Description

technical field [0001] The invention belongs to the technical field of polymer material modification, and specifically relates to an environment-friendly, non-toxic, high-insulation and low-temperature-resistant polyvinyl chloride cable material and a preparation process thereof. Background technique [0002] With the rapid development of the national grid construction, more and more high-voltage power cables are used, and people's requirements for power supply reliability are getting higher and higher. In order to ensure the safe and stable operation of cables, all kinds of safety problems such as grounding wires and coaxial cables in newly commissioned and operating lines should be eliminated. [0003] At present, coaxial cables and grounding cables are mostly made of ordinary polyvinyl chloride insulation materials, and the insulation thickness is 2.0~2.5mm. Due to the long-term outdoor operation and the relatively low winter temperature in most parts of northern my coun...
