study of aluminium alloys properties and micro-structures has permitted to develop a material with a higher electrical conductivity compared to the traditional aluminium alloy used for conductors (AAAC), maintaining the same tensile strength.

The enhanced electrical conductivity allows an energy losses reduction more than 7%.
Furthermore, De Angeli Prodotti and TCH De Angeli innovative production process gives the possibility to obtain extremely high conductivity for different requirements of tensile strength, in order to satisfy all the costumer’s requirement.
The line losses are reduced: more conductive aluminium alloy reduces line losses up to 7% compared to conventional AAAC conductors of the same size and weight;
Easy installation or substitution: AAAC SHC conductors have the same section as the traditional one, so the substitution of the old lines can be performed without any problem. The new conductor can be installed exactly in the same way;
Less power generation and reduced CO2 emission: lower line losses means less power generation and less CO2 emissions to serve the same load.
New aluminium alloy conductors developed by De Angeli Prodotti and TCH De Angeli give very important advantages compared to the traditional one, the installation of this new product assures an important decrease in energy losses.
