Lamifil is a vertically integrated manufacturer of aluminium and aluminium alloy wire rod used for a wide range of electrical applications. The appropriate alloy will be selected or developed in order to optimize the balance between mechanical and electrical properties. We are making the full advantage of its metallurgic know-how available to transmission and distribution network owners.
- Fully annealed aluminium
The main advantage of fully annealed or soft aluminium is the higher conductivity. The maximum continuous operating temperature is limited by the type of conductor itself rather than by the aluminium. - Hard drawn aluminium
Hard drawn aluminium is typically used for ACSR conductors. It can be used up to 80°C. - Aluminium alloys
Aluminium Magnesium Silicon also called AMS or Aldrey is typically used for AAAC overhead conductors. It can be used up to 90°C.
Lamifil has developed AMS alloys with improved conductivity while keeping the same mechanical strength. This achievement allows us to offer mechanically equivalent AAAC conductors but with a higher conductivity resulting in significantly lower power losses.
Al 59 or AA1120 is also used for AAAC overhead conductors. Compared to the AMS alloys conductivity is quite high, but the strength has been significantly reduced. It can be used up to 90°C. - Lamifil aluminium zirconium alloys
By doping aluminium with zirconium the temperature at which the annealing process of the aluminium starts, is considerably increased. Therefore aluminium zirconium alloys can resist higher continuous temperatures. Several types of AlZr can be distinguished depending on the zirconium content and the manufacturing process: TAL, ZTAL, KTAL and XTAL.
