Problems solved by technology

However, due to the harsh application environment of cable protection tubes, ordinary plastic tubes have poor compressive resistance and are prone to rupture and damage due to large extrusion and collisions, and ordinary plastic tubes are easy to corrode or age in various environments with different pH values. Therefore, when ordinary plastic tubes are used as cable protection tubes, the service life of the cable protection tubes is low, and the plastic tubes are easily damaged, causing leakage or short circuit accidents of internal wire leakage or wire disconnection.

Description

technical field [0001] The invention relates to the technical field of cable protection tube materials, in particular to an impact-resistant and anti-aging cable protection tube material and a preparation method thereof. Background technique [0002] Cable protection tube is also known as power cable protection tube, cement cable protection tube, power row tube, power cable protection tube, etc. 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, which may cause communication cables and wire ropes to be charged. The cable protection tube is used to protect cables, switches, and core boards, so that the whole machine will not be burned out, and it also plays a certain role in isolating the interference of the power line magnetic field. [0003] Due to the development of the times, composite protection tubes made of cement or other metal or non-meta...
