Problems solved by technology

[0002] Because power cables are often used in some harsh environments, the requirements for waterproof and aging performance of power cables are extremely high during long-term use, and in environments that often need to be pulled, the toughness of power cables is also required to be high. Existing These problems that currently exist in the technology need to be solved urgently
