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 possible to reach this target.
High tensile strength conductor material like copper-magnesium (CuMg) or copper bronze (CuSn) allows 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 an 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 that prevents fluids from penetrating the copper conductor. With this special conductor electronics and sensors on the ends of the cables are protected against damage.
