AI Technical Summary

Problems solved by technology

However, it also has obvious defects, and its main limitations are as follows: 1. The same body manufacturing, when there is a problem with one line in the cable, it cannot be replaced independently, and it may cause a short circuit of the cable when it encounters external damage such as lightning strikes and corrosion. Generate a large current, damage the equipment and damage the cable; 2. The shielding between the cable core and the fiber core is complicated, and the signals are easy to interfere with each other, which affects the use of the cable; 3. Long-distance power transmission is for high voltage Or ultra-high voltage (36kV ~ 500kV) demand, so that the corresponding equipment is required to generate output power at the user control end (power output end), and at the
