high-temperaturecorrosion-resistantmulti-strand

This is the most common solution for repowering the existing lines. These conductors use a special steel alloy Fe-Ni (Invar) which main characteristic is the very low thermal expansion coefficient. Invar is covered by a thin layer of aluminium extruded on it which prevent the corrosion and the wire is identified by the acronym ACI (Aluminium Clad Invar). The conductive external layers are made of a super thermal resistant Al-Zr alloy which operating temperature can reach the 210°C. The main point of this product family are: Low coefficient of thermal expansion which limit the increasing of temperature with high temperature Mechanical properties very similar to ACSR Easy installation, using the same installation method of standard ACSR conductors High corrosion resistance of core thanks to the use of ACI They are suitable to replace ACSR in all the orographic conditions
