Intelligent maintenance: Distributed fiber optic sensing (DTS/DAS) becomes standard equipment for high-voltage cables
Customized manufacturing: 3D printing promotes "on-demand production" of cable accessories
⚠️ Risk warning:
Energy consumption of liquid nitrogen cooling for superconducting cables is still high (≥0.3kWh/km·h)
Lead-free materials have caused the cost of PVC cables to increase by more than 25%
These cases confirm that the cable industry has entered a new era of "material defining performance, digital driving efficiency." Enterprises need to find a balance between green compliance and technological innovation, otherwise they will face double elimination.
