Description

Technical field [0001] The invention relates to the technical field of cable sheaths, in particular to a weather-resistant and wear-resistant cable sheath material. Background technique [0002] Cable jacketing sleeves are mainly installed underground or on the surface to protect cables from corrosion or damage, and prevent short-circuit accidents caused by disconnection of power lines. Cable sheaths generally need to be used in a variety of harsh environments, including the seabed, snow, and salt-alkali environments. The material for preparing the cable sheath should have high heat resistance, insulation performance, compression resistance, impact strength, flame retardancy, low temperature resistance, and the cable sheath should be light in quality and high in strength. Construction and laying methods Simple and long service life. The performance of the current cable sheath can not meet the requirements of society, and its weather resistance and wear resistance need to be fur...
