Description

technical field [0001] The invention belongs to the technical field of insulating materials, and in particular relates to an insulating sheath for electric equipment and a preparation method thereof. Background technique [0002] Cable is a general term for items such as optical cables and cables. There are many uses of cables, mainly used for multiple functions such as control installation, connection equipment, power transmission, etc. It is a common and indispensable thing in daily life. [0003] The cable sheath is a structural part that protects the insulation layer of the wire and cable from environmental factors. The main function of the cable sheath is to improve the mechanical strength of the wire and cable, chemical corrosion resistance, moisture resistance, water immersion, and the ability to prevent the cable from burning. Cable sheaths include rubber, plastic, nylon and other varieties, all of which have their own excellent characteristics. For example, neopre...
