Problems solved by technology

[0002] The continuous development and application of electric energy is a double-edged sword. The convenience brings irreplaceable advantages to people. The other convenience is that people must always be alert to the occurrence of house fires. Electricity has become a common topic of the times, and fireproof cables have emerged as the times require. Although the technology is increasing day by day, fireproof cables still have certain limitations in terms of time, temperature and effect. At the same time, there are also problems such as moisture absorption and poor flexibility of the fireproof layer. Not only Affects the safety of electricity use and increases the difficulty of installation
