Problems solved by technology

Fire-resistant cables mostly work in high-temperature environments. When a fire occurs, it is necessary to ensure smooth power and communication within a certain period of time, which requires good flame retardancy. The insulation performance of existing fire-resistant cables is poor in high-temperature environments. , which brings great problems to people's use, and also has potential safety hazards
Good cable insulation materials need to have high flame retardancy and meet environmental protection requirements; however, the cross-linked polyolefin cable insulation materials prepared by the prior art contain halogens while having good flame retardancy, which is harmful to the environment. It will cause pollution and cannot meet the requirements of environmental protection

Description

technical field [0001] The invention relates to a cable, in particular to a formula for an environment-friendly cable insulating layer material, and belongs to the technical field of electric cables. Background technique [0002] With the development of society, cables are used more and more widely, and there are more stringent and diverse requirements for the performance of cables. Fire-resistant cables mostly work in high-temperature environments. When a fire occurs, it is necessary to ensure smooth power and communication within a certain period of time, which requires good flame retardancy. The insulation performance of existing fire-resistant cables is poor in high-temperature environments. , bring very big problem to people's use, also have potential safety hazard. Good cable insulation materials need to have high flame retardancy and meet environmental protection requirements; however, the cross-linked polyolefin cable insulation materials prepared by the prior art c...
