Aluminum wires for all power segments Key factor for reducing the
harnesses’ weight is the substitution of conventional copper wires. Besides
copper wires with reduced cross-sections, Leoni mainly offers wires made of
aluminum for all three power segments, i.e. with cross- section smaller than 2.5
mm2, up to 10mm2 and bigger. In spite of the fact that aluminum conductors have
a higher cross-section in order to ensure the same electrical conductivity, the
aIuminum technology allows a weight reduction of approximately 50 per cent
compared to copper wires. The utilisation of aluminum products, wherever
reasonable, will slim the wiring system’s weight by about 10 per cent.
