Problems solved by technology

The polyvinyl chloride cable material of the prior art will release a large amount of toxic gas and smog when burned, which is easy to pollute the environment
Polyolefin materials meet the requirements of energy saving and environmental protection, but are still insufficient in flame retardancy and wear resistance. Therefore, in the prior art, inorganic flame retardants are generally added to improve their performance, but inorganic materials and polymer materials exist Compatibility problems can easily lead to a decline in the mechanical properties of materials, so it is difficult to obtain products with good comprehensive properties

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a wear-resistant and weather-resistant insulating material used for preparing cables for power distribution cabinets in substations. Background technique [0002] In recent years, with the rapid development of electricity, more and more substations have been built, and the demand for power distribution cabinets has also increased. The demand for cables as the core components of power distribution cabinets is also increasing day by day, so there is a special need for cable materials with excellent comprehensive performance, energy saving and environmental protection. The polyvinyl chloride cable material in the prior art will release a large amount of toxic gas and smog when burned, which is easy to pollute the environment. Polyolefin materials meet the requirements of energy saving and environmental protection, but are still insufficient in flame retardancy and wear resistance. T...
