Prysmian produces high-temperature conductors for upgrading existing lines. They are especially designed to solve problems relating to the construction of new lines due to lack of available lands, difficulties in getting permissions and environmental restrictions.

The high-temperature conductors allow an upgrade of the existing line, increasing the ampacity from to 1.5 to 2 times by replacing only the conductors. This guarantees a more convenient solution in terms of total cost of ownership.

The 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.
