The
lightness:Aluminium and aluminium alloys are appreciated for their lightness
compared with many other metals such as Copper.
- Good conductivity
(2/3 higher than Copper).
- Resistance to corrosiuon.
Thanks to the importance
of these characteristics, the Aluminium Alloy, is paramount in underground,
underwater telephone cables and in shielding of cables in general.
The project was born as a consequence of continuous expand of conductor's
market and from here the idea to apply a research turned to technological
innovation. The chart below gives an exact comparison between the characteristics
of some alloy and copper. With such important project TRAVAR will be
able to offer multi-wire even with different aluminium alloys.
