Invar Conductors

These conductors use a combination of Aluminium Clad Invar (a special Fe-Ni alloy with very low thermal expansion coefficient) for the core, and super thermal resistant Al-Zr alloy for the conductive layer. This allows:

• Low conductor thermal expansion coefficient that limits the sag increase with the increase of the temperature
• Have mechanical properties (diameter, strength, weight) very similar to ACSR conductors
• Maintaining the mechanical strength of the conductor with continuous operating temperature up to 210°C
• Easy installation, using the same installation method of standard ACSR conductors
• High corrosion resistance of the core thanks to the use of ACI

Invar conductors are especially suitable to replace ACSR conductors in short and middle spans lengths in all the orographic conditions (plain, hill or mountains).
