Description

technical field [0001] The invention relates to the field of cable protection tubes, in particular to a high-strength cable protection tube and a preparation method thereof. Background technique [0002] Cable protection pipe refers to a protective pipe with a certain mechanical strength that is laid on the outer layer of the cable to prevent the cable from being damaged. The cable protection tube is mainly installed at the intersection of communication cables and power lines to prevent short-circuit accidents caused by disconnection of power lines. Cable protection tubes generally need to be used in various harsh environments, including seabed, snow, and saline-alkali environments. Due to the harsh use environment, it is necessary to strengthen and modify the plastic material to make it have higher rigidity to resist external loads; it needs to have strong cold and heat resistance, and it is not easy to be corroded, not easy to deform, and has a long service life. .
