AI Technical Summary

Problems solved by technology

The cable structure is complex, the overall performance is low, and the manufacturing process is cumbersome
Inorganic heat-resistant wires and cables usually use inorganic mineral insulating materials such as mica, magnesium oxide, etc. as insulation and heat-resistant materials, and copper, stainless steel, etc. The performance of installation and laying is extremely poor, and it is not suitable for laying in narrow and complicated spaces
