AI Technical Summary
Existing coil manufacturing methods suffer from limited conductivity, insufficient insulation, poor material compatibility, and unstable processes, resulting in low equipment operating efficiency, poor reliability, and short service life.
Highly conductive carbon nanotubes are combined with high-purity aluminum foil powder, and modified γ-alumina is introduced. This is combined with a ceramic-based composite insulating underlayer and a silicone rubber self-adhesive composite insulating coating. Through the synergistic effect of modified γ-alumina and other raw materials, the conductivity and insulation properties are improved. The process stability is ensured by precise winding and segmented curing processes.
It significantly improves the conductivity and insulation performance of the coil, reduces power loss, enhances the high temperature resistance and mechanical stability of the coil, ensures process stability and yield, and meets the requirements for stable operation in high temperature environments.
