More stringent requirements of emission levels and fuel economy of modern passenger cars require a reduction of the total weight of these vehicles.
In addition to lighter body parts of a car the weight reduction of the cable harness is further possibility to reach this target.
High tensile strength conductor material like copper-magnesium (CuMg) or copper bronze (CuSn) allow a reduction of single core cable cross section from 0,35mm² down to 0,13mm². I addition to the reduction of the cross sections of the wires lighter conductor materials are another way to reduce the total weight of the cable harness.
Especially for bigger cross sections starting at 2,50mm² the use of aluminum conductors instead of standard copper conductors is a good way of weight reduction.
Currently it is possible to gain a weight reduction of approx. 20% due to the reduction of the cross-sections of the conductor and the use of aluminum instead of copper.
As alternative for expensive and complicated waterproofed sealing applications, Prysmian Group provides T3 (125°C/3.000h) and T4 (150°C/3.000h) anti-capillary single core wires. The copper strands of the conductor are covered with a special material which prevents fluids penetrating the copper conductor. With this special conductor electronics and sensors on the ends of the cables are protected against damage.
