Automotive Wire

Automotive Wires – Foundation of Modern Mobility
Automotive wires are the backbone of vehicle electrical systems, enabling safe and efficient power delivery, signal transmission, and system integration. From EVs to traditional passenger cars, choosing the right wire ensures performance, reliability, and compliance with international safety standards. Depending on application, automotive wires can be classified into high-voltage cables, U.S./Japanese standards (SAE J1128 & JASO D611), and global benchmarks (ISO 6722).

High Voltage Wire – Powering EVs and Energy Systems
High voltage wire handles voltages above 600V and is essential for EVs, battery packs, industrial machinery, solar systems, and ESS. With silicone, XLPE, or ETFE insulation, these cables offer resistance to heat, oil, and abrasion while meeting UL 758 and ISO 6722. Proper selection by voltage class, temperature rating, conductor type, and insulation ensures long-lasting and safe operation in energy-intensive environments.

Global Automotive Standards – SAE J1128, JASO D611 & ISO 6722
SAE J1128 defines GPT, GXL, SXL, and TXL wires widely used in U.S. vehicles, focusing on abrasion resistance, chemical durability, and heat tolerance up to 125°C. JASO D611 sets requirements for AV, AVS, AVSS, and CAVUS wires used in Japanese and Asian vehicles, emphasizing lightweight and space-saving harnesses. ISO 6722 serves as the international benchmark, covering copper-based conductors, multiple insulation types (PVC, XLPE, TPE, ETFE), and temperature classes up to 150°C. It ensures consistent quality and reliability for global OEMs and harness manufacturers.
