Lamifil has developed a range of alloys that help reduce losses and CO2 emissions.
The All Aluminium Alloy Conductors with Ultra High Conductivity or AAAC UHC is probably the most efficient overhead conductor available today. It lowers CO2 emissions by reducing the need for generation capacity to compensate for network losses.
Keeping losses under control becomes even more important when you start using overhead conductors at higher temperatures. Our G(Z)TACSR conductor is manufactured using the best aluminium zirconium. For our ACCC® conductor we use fully annealed aluminium of the highest quality..
One of the tools to optimize conductor designs is the replacement of round wires by trapezoidal or z-shaped wires. Depending on the objective several options can be chosen:
- Same weight, smaller overall diameter, same capacity: lower ice and wind loading, less forces on towers, lighter structures, less environmental impact. Overall diameter reduced by up to 10%.
- Same overall diameter, higher section, increased capacity: aluminium section can be increased by up to 20%.
- Anything in between, with a specific strength to conductivity ratio of the alloy for optimised efficiency.
Using trapezoidal or z-shaped wires can offer many other advantages
- increase transport capacity
- reduction of drag coefficient
- internal corrosion protection and migration of grease
- reduced adherence of snow or ice
- less audible noise
Lamifil has been manufacturing overhead conductor with a with our DayOne® surface since 2003. The benefits are a higher emissivity factor and a hydrophilic surface.
Where very specific design criteria or specific needs have to be dealt with, we can rely on our broad knowledge of designing and manufacturing conductors. This ability together with the complete control of the production process from molten metal to finished conductor makes Lamifil your ideal partner for tailor-made designs.
