Description

technical field [0001] The invention belongs to the field of cable sheath materials, and relates to a cable sheath material for communication equipment and a preparation method thereof. Background technique [0002] The wire and cable industry is the second largest industry in China after the automobile industry, and the product variety satisfaction rate and domestic market share both exceed 90%. Worldwide, China's wire and cable output has surpassed that of the United States, becoming the world's largest producer of wire and cable. Commonly used cable materials can be divided into bare wires, insulated wires, heat-resistant wires, shielded wires, power cables, control cables, communication cables, radio frequency cables, etc. according to their uses. The communication cable is a communication line composed of a cable core made of multiple insulated wires or conductors and an outer sheath that protects the cable core from moisture and mechanical damage. In places where the...
