AI Technical Summary

Problems solved by technology

Although it can meet the requirements of oil resistance and flame retardancy, it cannot meet the requirements of low-smoke and halogen-free, low temperature resistance, oil resistance, flame retardancy, high temperature resistance, and weather resistance at the same time. It will inevitably release acid gas during use, which will corrode the fan equipment. At the same time, it also affects the surrounding environment and human health; or the oil resistance, flame retardancy, weather resistance, and oil resistance cannot meet the requirements, which seriously affects the performance and service life of the cable.
