Frequently Asked Questions

What are the main new energy applications for bimetallic conductors?

Bimetallic conductors are primarily used in electric vehicles (wiring harnesses, battery connections), solar PV systems (DC wiring, junction boxes), wind turbines (grounding, control cables), and energy storage systems (battery interconnects).

Why are bimetallic conductors preferred for EV applications?

Bimetallic conductors like CCA offer 40-50% weight reduction compared to copper, which directly translates to extended driving range for EVs. They also provide 30-40% cost savings while maintaining adequate electrical performance.

What standards apply to bimetallic conductors in new energy applications?

Key standards include IEC 62602 for CCA specifications, UL 758 for appliance wiring materials, and various automotive standards like IATF 16949 for quality management in automotive applications.
