Problems solved by technology

[0002] Since mine cables are mostly used in harsh underground environments, most of them are high-temperature, flammable, and highly corrosive. After several years of rapid development, my country's mine cables have formed a considerable scale, and the production capacity has greatly exceeded this year's forecast demand. At the same time, wire and cable companies are facing the problem of urgently improving the technical content of their products. How to prepare a mining cable that can improve permanent compression deformation, high temperature resistance, and excellent anti-aging performance has become a technical problem that needs to be solved at present.
