Description

technical field [0001] The invention relates to a high tensile strength cable sheath tube and a production method. Background technique [0002] Cable protection sleeve is a new type of sleeve material popularized and used in electric power engineering. With the rapid development of power cable buried laying projects, higher requirements are put forward for cable sleeves, which are the most commonly used electrical insulation tubes for protecting wires and cables. It is widely used because of its good insulation performance, high chemical stability, no rust, no aging, and adaptability to harsh environments. [0003] At present, most of the common cable sheathing tubes are mainly made of polymer materials such as polyethylene, polypropylene, polyvinyl chloride, etc., and certain additives are added to improve their related properties. However, these current cable sheathing tubes are still unsatisfactory in terms of strength, rigidity and flame retardancy, or there is only a...
