The Latest Developments And Technological Trends In The Cable Industry

In 2023, the 35 kV kilometer-scale HTS power transmission demonstration project developed by the Shanghai Cable Research Institute achieved full-load operation, with a transmission capacity of 2,000 amperes. Its efficiency is 4-6 times higher than traditional cables, with near-zero energy loss.

 

Technological Innovation: From Superconducting Cables to Smart Grids

 

 

Commercial Breakthrough of High-Temperature Superconducting (HTS) Cables

 

In 2023, the 35 kV kilometer-scale HTS power transmission demonstration project developed by the Shanghai Cable Research Institute achieved full-load operation, with a transmission capacity of 2,000 amperes. Its efficiency is 4-6 times higher than traditional cables, with near-zero energy loss. Using yttrium-barium-copper-oxide superconducting materials operating in -196°C liquid nitrogen, the project solves land scarcity for power transmission in urban cores, paving the way for upgrades in megacity grids.

 

● International Comparison: While Germany's Essen laid a 1-kilometer HTS cable (10 kV, 40 MW) in 2013, Shanghai’s project leads in voltage class, transmission capacity, and commercial readiness.

 

Anti-Twist and Liquid-Cooled Charging Technology Innovations

 

● Anti-Twist Cables: Sichuan Shulian Cable Group's national patent (CN 222705211 U) extends cable service life by 30% through a spring-coil design and flame-retardant wear-resistant coating, ideal for industrial robots and complex mechanical environments.

 

● Liquid-Cooled Charging Cables: Omico's liquid-cooled cables support 600A current and 600kW power, maintaining temperatures below 60°C via internal coolant circulation. Compatible with 800V high-voltage supercharging platforms, they reduce charging time to under 10 minutes.

 

5G Smart Factories and IoT Integration

 

Zhongchen Cable launched a 5G fully connected smart factory, achieving a 40% productivity boost and 99.95% in-process inspection pass rate through 30+ intelligent applications (e.g., AGV logistics, machine vision quality control). The factory enables "cloud-based" equipment management and real-time energy monitoring, driving industry-wide digital transformation.
