Which type of wire conductor is most common in automotive electrical systems?

The most common type of wire conductor used in automotive electrical systems is stranded copper wire. Stranded wire is preferred because it is more flexible and resistant to fatigue compared to solid wire, making it suitable for the dynamic environment of vehicles. Additionally, copper's Excellent conductivity ensures efficient electrical performance. Automotive wiring is typically insulated with materials like PVC or cross-linked polyethylene to enhance durability and resistance to heat and chemicals.
