Aluminium
and aluminium alloys are progressively replacing copper in electric cables
and in particular in the case of flexible cable.
Travar proposes three specific alloys for these cables.
- Alloy 6101 Almelec
(AlMgSi) for underground telephone cables, for submarine cables and
for the screening of all types of cables.
- Alloy 1110 Aluflex
(AlFeMg) for making cables and strands for the car, aeronautical and
railroad industries, and other types of power cables.
- High conductivity
Aluminium 1370, used in high-current power cables.
These alloys
can be supplied in: 6,7,8 and even 16 strand wires.
The tables supply the characteristics of alloys 6101, 1110 ad a comparison
with copper.
