The Lightweighting Challenge of Automotive Electrical Systems
In modern automotive manufacturing, wiring harnesses are often referred to as the "nervous system" of a vehicle, accounting for approximately 5% of its total weight. Copper conductors make up 70% of this weight. With the development of new energy vehicles and intelligent driving technologies, achieving lightweight wiring harnesses without sacrificing conductivity has become crucial for improving driving range and energy efficiency.
FISSOT is committed to breaking through the performance bottlenecks of traditional pure copper wiring harnesses through advanced alloy conductor technology, providing global automakers with lighter, stronger, and more reliable transmission solutions.
Recommended Products
For modern New Energy Vehicles (NEVs) and intelligent driving systems, choosing the right conductor is vital for balancing weight, strength, and thermal resistance. FISSOT recommends Copper Clad Steel (CCS) wire for high-stress areas like ABS brake lines and sensor cables due to its exceptional tensile strength and vibration resistance. For extreme thermal environments and high-current EV connectors, our Nickel Clad Copper (NCC) wire offers unparalleled anti-oxidation properties and stable conductivity, ensuring long-term reliability under IATF 16949 rigorous standards.
